NPK Organic Compound Fertilizer Application Methods

NPK compound fertilizer has comprehensive nutrition, high content and good physical properties. But how to use NPK compound fertilizer correctly? Three problems should be paid attention to in the application process.

First of all, NPK compound fertilizer should be selected according to different soil and crops. Only in this way can its fertilizer efficiency be exerted. Rice, wheat, corn and other food crops need more nitrogen fertilizer, nitrogen and phosphorus compound fertilizer can be used; Leguminous crops can fix free nitrogen in the air, and can apply phosphorus and potassium fertilizer. Some economic crops can choose ternary or multivariate compound fertilizer suitable for local soil and climate conditions.

Generally speaking, compound fertilizer should be used as base fertilizer, and simple fertilizer can be used as top fertilizer at peak and critical period. At the same time, organic fertilizer must be applied.

Third, the method should be appropriate. In various compound fertilizers, the proportion and form of various nutrients are different. In addition, soil and crop types are different, so fertilization methods should not be the same, should be treated differently.

Clay soil fertility should be applied deeply, sandy soil fertility can be removed easily, and a small amount of fertilizer can be applied. The compound fertilizer containing ammonium nitrogen should be covered deeply to reduce the loss. How to make npk fertilizer granules at large scale? Go here for more.

The compound fertilizer containing phosphorus and potassium should be applied in a centralized way and near the root system to avoid nutrient fixation and promote the absorption and utilization of crops. Generally speaking, expensive potassium dihydrogen phosphate should not be used as base fertilizer, but as external fertilizer or seed soaking.

Quality Organic Fertilizer Production Solutions

The fertilizer machine manufacturer of the organic fertilizer production line will tell you the reason for the caking of organic fertilizer. The sx manufacturer of the organic fertilizer production line said in the last article that in fact, the premise of prevention is to find out the cause of caking. Everyont also knows that caking is not conducive to the use of organic fertilizer, and has a certain impact on the production and use of organic fertilizer. Want to answer why pig manure organic fertilizer production line caking.

Small Scale Fertilizer Production Line
Small Scale Fertilizer Production Line

We usually use the materials for fertilizer production, such as ammonium salt, phosphate, trace element salt, potassium salt, etc., most of which contain crystal water and are easy to absorb water and caking, such as ammonium sulfate, which is easy to caking in use. When urea meets with trace element salt, it is easy to agglomerate when releasing water, mainly because urea replaces trace element salt. The crystal water becomes mushy and agglomerates.

Compost Made from Organic Waste
Compost Made from Organic Waste

In the process of chemical fertilizer production, chemical fertilizer production is generally non closed. In the production process, the higher the air humidity is, the easier the fertilizer is to absorb water and caking. If the weather is dry or the raw materials are dry, the fertilizer will not agglomerate easily.
Organic fertilizer production line

The higher the room temperature of extruder granulator, the easier to dissolve. Generally speaking, raw materials will dissolve in their own crystal water, leading to caking. The higher the temperature of nitrogen, the water will evaporate and not caking easily. The temperature is usually higher than 50 ℃. We usually need heating to reach this temperature.

Cattle and Cattle Waste
Cattle and Cattle Waste

The greater the pressure applied on the fertilizer, the easier the contact between the crystals and the easier the agglomeration; the smaller the pressure applied, the less the agglomeration.

The longer the fertilizer is placed, the easier it is to agglomerate. The shorter the time, the less likely it is to agglomerate.

Only when the production line of organic fertilizer does not ignore the problem of caking, can we find out the reason of caking. Serious caking may even affect the use efficiency of organic fertilizer.

How organic fertilizer is made?

The organic fertilizer production line from sx organic machines is designed for the production of organic fertilizer granulator. In the process of organic fertilizer production, different types of fertilizer equipment are equipped to complete the production process.

2. The general production process of organic fertilizer requires the content of nitrogen, phosphorus and organic fertilizer granulator or disc granulator or roller granulator; the production process of organic fertilizer requires the content of nitrogen, phosphorus and potassium to be more than 4% and the content of organic matter to be more than 30%. So organic fertilizer can be mixed, crushed and packaged.

In addition, fertilizer equipment such as drum granulator, organic fertilizer granulator, disc granulator or roller granulator is required for organic fertilizer granules. The production of organic fertilizer requires the same raw materials as powder fertilizer, but after adding binder (bentonite or green palygorskite), the final particles need to be dried by rotary dryer.

Organic fertilizer production line

There is also an organic fertilizer with livestock manure, domestic waste and plant straw as the main raw materials.

The production process of the organic fertilizer is as follows: raw material drying, crushing, fermentation, mixing (mixed with chemical fertilizer). And other organic or inorganic substances, so that nitrogen, phosphorus, potassium content into particles (or not into particles, powder) and then packaging.

Bio Fertilizer Production Line

Fertilizer Granulation Technology

Since the mid-1980s, extrusion method has been greatly developed, and more and more industrial production equipment has been established in various places. Now, extrusion granulation compound fertilizer production line technology has become an international fertilizer research center. A new production technology of compound fertilizer was recommended.

Bio Fertilizer Granulation Line
Bio Fertilizer Granulation Line

Working principle of extrusion granulation of compound fertilizer production line:

The material is fed into a pair of counter rotating roll gaps (bite zones) of the roll granulator. To form a compact sheet of material under extrusion. After crushing and sieving the flake, the granular product with the required size can be obtained.

The formation mechanism of extruded pellets in compound fertilizer production line is as follows

At present, the general explanation of the material forming mechanism in the extrusion process is that after the material is compressed, the particles will be rearranged, and the air between the particles will be removed, so as to remove the voids in the material.

After further compression of the material, due to their different characteristics, the material particles will be in the following two situations: when the material is fragile, some particles will break, thus filling the remaining gap. In addition, if the atoms or molecules in the environment can not be rapidly decomposed into new particles, the free chemical bonds on the broken new surfaces will form strong recombination bonds when the new surfaces contact each other.

In the extrusion process of pelletizer used for fertilizer, the particles of material can also form solid bridge. The energy supplied to the system in the form of pressure will generate heat energy at the contact point of the material particles, thus melting the material. When the temperature of the material decreases, a solid bridge is formed.

Main equipment of extrusion granulation compound fertilizer production line

1. Forced feeder
One of the advances in extrusion granulation compound fertilizer production line technology is the use of forced feeding in fertilizer granulator, which is usually achieved by the driving force of screw. The extrusion process adopts the form of gravity free feeding.
Forced feed, easy to control the feed speed and reduce the slip phenomenon in the bite area. More importantly, the material can be partially degassed and compacted in advance in the forced feeder, thus greatly improving the product quality.
2. Crushing equipment
The flakes obtained by extrusion must undergo a so-called granulation process, such as crushing and sieving, to obtain the desired size of particles. The progress of pelletizing equipment is mainly due to a lot of experience gained in the relationship between the form of crushing equipment and products.

Zhengzhou SX Granulator Manufacturing Factory vigorously promotes energy-saving, environmental protection, high-efficiency new extrusion granulation compound fertilizer production line technology, and continuous progress and improvement.

20t per hour drum granulation plant layout

In the pelletizing process of drum fertilizer granulator, the powder material is mainly cladding type, so the material circulation volume needs to be large, so that the material can form large particles in the cladding process. When the water content in the material is large, the water injection should be reduced to make the fertilizer made into granules absorb less water.

When granulating with this combination method, if the water content in the material is small, more water injection is needed. Because the materials are combined with each other, the gap between the powder particles needs to be filled with water. As the understanding of granulation process has been deepened, some suitable monitoring tools have been developed, so the granulation process can be simulated and controlled automatically by computer.

How to make granules fertilizer with pan granulation machine?

Organic-inorganic compound fertilizer is a compound fertilizer that integrates organic matter and inorganic fertilizer. Organic-inorganic compound fertilizer has various components, which can not only provide crop nutrients, but also improve soil biological activity and soil fertility, so it is widely used in cash crops.

Organic matter is an important component in organic-inorganic compound fertilizer, and its content directly determines the actual effect of bio-organic compound fertilizer. Therefore, the granulation process of organic-inorganic compound fertilizer production line is particularly important. The organic fertilizer disc granulation production line can realize the complete treatment of organic-inorganic compound fertilizer.

For the pan granulator, the addition of organic matter is also the key to granulation. Want to know how does the granulator make fertilizer granules by wet granulation method, welcome to https://www.fertilizermachinesale.com/pan-granulation-process/

Disc Pelletizer for Small Scale Cow Farm Manure Granualtion
According to the actual situation, several kinds of materials with abundant raw materials, low price and convenient processing can be selected as the raw materials of the pan granulator.

Organic fertilizer: chicken manure, pig manure, peat, plant ash, etc.
Inorganic fertilizers: urea, ammonium sulfate, superphosphate, calcium magnesium phosphate, potassium sulfate, potassium chloride, etc.

Organic compound fertilizer disc granulator

Organic fertilizer has strong water absorption and looseness, and its water content, fineness and other factors have a greater impact on granulation. Therefore, organic matter plays an important role in the production of disc granulators. On the premise of keeping the compound fertilizer and other inorganic nutrients unchanged, increasing the input of organic matter is an important way to improve the quality of biological compound fertilizer.

However, organic matter has strong dispersibility and has a greater impact on granulation. The organic content is too high, which is not conducive to the production of the pan granulator.

Experiments show that in the production line of organic fertilizer disc granulation, the amount of organic matter is about 25%-35%, and a better granulation effect can be obtained. The process of organic fertilizer disc granulation production line is suitable for the production of granular organic-inorganic compound fertilizer.

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.

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.

Technological implementation elements:

The granular organic fertilizer provided by the invention is fermented by pig manure, chicken manure, cow manure, bagasse, wheat straw and corncob, and is made into granular form by adding pond mud and beeswax, which has strong fertility and durable fertility, and can effectively improve soil, alleviate soil hardening and improve soil structure; after being used as base fertilizer before sowing, it can be applied to Zhuang village. Crops play an important role in strengthening seedlings and increasing yields.

By adding microbial agents, controlling the species, quantity, fermentation temperature and time of microbial strains, the fermentation substrates such as pig manure, cow manure and chicken manure can be fully fermented, and the macromolecular organic substances can be converted into small molecular substances that can be absorbed by plants with strong fertility. Fermentation products were mixed with pond mud, wheat straw powder and beeswax to form granular fertilizer, which was convenient for preservation and application. Pond mud is rich in nutrients and microorganisms, and it is a high-quality fertilizer. Beeswax plays a binding role. The prepared feed particles are compact and not easy to loosen. Beeswax is a natural substance secreted by bees, which can be decomposed in nature. Compared with chemical binders, beeswax is more green and environmentally friendly.

The raw materials of the invention are all from natural waste resources, so there are no side effects on crops, effectively solving the problem of farming and fertilization, reducing farmer’s planting cost and improving farmer’s income.
