1. Pig manure Pig manure is rich in nutrients, potassium content is highest, and nitrogen and phosphorus content is second only to sheep manure. The texture of pig feces is finer, ammoniated bacteria are more easily decomposed, and the fertilizer efficiency is quicker, which is conducive to the formation of humus and has a good effect on soil improvement. The pig manure is soft and has a strong stamina. It is a warm fertilizer. Suitable for a variety of crops and soils, decomposed pig manure can be used in paddy fields, can also be used for dry soil, can be used as base fertilizer, can also be used as fertilizer.
2. Cow dung Cow dung has fine texture, high water content, poor ventilation, slow decomposing, slow fertilizer effect, low fermentation temperature, and is a cold fertilizer. In order to accelerate the decomposition, fresh cow dung can be dried slightly, and horse dung or sheep dung can be mixed and stacked to obtain high quality fertilizer. Such as mixed with calcium magnesium phosphate or phosphate rock, fertilizer quality is higher. Cow dung has high carbon content, low nitrogen content, and a large carbon-nitrogen ratio. Attention should be paid to the use of available nitrogen fertilizers during application to prevent nitrogen from composting between microorganisms and crops during fertilizer decomposition. Cow dung is generally used only as base fertilizer.
3. Horse manure Horse dung has high fiber content, thick manure, loose pores, easy evaporation of water, low water content, rapid decomposing, large heat and high temperature during the accumulation process, and is a thermal fertilizer. Can be used for nursery seedlings, heat effect is better than pig dung. When composting, adding appropriate amount of horse dung can promote compost maturity. Due to the coarse texture of horse dung, it is particularly suitable for sticky soils and can be used as a modifier for sticky soils.
4. Sheep feces sheep manure nitrogen, calcium and magnesium are higher. Sheep feces fever is between horse dung and cow dung. Sheep manure is suitable for all kinds of soil and all kinds of crops, and the effect of increasing yield is good. After decomposing, it can be used as base fertilizer, top dressing and seed fertilizer.
5. Rabbit feces rabbit feces in the nitrogen and phosphorus content is relatively high, potassium content is relatively low. The rabbit's fecal carbon-nitrogen ratio is small, it is perishable and decomposes quickly when applied to soil, and it is a thermal fertilizer. It is better to use on phosphorus-deficient soil.
6. Poultry Manure contains higher nutrient content than livestock manure. Chicken manure also has the highest nutrient content in poultry manure. Poultry manure decomposition process is easy to produce high temperature, is a thermal fertilizer. Poultry excrement can easily incur underground pests, and uric acid nitrogen cannot be directly absorbed and utilized by crops and must be fully decomposed before application. Poultry manure is best used as top dressing.
