Tips of Application of Cow Dung

Cow manure is slow and is a “cold fertilizer”. Fresh cow manure contains 83.3% water content, organic matter 14.5%, nitrogen 0.32%, phosphorus 0.25%, potassium 0.16%, dry matter 22.56%, crude protein 3.1%, crude fat 0.37%, crude fiber 9.84%, nitrogen-free extract. 5.18%, calcium 0.32%, phosphorus 0.08%. The air-dried sample contained 13.74% crude protein, 1.65% crude fat, 43.6% crude fiber, 22.94% nitrogen-free extract, 1.40% calcium, and 0.36% phosphorus.


Benefits: The use of cow dung as a raw material to produce organic fertilizer, the cost is small, the quality is relatively stable. The fermentation speed of cow dung is fast, and the process of complete deodorization, fermenting and sterilization, and insecticidal sterilization of cow dung can be completed in about 7 days. Fermented organic fertilizer, good fertilizer effect, safe and convenient to use, will not cause burnt roots, can also fertilize soil and improve fertilizer utilization.



(1) Cow manure should be added to the straw, grass, peat or soil and other gaskets, absorb the urine, add horse manure, sheep manure and other hot manure to promote the cow manure decomposing.

(2) Add calcium, magnesium and phosphate fertilizers during composting to increase nitrogen and phosphorus, and improve the quality of fertilizer. At the same time, it should be smeared about 7 cm in the outer layer of compost.

(3) The decomposed cow dung should be used as the base fertilizer, and it should be applied when the whole land is smashed. It must be applied after maturity to ensure the conversion of nutrients and the elimination of germs and eggs.

(4) It should not be mixed with alkaline fertilizers, such as ammonia water, ammonium hydrogencarbonate, etc.
