Application of Traditional Organic Fertilizer

Application of traditional organic fertilizer has been a long time, so far is still the main practice of most orchards in the fall and winter application of fertilizer, production is commonly used compost, chicken manure, cow manure, pig manure, sheep manure and other livestock manure and human manure and urine.　　

Among them, sheep manure is a natural green fertilizer, containing 4% to 27% organic matter, more than other livestock manure, rich in nitrogen, phosphorus and potassium nutrients, fine manure, thick fertilizer, a hot fertilizer. Chicken manure is rich in nutrients, especially the crude protein in chicken manure is more, organic matter content reaches 25.5%, through appropriate processing and utilization can become a better green organic fertilizer. Pig manure contains 15% organic matter, the total nutrient content is not high, the carbon to nitrogen ratio is small (14:1), and it is easier to be decomposed by microorganisms, releasing nutrients that can be absorbed and used by crops. The organic matter content of cow manure is 14.5%, and the air-dried sample contains 43.6% crude fiber and close to 1% nitrogen, phosphorus and potassium.　　

Due to the large amount of traditional organic fertilizer per mu, the application requires deep digging and deep burial, labor intensity, which seriously affects the enthusiasm of fruit farmers to apply base fertilizer in autumn and supplement the soil organic matter. Together with the current orchard production staff is getting older, the application of traditional organic fertilizer has been a great challenge, affecting the sustainable production of orchards.
