How Should Organic Fertilizer be Composted

Pile the farmyard manure by 30-40cm, sprinkle calcium superphosphate evenly on each layer, and sprinkle 10% urea aqueous solution or live bacterial agent dilution. This pile to 5-7 layers, the height of the fertilizer pile to 1.5 m to 2 m is appropriate, to be stacked, the surface of the pile with soil (3-4 cm) or plastic sheeting to seal the fertilizer pile. To heat insulation and moisture, hinder the entry of air, to prevent the loss of fertilizer and water evaporation. High summer temperatures, peritoneal composting takes about 20-30 days, spring and autumn composting are required 2-3 months (if the use of "BTEM live bacteria, HM bacteria, straw rotting spirit, CM bacteria decay agent, enzyme bacteria," etc. can be reduced by half the time).

Composting points: summarized as "drink enough, eat enough, cover tightly, turn the pile".

Drink enough: Refers to the composting of farm fertilizer must be fully wet, to manure is not flowing water is appropriate, (hold tightly muffled fertilizer material from the fingers of water extrusion that indicates that the water content of roughly the right amount). This is the key measure of fermentation and decomposition.

Eat full: 10-15 kilograms of calcium superphosphate per square of farmyard manure mixed, if the fertilizer preparation is not timely, need to speed up the fermentation, 1-2 kilograms per square of farmyard manure with 1-2 kilograms of "BTEM live bacteria agent" strain, first dilute the strain with clean water (if the water content of the fertilizer source is high dilution concentration, and vice versa is low), and then sprinkle the bacteria water on the farmyard manure. Mix evenly while sprinkling.

Cover tightly: To keep water, heat preservation and fertilizer.

Turning pile: In the process of pile covering, when the temperature of the pile heart reaches 70 ℃ to turn the pile in time, can prevent the temperature is too high to kill the biological bacteria, help to maintain the activity of the strain of bacteria, so that the fermentation more fully.

 Ripening standard: Color is dark brown; no bad smell, even slightly aromatic smell or ammonia smell; can not see the shape of the original pile, for pulling and pinching very easy to break, water content increased; compost is neutral to slightly alkaline, carbon and nitrogen ratio reduced to less than 20.
