Useful Value of Pig Manure

Pig manure:

The pig manure has fine texture and contains more organic matter and nitrogen, phosphorus and potassium nutrients. The pig manure is slower to decompose and is suitable for base fertilizer. The pig manure can increase the yield of 200-300 kg of grain. Pig manure contains 15% organic matter, low total nutrient content, nitrogen 0.5-0.6%, phosphorus 0.45-0.5%, and potassium 0.35-0.45%. Pig manure has a fine texture and complex composition, including protein, fat, organic acid, cellulose, hemicellulose and inorganic salts. Pig manure contains more nitrogen and has a smaller carbon to nitrogen ratio (14:1). It is generally prone to decomposition by microorganisms and releases nutrients that can be absorbed and utilized by crops.

 

Benefits: After the fermented pig manure is fully decomposed, it will not be subjected to secondary fermentation, which will prevent the burning of the roots and burn it more safely. The fermentation process will also break down the macromolecular organic matter contained in the pig manure into crops. It can directly utilize inorganic salts and minerals, and produce bacterial metabolites; the fermentation process is also a biological deodorization process, and the fermented pig manure fertilizer has no odor and is more convenient to use.

 

Precautions:

(1) Nitrogen is easily decomposed, and proteins, urea, amino acids, uric acid, etc. are converted into ammonium salts and nitrates, which are easily decomposed and lost.

(2) The phosphorus content is high, and the phosphorus-containing compound is easily converted into phosphoric acid and phosphate under the action of microorganisms.

(3) Potassium is mostly water-soluble potassium, which is easily absorbed by crops.

(4) When accumulating, it is necessary to add a bedding material. Commonly used soil or grass charcoal, the ratio of soil to fertilizer is better than 3:1.

(5) It is forbidden to pour the ash into the circle to avoid the loss of nitrogen volatilization.
