The Utilization of Pig Manure
Pig manure contains 15% organic matter, 0.5% nitrogen, 0.5-0.6% phosphorus, and 0.35-0.45% potassium. Pig manure has a fine texture and complex composition, including protein, fat, organic acid, cellulose, hemicellulose and inorganic salts. Because of the high nitrogen content, the carbon to nitrogen ratio is relatively small, about 14:1, which is generally easily decomposed by microorganisms, releasing nutrients that can be absorbed and utilized by crops.
Pig manure contains the highest humus, the highest yang substitution, the strongest fertility, but the water content is more, the cellulose decomposition bacteria are less, and a small amount of horse manure is mixed to inoculate the cellulose decomposition bacteria, which can greatly increase the fertilizer efficiency.
