Direct application is not worth the loss The unfermented and fertilized raw sheep manure has little effect on improving soil and fertility, and it will bring serious adverse consequences after application, which is not worth the loss. Sheep manure contains pathogens and pests such as coliforms and nematodes. If it is used directly, it will lead to the spread of pests and diseases, crops, and burns and burns. Therefore, sheep manure needs to be fermented to be safer. Not only sheep, but also all kinds of livestock, including human dung, contain a large number of germs, eggs and parasites. Unfermented manure cannot be directly applied to crops. Choose fermented and thoroughly cooked fertilizer The fermentation process of sheep manure will dissipate most of the heat. If it is not fermented directly, it will easily cause the burning of plants and burning of seedlings. The nitrogen fertilizer in the sheep manure begins to exist in the form of protein. The plant cannot directly use the protein, and only after the fermentation, the protein is decomposed into ammonia to be used by the plant. The majority of farmers must choose fermented and thoroughly cooked organic fertilizer or bio-organic fertilizer. Do not apply unfertilized sheep manure (sheep board manure) because of the cheaper figure to avoid undue loss. Disclaimer: Some articles on this website are transferred from the Internet.
