Manure is rich in organic matter and various nutrients required by crops, which has a good effect on increasing crop yield and improving soil fertility, and has been widely used in agricultural production. However, in recent years, the irrational use of manure has also increased significantly. If manure is used in the wrong place, it will not only have a good effect, but also backfire. Let’s briefly introduce it today.
Main components of various livestock manure:
Pig dung
Pig manure contains 15% organic matter, 0.5% nitrogen, 0.5~0.6% phosphorus and 0.35~0.45% potassium. Pig dung has a fine texture and complex composition, including protein, fat, organic acid, cellulose, hemicellulose and inorganic salt. Due to the large amount of nitrogen, the proportion of carbon and nitrogen is small, about 14:1. Generally, it is easy to be decomposed by microorganisms and release nutrients that can be absorbed and utilized by crops. Pig manure has the highest humus content, the largest amount of cation exchange, and the strongest fertility retention, but it has more water content and less cellulosic decomposing bacteria. Mixing a small amount of horse manure to inoculate cellulosic decomposing bacteria can greatly increase fertilizer efficiency.
cow dung
Cow dung contains 14.5% organic matter, 0.30~0.45% nitrogen, 0.15~0.25% phosphorus and 0.10~0.15% potassium. The content of organic matter and nutrients is relatively low among all kinds of livestock, with fine texture, high water content, slow decomposition and low calorific value, which is a slow-acting fertilizer. Due to its high water content, poor aeration and difficult decomposition of organic matter, cow dung is a cold fertilizer.
Horse dung
Horse manure contains 21% organic matter, 0.4~0.5% nitrogen, 0.2~0.3% phosphorus and 0.35~0.45% potassium. The components of horse dung are mainly cellulose and hemicellulose. In addition, it also contains lignin, protein, fat, organic acid and various inorganic salts. The water in horse dung is easy to evaporate, and contains more cellulolytic bacteria. It is a thermal fertilizer. Applying horse dung can improve the properties of clay.
Sheep dung
Sheep dung contains 24-27% organic matter, 0.7-0.8% nitrogen, 0.45-0.6% phosphorus and 0.4-0.5% potassium. Sheep dung contains more organic matter than other animal dung, which is fine and rich in fertilizer. Sheep dung has a fever between horse dung and cow dung. It is also a thermal fertilizer, also known as thermal fertilizer. It can be applied on sandy soil and clayey soil with good effect.
Bird dung
The poultry manure contains 25.5% organic matter, 1.63% nitrogen, 1.54% phosphorus, 0.85% potassium, 11% carbohydrate, 7% fiber, and fresh poultry manure has a high water content. The nitrogen in poultry manure (chicken manure, duck manure, goose dung, pigeon dung, etc.) is mainly uric acid, which can not be directly absorbed by crops and is harmful to the growth of crop roots. At the same time, fresh poultry manure is easy to attract underground pests.
The organic fertilizer production line uses modern microbial technology, mainly livestock and poultry excrement, and bran, peanut shell powder, crop straw and other auxiliary materials as carriers. The bacteria and livestock and poultry excrement are fully mixed by mixing method, so that the microbial strains are connected to the livestock and poultry excrement, including dehydrator, fermentation turner, semi-wet material crusher, horizontal mixer, granulator, dryer, cooler, drum screening machine, coating machine, packaging equipment The bio-organic fertilizer produced by belt conveyor and other equipment after a series of harmless treatment such as rapid heating, fermentation, ripening and deodorization.
