Fertilizers that produce high temperatures in the process of accumulation are called hot fertilizers. For example, horse manure has a large amount of heat when it is decomposed, so it is a thermal fertilizer. Sheep manure and rabbit manure are also thermal fertilizers. Organic fertilizers that are not fully fermented and decomposed are basically hot fertilizers, and thermal fertilizers are most suitable for seedling nursery beds.
Low-calorie farmyard manure is a cold fertilizer in the process of accumulation. For example, cow manure decomposes slowly with low calorific value and does not produce high temperatures. Therefore, it is a cold fertilizer and pig manure is also a cold fertilizer. In addition, sheep manure can be considered as a warm fertilizer because its calorific value is between horse dung and cow dung.
The use of hot and warm fertilizers must be fermented and decomposed when they are used. Otherwise, they should not be used in large amounts near the roots of the crop. The hot fertilizer has high cellulose content, loose pores, easy evaporation of water, low water content, and a lot of fiber bacteria in the feces, which can promote the decomposition of cellulose, and can produce high temperatures above 50°C in the stacking process. This type of fertilizer These are collectively called thermal fertilizers. Such as: horse manure, sheep manure, silkworm manure, poultry manure, straw compost and so on.
After the cold-fertilizer is used, it is generally not reheated in the soil, and basically it will not be burned (it is recommended that it be used after fermentation), such as cow dung and pig dung. Its characteristics are detailed texture, more water, slow decomposition, decomposition is more difficult; should be used for sand soil, not only conducive to the decomposition of fertilizer decomposition, but also improve soil water and fertilizer performance, generally used as base fertilizer.
