Post composting management
Generally, 3-5 days after compost, organic matter begins to be decomposed by microorganisms to release heat, and the temperature in the heap rises slowly.After 7-8 days, the temperature in the reactor increased significantly, reaching 60-70 ℃.High temperature easily leads to the lack of water in the reactor, which weakens microbial activity and incomplete decomposition of raw materials.Therefore, during the stacking, the moisture and temperature changes in the upper, middle and lower parts of the heap should be checked frequently.Check method: use compost thermometer to test.If no compost thermometer is available, insert a long iron bar into the heap and leave it there for 5 minutes.The temperature of the hand is about 30℃, the heat is about 40-50 ℃, and the heat is about 60℃ or more.
Check the moisture content to observe the dry and wet condition of the inserted parts.If it is wet, it means appropriate amount of water;If it is dry, it means there is too little water.If the moisture and ventilation in the reactor are adapted, the temperature will rise gradually in the first few days and reach the maximum in about a week.Maintain high temperature stage, not less than 3 days, l0 days after the temperature slowly decline.In this case, after 20-25 days to turn the heap once, the outer layer turned to the middle, the middle turned to the outside, according to the need to add an appropriate amount of excrement and urine water re accumulation, promote the rot.After the re - accumulation, and 20-30 days, raw materials have been nearly black, rotten, smelly degree, indicating that the basic rot.You can use it, or keep it tightly covered.
Composting can be used in our
Organic Compost Turning Machine. Composting is the first step of organic fertilizer production. After composting, the manure is pelleted through the
organic fertilizer production line.Can also be directly through the
organic fertilizer powder production line, directly used, without granulation.Whether organic matter is granulated or not, our
organic fertilizer production equipment can help you turn animal waste into money.

Inspection criteria for composting ripeness
Composting maturity is a comprehensive index to identify the quality of compost.It can be judged by its color, smell, straw hardness, compost leach, compost volume, carbon nitrogen ratio and sapropelization coefficient.
Ripe pig manure organic fertilizer
(1) color and odor: the straw of decayed compost turns brown or black brown, has black juice and has ammonia odor. The ammonium nitrogen content is significantly increased by using ammonium reagent.
(2) straw hardness: holding compost by hand, soft and elastic when wet;It is brittle and brittle when dry, and the organic matter loses its elasticity.
(3) the leaching liquid of compost: take the decaying compost, stir it with water (proportion of fertilizer and water 1:5-10), leave it for 3-5 minutes, and the leaching liquid is light yellow.
(4) compost volume: 2/3-1/2 smaller than when the compost was first piled.
(5) carbon nitrogen ratio: generally 20 -- 30:1.
(6) humus coefficient: about 30%.
The compost which can reach the above targets is high quality compost with good fertilizer efficiency and can be applied to all kinds of soil and crops.Stick to long-term application, not only can make plants grow healthily and get high yield, but also have remarkable effect on soil improvement and soil fertility improvement.
