How To Process Cow Dung Into Organic Fertilizer
In fact, cow dung has many uses. It can be used as a raw material for biogas, can be used to produce organic fertilizer, and can also be used as a culture material for the production of Agaricus bisporus and earthworms raising, etc. So can cow dung be processed into organic fertilizer? How to process organic fertilizer from cow dung? Let’s find out.
Cow dung processing organic fertilizer technology
In order to turn cow dung into organic fertilizer, the following steps are required. First, the cow dung should be dried or drained to keep its moisture content below 85%, and then straw is added. The ratio of cow dung and straw is 7: 3. The carbon ratio of raw materials (cow dung) and auxiliary materials (straw ends) should be controlled at 23:28, and the water content should be controlled at 52%-68%. Then add organic fertilizer fermentation decomposing agent. After the raw materials, auxiliary materials and inoculants are mixed and stirred, they can be stacked and fermented. The requirement of stacking is to stack the mixture on the fermentation field into a bottom width of 1.8-3 meters, a top width of 0.8-1 meters, and a height of 1-1.5 meters. Trapezoidal stacks, with an interval of 0.5 meters between stacks. Go here to know more about cow manure composting
After the cow litter materials are stacked, the temperature will rise to above 60°C within 24-48 hours, and the temperature will be maintained for 48 hours to start the stacking. Because it is a aerobic fermentation, you need to be sure to turn the pile evenly and thoroughly, and turn the low-level special materials into the middle and upper part of the pile as much as possible, so as to decompose. After the first turn over, turn over once a week thereafter. However, when the temperature exceeds 70 ℃, it must be turned over immediately, otherwise the beneficial microorganisms and fermenting bacteria will be killed in large quantities, which is not conducive to fermentation and decomposing. In order to make this process easily, SX can provide you with professional compost machines for cow dung processing.
Fermented and decomposed cow dung standards:
- First, look at the color. Generally, the color of fertilizers will turn brown or dark brown, and the ammonium nitrogen content will increase significantly.
- The second is to look at the leachate. After mixing the decomposed organic fertilizer with water (1:5), let it stand for 5 minutes to see the color of the leachate.
- The third is to look at the volume. The volume of decomposed compost is 1/3-1/2 smaller than that of the newly piled stack. , Spread the fermented organic fertilizer evenly on the drying field, the thickness should not exceed 20 cm, and often turn over to make the water content less than 32%.
