In agriculture, whether it is a vegetable or a fruit tree, three kinds of fertilizers, chicken manure, cow dung and pig manure, are used. These three kinds of fertilizers are organic fertilizers of different nature. For example, chicken manure is a hot fertilizer, and cattle. The manure is cold, and the pig manure is warm. Which kind of fertilizer should be used normally? We will comprehensively compare and analyze these three kinds of fertilizers from the perspective of nutrient and so on today. 1. Comparison of nutrients: From the comparison of nutrient content, the organic matter content of chicken manure exceeds 25%, and the organic matter content of pig manure and cow dung is generally 15%. Among them, chicken manure has the highest nitrogen, phosphorus and potassium content, so the nutrient content is also the highest, from the perspective of nutrient. In terms of chicken manure, it is the best. Cow dung is the least organic matter and nutrient content. It is not difficult to explain that both chicken and pigs use more feed, which contains more organic matter, while cow dung is mainly grass, and the feces are mainly cellulose. And nutrient content is not much. 2. Comparison of other angles: In the process of breeding chicken manure, more antibiotics are used, pigs are used less, cows are more difficult to get sick, and antibiotics are less. The order of antibiotics and heavy metals is chicken manure, pig manure and cow dung in order of high to low. However, as long as the organic fertilizer is fermented by factory fermentation, antibiotics and heavy metals generally do not exceed the national limit. From the above comparison, the nutrient of chicken manure is the most best of the three fertilizers. However, in general, chicken manure and pig manure on the farm are recommended for factory-based pollution-free decomposing and reuse, and cow dung can be directly composted and decomposed. The decomposed chicken manure and pig manure can be used in greenhouse orchards, etc., which can be used to supplement organic matter. If cow dung is used, it can be used on some field crops to improve soil.
