Application of organic fertilizer after ripening or not

The ripening of organic fertilizer changes in two aspects through the activities of microorganisms: on the one hand, the decomposition of organic matter increases the effective nutrients in the fertilizer; on the other hand, it makes the organic matter in the fertilizer change from hard to soft. the texture changed from uneven to uniform, and most of the weed seeds, germs and insect eggs were killed in the process of ripening, which was more in line with the requirements of agricultural production. Most of the nutrients of organic fertilizers rich in organic matter are delayed, and crops can not absorb and use them directly. if unmature organic fertilizers are applied to the soil, not only the fertilizer efficiency is poor because of slow decomposition, but also breed weeds and spread germs, insect eggs and so on. Therefore, in agricultural production, the way of accumulation is often taken before application to make the farm manure mature. Ripening can also make farm manure release nutrients, improve fertilizer efficiency, and avoid some adverse factors for crops when the fertilizer is rotten in the soil. Such as competing with seedlings for water and nutrients, or burning seedlings due to local high temperature, high ammonia concentration and so on. Therefore, only mature organic fertilizers can significantly improve soil properties.
