Organic fertilizers are made by fermenting various household fertilizers. More commonly used are chicken manure, cow manure, and pig manure. Among them, chicken manure is more suitable for fertilizer, but the effect of cow manure is relatively poor. Fermented organic fertilizers should pay attention to carbon-nitrogen ratio, moisture, oxygen content, temperature, and pH. We will describe them in detail below:
1. Chicken manure is an organic fertilizer, and the fertilizer efficiency of the three fertilizers is higher, but the nitrogen in chicken manure cannot be directly absorbed by plants. If applied directly to the field, it will cause plant death. This is because chicken manure contains uric acid, which inhibits the growth of crop roots. Chicken manure, on the other hand, is high in organic matter and fermented in the field generates heat and damages plant roots. Therefore, chicken manure must be fully fermented and decomposed before being used as organic fertilizer. However, poultry manure is easy to decompose and the decomposing temperature is relatively high. It belongs to thermal fertilizer. Using poultry manure as raw material, it ferments and decomposes quickly, and can be made into fertilizer with high nutrients. It is a very good raw material for composting.
2. Pig manure is the milder organic fertilizer among the three. Pig manure has high nitrogen content but also relatively large water content, among which the organic matter is relatively medium and easy to decompose. It breaks down rapidly during ripening. Pig manure contains a lot of humus, which can not only save nitrogen, phosphorus, potassium fertilizers in the soil, but also further improve: the soil structure is conducive to the retention of water and fertilizer in the soil, but pig manure also contains many bacteria and harmful organisms before normal use needs to be broken down.
3. Cow dung has the poorest fertilizer efficiency among the three, but it is the mildest. The organic matter is more difficult to decompose, decomposes slowly, and the fermentation temperature is low. Because the cattle feed mainly on forages, the cow dung contains cellulose. Mainly, the content of natural nitrogen, phosphorus, and potassium is low, and it will not cause excessive fertilizer effect and harm to plants when applied to the field, but the cattle will contain a lot of grass seeds during the process of grazing. If they are not decomposed, the grass seeds will be in the field. Rooted and sprouted.
4. Sheep manure is fine in texture and low in water content, and its nitrogen form is mainly urea nitrogen, which is easy to be decomposed and utilized.
5. Horse manure has a high content of organic matter, and also contains a lot of fiber-decomposing bacteria, which can generate high temperatures during composting.
