Application of traditional organic fertilizer Application of traditional organic fertilizer has a long history. Up to now, it is still the main method of applying base fertilizer in autumn and winter in most orchards. The common methods in production are compost, chicken manure, cow manure, pig manure, sheep manure and other animal manure and human manure. Among them, sheep dung is a natural green fertilizer, containing 4%~27% organic matter, more than other animal dung, rich in nitrogen, phosphorus and potassium nutrition, fine dung and thick fertilizer, belonging to thermal fertilizer. Chicken dung contains rich nutrients, especially the crude protein in chicken dung, with the content of organic matter reaching 25.5%. It can become a better green organic fertilizer through proper processing and utilization.
