After different types of manure are processed by organic fertilizer production machine, the nutrient content of organic fertilizer is different. The use of manure depends on the actual situation of your land.
Nutrients of organic fertilizer made from different kinds of feces
1. Pig manure
Pig manure contains 15% organic matter, 0.5% nitrogen, 0.5-0.6% phosphorus and 0.35-0.45% potassium. Pig manure is fine in texture and complex in composition. It contains proteins, fats, organic acids, cellulose, hemicellulose and inorganic salts. Due to the high nitrogen content, the ratio of carbon to nitrogen is relatively small, about 14:1, which 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, but it has more water content and less cellulose decomposing bacteria.
2. Cow dung
Cow manure contains 14.5% organic matter, 0.30-0.45% nitrogen, 0.15-0.25% phosphorus, and 0.10-0.15% potassium. The organic matter and nutrient content is low in all kinds of livestock, with fine texture, more water, slow decomposition, low calorific value, and it is a late-acting fertilizer. Because of its high water content and poor ventilation, cow manure is difficult to decompose organic matter and is a cold fertilizer.
3. Horse manure
Horse manure contains 21% organic matter, 0.4-0.5% nitrogen, 0.2-0.3% phosphorus, and 0.35-0.45% potassium. Horse manure contains more cellulose and hemicellulose. In addition, it also contains lignin, protein, fats, organic acids and various inorganic salts. The water in horse manure is easy to evaporate and contains more cellulolytic bacteria. It is a thermal fertilizer. The application of horse manure can improve the properties of clay. Further processing with disc granulator machine is high-quality organic fertilizer.
4. Sheep dung
Sheep manure contains 24-27% organic matter, 0.7-0.8% nitrogen, 0.45-0.6% phosphorus, and 0.4-0.5% potassium. Sheep manure contains more organic matter than other animal manures, with finer manure and thick fat. Sheep dung heats up between horse dung and cow dung. It is also a thermal fertilizer, also called a warm fertilizer. It is effective when applied on sandy soil and clay soil. It is suitable for organic fertilizer factories to use it as a raw material, which can be processed by rotary drum granulator and organic fertilizer granulator.
5. Poultry manure
Poultry manure contains 25.5% organic matter, 1.63% nitrogen, 1.54% phosphorus, 0.85% potassium, 11% carbohydrate and 7% fiber. The main form of nitrogen in poultry manure (chicken manure, duck manure, goose manure, pigeon manure, etc.) is uric acid. Uric acid 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.
