How to make powder fertilizer from cow dung?

Advantages of using Cow Dung Powder Fertilizer Production for Agricultural Application

It is really an age-old tradition to utilize cow dung within the garden. Most farmers use fresh cow manure within their fertilizers to enhance crop production. But, fresh cow dung contains high amounts of ammonia. This usually contributes to plants dying when the farmer applies the manure directly. This is why modern farmers use cow dung powder rather than the raw product. They offer lots of benefits that other manure may not offer.

Bio Fertilizer Mixer

Elements of cow dung powder

Cow dung powder is a mix of numerous things. While the dung includes digested grains and grass, the powder used for fertilizer production experiences a composting process. Cow dung contains approximately 1% potassium, 2% phosphorus, and threePercent nitrogen. Aside from these three essential elements, furthermore, it has a high portion of ammonia that is certainly harmful for pathogens. That is why farmers use composted cow dung to ensure that it doesn’t include the harmful ammonia gas.

Functions of cow dung powder for agricultural applications

Composted cow dung powder adds a lot of organic matter inside the soil that promotes crop growth. It improves the moisture-holding capacity from the soil. So, farmers should water their crops less often. Countries that have scarce water supply use cow dung powder fertilizers to make sure they don’t need to rely heavily on water. The roots of the crop use additional nutrients and water whenever required.

As well as increasing moisture-holding capacity, cow dung powder fertilizer also improves soil aeration. It breaks down the compacted soils and increases porosity, allowing the crops to grow quickly. The healthy bacteria within this sort of fertilizer converts nutrients to several accessible forms that release the main minerals slowly and steadily without burning the tender crop roots.

Composting cow dung powder

Cow dung powder is not only employed in the fertilizers and also spread like a top dressing on crop soil. This nutrient-rich fertilizer is suitable with regards to producing fresh crops at the outset of the growing season.

The composting process starts by collecting cow dung and mixing it with relatively lighter materials, like hay or straw. Several of the other ingredients employed in the compost mix are ash, lime, garden debris like leaves and twigs, and vegetable matter. Most manufacturers produce mass-scale cow dung fertilizer. So, they need sufficient space to permit the pile to obtain enough air.

Many farmers who require cow dung powder fertilizer in small quantities can make exactly the same in their home. Since it doesn’t require excessive heat, the farmer are able to keep the manure beneath a shade and keep twisting and turning it to provide air. Alternatively, manufacturers producing this fertilizer in big amounts use composting machines that mix the ingredients in equal quantities. They could control the temperature as well as twist and turn the manure periodically.

This is amongst the most inexpensive fertilizers in the agricultural sector. But, it will help to produce a high-quality crop, and that’s why most farmers apply it widely all over the world.

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 to make organic fertilizer granules by drum granulation equipment?
