Time to use organic fertilizer

Most garden soils contain the most basic necessities. But it may not be enough. More is needed to fully develop.

When nutrition is needed for crop growth
Brass, potatoes and some other plants are more demanding – compost or dry manure is essential – poultry manure particles and buttons continuous planting season

Organic fertilizers are very useful because supplements see particles of poultry manure again
Lawns, shrubs, hedges, trees… Garden compost and manure is still a great supplier – find more lawn and shrub fertilizer here.

When growing on thin fertile soil

Work in manure – continue to use organic fertilizer to make compost of better quality, and plant cloves and beans as green fertilizer digs. Check out the organic base fertilizer and decarbonized rock dust link here.
Some products cannot use organic fertilizer. You must consider the following:

Where does organic fertilizer come from? For example, are algae threatened by commercial development? Will mining calcified seaweed destroy marine life? Does your fish fat come from fish waste?

Do manufacturers use important resources or are they involved in pollution? For example, burning carbon from natural gas used to produce chemical nitrogen,
How can you do this? Transporting large amounts of fresh manure?
Is it excessive or wasteful? The use of urea has attracted many supporters, but they are all considered bad for organic gardening, are soil structural microorganisms destroyed?

Fertilizer Coating Process

Coated fertilizer is a kind of NPK compound fertilizer widely used in agricultural production. It is popular with farmers for its low cost and high fertilizer efficiency. When NPK chemical fertilizer production line produces compound fertilizer, the treatment of coating machine is increased, which greatly improves the influence of fertilizer on crops.

The controlled release time of coating controlled release fertilizer is long, and the fertilization effect can be as long as 2 months to 1 year. NPK coated fertilizer can promote root growth, make crops mature early, solve the problem of crop fertilizer shortage caused by severe drought, and create favorable conditions for high yield of various crops.

NPK coated fertilizers can be used in the production of many crops. The output of rice, wheat, peanuts, corn, cotton, tobacco, vegetables, fruit trees, flowers, lawns and other crops increased significantly.

How to process NPK fertilizer production line

In the process of coating fertilizer, NPK fertilizer production line uses various nutrients, such as blood acid as coating layer, and the fertilizer is coated by coating machine. The coating can greatly reduce the loss of fertilizer and soil fixation, and greatly improve the utilization rate of fertilizer. The proportion of NPK and its trace elements in coated fertilizer processed by NPK fertilizer production line is determined according to crop demand and different soil conditions.

When we use NPK fertilizer production line to process coated fertilizer, we can produce special or general coated compound fertilizer for crops. This special NPK compound fertilizer has high fertilizer efficiency.

The application amount should be reduced according to the specific situation of crops and soil. The time interval of fertilization should be determined according to the length of controlled release cycle.

Therefore, when farmers use coated compound fertilizer, the production cost will be reduced.

Fermentation Technology in Organic Fertilizer Production

What are the phases of maturation and development in natural manure creation line?

1. In the beginning phase of stacking: when the temperature of the reactor ascends to around 50 ℃, it is called warming stage. The reactor temperature scope of 25 ~ 40 ℃ is reasonable for some moderate temperature microbial exercises.

2. High temperature stage: following 2 ~ 3 days, the reactor temperature ascends to 50 ~ 60 ℃, which is called high temperature stage. As of now, countless thermophilic microorganisms supplanted the first mesophilic microorganisms, and humification measure was done simultaneously.

How to pass judgment on the fruition of aging in natural manure creation line?

3. Cooling stage: the reactor temperature continuously dips under 50 ℃, which is called cooling stage. As of now, the species and amount of microorganisms in the reactor are more than those in the high temperature stage. In this stage, the decomposable natural material grid in the reactor diminishes pointedly, and humification is predominant.

4. The gathering of humus in the fertilizer expanded essentially. The stacking materials ought to be compacted and covered with soil, so the anaerobic cellulose disintegrating microscopic organisms can likewise overwhelmingly decay cellulose, and gradually complete the later development.

Through the over four phases, the fertilizer was totally matured and deteriorated. Go to https://compostturnermachine.com/compost-tank/ for more details.

Dry Granulation Fertilizer Production Technology

Non drying fertilizer granulation technology is mainly used for products with low water content. Generally, moisture content below 10% is a critical value. (some materials can reach 16%, for example, some contain only crystal water). Some organic fertilizer manufacturing processes have low water content, no need to dry, and save energy.

Dry granulation

The double roller granulator belongs to drying granulation equipment without drying process. It has high granulation density, good fertilizer efficiency and high organic content. The particles are flat and round, suitable for compound fertilizer.

Most of the particles produced by dry granulation are irregular particles (such as ordinary particle size potassium fertilizer), and their shape is similar to the shape of small gravel. The double roller granulator can produce all kinds of high, medium and low concentration NPK compound fertilizer and organic-inorganic compound fertilizer granulation, which meets the requirements of energy conservation and environmental protection.

Fertilizer granulation technology without drying extruder

The dry powder extruder consists of five parts: frame, head, pressure reducer, motor and crusher. It has the advantages of simple structure, high stability, convenient operation and maintenance, and strong adaptability of raw materials.

Organic fertilizer fermentation

In the process of organic fertilizer manufacturing, fermentation products are often not handed in, which is usually caused by the viscosity of the object in the fermentation reactor. The trough turning machine used in organic fertilizer fermentation usually processes organic wastes such as sludge waste, slag cake, straw sawdust, livestock manure and sugar mill sludge.

Due to the different consistency of materials and different moisture content of materials, it is easy to see the difficulty of turntable treatment.

How to solve the problem of turning over materials of composting truck

The start-up temperature of the stacker should be better than 15 ° C (it can be operated all year round, not affected by seasons, ferment indoors or in Greenhouse in winter), and the fermentation temperature should be controlled below 70-75 ° C.

Turning machine for tank composting

1 kg starter can ferment about 10 tons of sludge and cow dung. According to the weight ratio, add about 30-50% cow dung, or straw powder, mushroom residue, peanut shell powder, or rice husk, sawdust and other organic materials to regulate ventilation.

If rice husk and sawdust were added, the fermentation time should be prolonged due to the high content of cellulose lignin.

Strain dilution: mixing and diluting 5-10 kg rice bran (or wheat bran, corn flour and other substitutes) per kilogram of appetizer, and then evenly sprinkle them into the material pile, the use effect will be better.

The moisture content of fermentation materials should be controlled between 60-65%. Moisture judgment: hold a piece of material tightly, the watermark of finger joint does not drop, and the ground is scattered properly. Fermentation with less water is slow, but fermentation with more

Construct fermentation reactor while spraying bacteria. The height and volume of the reactor should not be too short or too small. The fermentation reactor should be 1-1.3 meters high and 2-3 meters wide, with unlimited length.

The above is a brief description of the use of compost transfer machine in the fermentation process of organic fertilizer manufacturing process. We are a chemical fertilizer manufacturer, providing all kinds of composting turntable equipment.

How to make fertilizer granules by extrusion method?

Roller granulator specially designed for fertilizer manufacturing process. Fertilizer granulator is the main compound fertilizer granulation equipment, which has a broad market in domestic and international markets.

Processing principle of fertilizer roller extruder granulator

Roller extrusion granulator is a kind of drying granulation process which uses pressure to gather solid materials. The material is extruded by two counter rotating rollers, which are driven by an eccentric sleeve or hydraulic system. When extruding the solid material, the air between the powder particles is removed first, and the particles are rearranged to eliminate the gap between the materials.

When the brittle material is extruded, some particles are crushed and the fine powder fills the gap between the particles. In this case, if the newly formed free chemical bonds on the surface cannot be quickly saturated by the atoms or molecules in the surrounding atmosphere, the newly formed surfaces will contact each other and form strong recombination bonds.

When the material is extruded, the particles will deform or flow, resulting in a strong van der Waals attraction. In the extrusion process, the energy formed by pressure forms a hot spot at the contact point between the particles, which leads to the melting of the material, the temperature drop and the material cooling to form a fixed bridge. The thickness of large parts produced by extrusion is 5-20 mm, and the surface density is 1.5-3 times of feed. Large pieces, crushed and screened to obtain the required particles.

Fertilizer roller extruder granulator

The double roller of granulator is the key of fertilizer manufacturing process. The following is a brief description of how to adjust a volume.

1. Adjustment of roller clearance

First, loosen the bolts on the bearing housing, rotate the eccentric sleeve, and adjust it to the required thickness, so that the eccentric sleeve exerts radial force on the drive shaft. When adjusting the gap between the two rollers, the two rollers cannot collide. The minimum value should be maintained between 0.4 and 0.6 mm. Then tighten the bolts on the bearing pedestal.

2. Adjust the ball sleeve accordingly

First, loosen the bolts on the bearing seat, such as the axial dislocation of the ball sleeve, adjust the two eccentric sleeve cover bolts to make the shaft move left and right, so as to adjust the ball sleeve relatively. Tighten the bolts on the bearing housing. If the ball sleeve is not up to right, first release the bolt of the adjusting board, then adjust the top line of the concave part of the adjusting board, so that the reverse shaft can slightly turn to the spherical socket. Then tighten the bolts of the commissioning panel and loosen the top wire for use.

How to make organic fertilizer?

With the popularization of organic fertilizer, the use of organic fertilizer production equipment is also greatly increased, which makes the demand of organic fertilizer equipment increase year by year.

Therefore, the standard operation of organic fertilizer equipment has become the focus of attention. The following is a brief introduction to the matters needing attention when the organic fertilizer manufacturing process is newly built and the project is put into use.

1. Before the start-up of organic fertilizer production equipment
Since all parts of the new equipment are not yet in operation, it is necessary to heat up the equipment for the first time, which usually takes 40-50 minutes. For a specific operation, first raise the temperature, pull the motor V-belt by hand until it is released, and then continuously pull the motor 8-10 times according to the normal operation option. Then keep heating for about 10 minutes.

2. Temperature control after start-up

Before starting the machine, we have made a preliminary temperature adjustment on the equipment. The material treatment of organic fertilizer equipment in the production process is determined by the characteristics of the material itself. Therefore, heating should be continued after start-up, because normal production requires continuous heat supplement; different temperatures are adjusted according to different properties of plastics.
Manufacturing technology of organic fertilizer

3. When the fertilizer manufacturing process works normally

During normal operation, the temperature of the drum granulator should be stable and should not be high or low. The temperature should be about 200 ° C near the nozzle until the machine head. At this temperature, most materials can be treated well. For the double roller granulator, granulation can be carried out at normal temperature, and the moisture content of materials should be paid attention to during the granulation process.

4. Close the organic fertilizer manufacturing process

First of all, cut off the power supply of the host, and the plug of the machine head (the part with wrench) must be removed. Preheat separately before next use. As the organic fertilizer production equipment is heavy machinery, the corresponding operation procedures and production projects must be strictly observed when operating the organic fertilizer granulation equipment to ensure the safety of production. When installing, pay attention to whether the host is vertical to the ground. After installation, first check whether the screw of the machine is loose and whether the air box of the main unit door is fixed. If there is any looseness, please strengthen it to avoid accidents.

Plants for Biofertilizer Production

There are many kinds of organic fertilizer, and bio organic fertilizer is the leader. Biological fertilizer is a kind of fertilizer which combines microbial fertilizer and organic fertilizer.

Bio organic fertilizer products not only contain high organic matter, but also contain microorganisms with specific functions. The microorganisms contained in bio organic fertilizer products should have certain fertilizer functions, such as improving soil fertility, producing and assisting crops to absorb nutrients, activating insoluble compounds in soil for absorption and utilization of crops, or producing various active substances, disease resistant and disease resistant substances.

Biological planting can stimulate and regulate crop growth, reduce or reduce the occurrence of plant diseases and insect pests, and improve the quality of agricultural products.


Biological fertilizer plant mainly includes fertilizer granulator, crusher, mixer, drum machine, etc. Compared with common organic fertilizer, biological fertilizer production technology content is higher.

In addition to adding microbial agents to promote the maturity and decomposition of organic materials in the decomposition process, so as to achieve the purpose of directional decomposition and deodorization, microorganisms with specific functions need to be added in the production of microorganisms to improve the effect of products.

Fertilizer manufacturers will remind you that biological fertilizer is different from ordinary organic fertilizer in the production process. In the biological fertilizer plant, there is no difference from the ordinary organic fertilizer production equipment. The only difference is how to protect functional bacteria, improve the survival rate of bacteria in the production process, so as to maximize the efficiency of fertilizer.

Biological fertilizer plant

The following five points should be paid attention to when processing biological fertilizer production plant

(1) When processing and producing fertilizer, the drying temperature should not exceed 80 ° C, otherwise the number of active bacteria in biological fertilizer will be affected.
(2) When storing and transporting biological fattening, it is necessary to avoid damp or rain;
(3) In the process of biological fattening, direct sunlight should be avoided.
(4) The physical, chemical and biological factors of soil must be taken into account when using biological fertilizer.
(5) Biological fertilizer cannot be used together with pesticide and physiological acid fertilizer.

Humic Acid Fertilizer Production

Function and production equipment of low acid fertilizer
Blood acid fertilizer plays an important role in maintaining soil activity. In industry, manure, straw, mushroom residue, sawdust and other wastes are fermented by organic fertilizer production equipment, and then processed into organic fertilizer. This organic fertilizer product is rich in acid and blood.

1. Blood acid can improve nitrogen use efficiency

Nitrogen fertilizer is an indispensable fertilizer for plant growth, mainly urea and carbamine. When urea and ammonium bicarbonate are used in this field, they will soon disappear with the flow of air and water. Only 30% of nitrogen can be absorbed and utilized by crops. Aromatic nuclei, hydroxyl groups, carbon groups and other acidic functional groups in methanoic acid can react with nitrogen to form stable new ion groups. These compounds exist in the soil for a long time, and gradually decompose and release nitrogen, so that plants can slowly absorb.

2. It has synergistic effect on phosphate fertilizer

When the available phosphorus fertilizer is applied into the soil, the phosphorus element will be fixed by the metal ions in the soil, so that the available phosphorus can be converted into delayed phosphorus or ineffective phosphorus. The aromatic core, hydroxyl group, carbon group and other acidic functional groups in methanoic acid can react with phosphorus, making phosphorus become soluble phosphorus, increasing the activity of phosphorus element, which is easy to be absorbed by plants. According to statistics, the fertilizer efficiency of phosphate fertilizer can be increased by 5-10% after adding Heye acid fertilizer. Get more professional info on organic fertilizer production, welcome to https://organicfertilizerproductionline.com/

3. It has synergistic effect on potassium fertilizer

It can not only prevent the loss of potassium ion in sandy soil, but also prevent the immobilization of potassium in cohesive soil, and increase the utilization rate of potassium fertilizer by about 5%. In order to improve fertilizer efficiency, NPK fertilizer and blood acid organic matter are processed by fertilizer granulator in the process of organic fertilizer production.

4. It has the function of retaining water and fertilizing

Blood acids interact with calcium ions in soil to form flocculation and precipitation gel, combine soil particle cement, transform soil particles into small reservoirs and reservoirs, retain water and fertilizer, increase soil voids, and improve soil water and fertilizer retention capacity.

New Developed Machines for Organic Fertilizer Production

1. The necessity of developing new organic fertilizer. Chemical fertilizer is one of the decisive factors for high yield and high quality of grain. The use of chemical fertilizers has made a great contribution to increasing crop yields and alleviating food shortages. Fertilizer plays a very important role.

In the past, the fertilizer used by people was relatively simple, and the fertilizer with efficient utilization of nutrients was lack, and the proportion of various elements could not meet the needs of crop nutrients.

However, commercial granular fertilizer manufactured by fertilizer granulator can improve the utilization rate, ensure food security and reduce environmental pollution. A kind of high-quality compound fertilizer can meet the needs of crops, reduce labor intensity, reduce costs and ensure grain yield.

2. Development direction of new fertilizer. The development trend of new fertilizer is directly proportional to the development trend of agriculture.

Only by speeding up the development of new organic fertilizer, can agricultural production develop in the direction of high yield, high quality, low consumption and high efficiency.

Organic fertilizer production equipment

3. With the development of agriculture, higher requirements are put forward for the production equipment of new organic fertilizer and the nutrient content of fertilizer.

1. High efficiency.

Chemical fertilizer can directly meet the needs of the whole growing period of crops, save time, labor and improve work efficiency.

2. Composite.

The development of new agricultural fertilizer has many functions to meet the growth needs of crops.

3. Lasting.

With the development of agriculture, the requirement of organic fertilizer production equipment is higher and higher. Chemical fertilizer should also meet the different needs of crops. Stable fertilizer conforms to the characteristics of agricultural production and is the main direction of fertilizer development in the future.

Although the production process of organic fertilizer equipment is complex, its production cost and risk are relatively small, and the selection range of raw materials is very wide. I plant to provide professional organic fertilizer production equipment, NPK fertilizer production line, according to the actual situation for the user planning fertilizer technology and site design.

Organic Fertilizer Production Methods

Organic fertilizers have already been used for quite some time. In olden days, before the development of artificial fertilizers, farmers would use available resources off their environment to produce organic fertilizers for produce. Not simply would it be easy to make organic fertilizers, yet it is also economical and effective. Some of the products farmers use to produce organic fertilizers include leftover food, grass, peels of bananas, eggshells, among others. Besides, it can help to save the surroundings since the waste which will go for the garbage bin is commonly used for any more meaningful purpose. Food waste, which is popular to create these fertilizers, is made up of organic matter which is perfect for making fertilizers. You could be capable to convert the wastes in a natural product abundant in nutrients, which will help to boost plant growth. Below are one of the ways you can help make your organic fertilizer.

Sort Your Home Waste.

Since humans will always consume food, it gets very readily available food remnants which you could utilize to help make the fertilizer. Fruit peelings and vegetables are usually extremely helpful, and you must prioritize upon them. Start with keeping eggshells, vegetable remains, and overripe fruits aside. These are generally biodegradable and also a large amount of nutrients. Avoid oils, milk products, and grease because this might cause the pile to get wet and in many cases produce an unpleasant smell. When you sort out these kinds of products, place the items outside, inside a trench and pour some wood ash on the waste. Wood ash is likely to fasten the decomposing process. After adding the wood ash, you might also add other components like sawdust. Animal waste including chicken waste and fresh cow dung is perfect for this process. Use it for those who have livestock. In case you don’t, you could purchase from farmers that have these resources available, for less money.

Cattle and Cattle Waste
Cattle and Cattle Waste

Add Natural Waste And Produce Compost.

After putting every one of these components in just one heap, add natural waste on the mixture. Some examples are grass clippings, vegetable leaves, branches or weeds. If the weeds in your garden have not flowered yet, you could dry them and after that chop those to work as the mulch. Weeds are generally loaded with nitrogen and can help you to protect your plants from losing nutrients. After this, the farmer needs to cover this layer, to guard it from animals or external tampering. The mix should then be left without having interruption for 3 weeks after which the farmer should open the compost heap. You should then rotate the compost using a handle to permit the ingredients to mix well plus, incorporate oxygen in the mixture. It is best to spin the compost a minimum of 3 times every week for excellent results.

Organic fertilizers certainly are a useful component for farmers that have a great deal of organic waste at their disposable. You only have to understand how to utilize the garbage, and you also are ready to go. The process of making organic fertilizer is just not complicated. Consider trying it for those who have not done it before.

Organic Fertilizer from Manure Disposal

With regards to increasing your overall manure management, there has been a series of new and improved technologies which are now being employed throughout the industry. In simple terms, these specialised tech solutions are now serving in order to even successfully reduce the pollution that is certainly created in water ways due to misused manure. However, to be able to properly implement these techniques, a series of management issues needs to be firstly applied. Our article enters into some important points for managing and selling manure.

Cow

Only if manure is effectively managed then the benefits of its use can be captured. This simply just implies that it is going to finally be easier to include it with farming systems while making sure the water pollution remains reduced or rather controlled. When biological decomposition occurs, some by-items are produced and as a result of techniques that manure is treated or perhaps stored, the by-products may also be controlled. This allows the farmer to produce a highly marketable product, in addition to manage the nutrients in the manure along with any odors.

Cattle and Cattle Waste
Cattle and Cattle Waste

Since microorganisms make the potentially profitable waste elements, it really is necessary to provide you with the perfect environment to allow them to thrive. So, if you carefully handle, treat or store your manure inside a desired environment, this encourages the microorganisms to make by-products which are good for you. Additionally, farmers may use biological manipulation to generate the perfect by-product based on their market.

If manure is mixed with a material that may be abundant in carbon as well as enough air, the manure may be easily converted into compost within a case where all the air has become eliminated and heat is added, you’ll have the ability to create biogas, in addition to a stable effluent. However, biologically manipulating your manure is a reasonably challenge with regards to the environment and frequently the type of animal plus the feed that they are fed along with a management system all play a huge role within the microbial activities that occur. Additionally, these activities are greatly affected by the solids content.

People that have a higher solids content are fantastic for undergoing aerobic activity. And if you’re employed to adding bedding along with water and even waste feed, this will likely also affect the microbial activity. Based on the pH values associated, this may also affect those who be involved in creating methane. And as we’ve said before, the meals intake also plays a crucial role in management since higher protein diets build a pretty intense odor.

When it comes to selling, probably the most recommended techniques for selling is usually to simply fill sizable bags and then sell to farmers. You’ll simply must collect the poop when it is fresh and add them to a trusty container for your manure to form. And so they even produce a pretty decent profit dependant upon the animal the manure has come from. However, in order to use the markets by storm, you’ll also have to put a little effort into how you will advertise your product don’t forget to get creative.

Since we conclude we have now just discussed many ways for managing your manure. And that we have likewise given some guidelines on how to produce a profit yourself. Remember, you ought to never apply fresh manure to fruits or vegetables that are eaten raw given that you can generate an E. coli outbreak!

How to make pellet organic fertilizer products?

The invention relates to the field of fertilizer preparation, in particular to a granular organic fertilizer and a preparation method thereof.

Background technology:

In recent years, the input of chemical fertilizer has increased greatly. Due to the single nutrient type, long-term application of chemical fertilizer can easily lead to unbalanced nutrients in soil and food, resulting in nutrient loss, pollution of the environment, and improper application will reduce the quality of agricultural products. Long-term large-scale application of chemical fertilizers will inhibit the activities of soil microorganisms, resulting in a decline in the ability of soil self-regulation. Therefore, although chemical fertilizers contain high single nutrients and use less, long-term application of chemical fertilizers is not advisable under the increasing attention to the needs of the living environment. Therefore, the development of organic fertilizers is of great importance. Significance.

Farm wastes – Ideal materials

Farmyard manure is the accumulation of pig manure, pig, cattle, sheep and other excrement and human excrement, and the organic fertilizer is accumulated. The source of farm manure is wider and its cost is lower. The nutrient content of farm manure is more comprehensive, its fertilizer efficiency is stable and lasting. In addition to nitrogen, phosphorus and potassium, farm manure also contains calcium, magnesium, sulfur, iron and various trace elements, as well as some substances that can stimulate root growth and all kinds of beneficial soil microorganisms. Agricultural fertilizer can improve soil structure, which is rich in humic acid. It can promote the formation of soil aggregate structure, make the soil soft, improve the water and air conditions in the soil, which is conducive to the growth of root system. It can increase soil fertility and water retention performance, improve soil temperature, and promote beneficial microorganisms in the soil. The activity and reproduction of animals; the fertilizer efficiency of farm manure is long.

Hiddien weaknesses

However, most of the nutrients in unfermented and decomposed farm manure are organic or slow-acting, which can not be directly absorbed and utilized by crops. Only when they are decomposed into quick-acting state can they be absorbed and utilized by crops. Therefore, direct application of unfermented farm manure will slow down the efficiency of farm manure. Moreover, the organic fertilizer obtained by direct fermentation has higher moisture content and is not easy to preserve.
