Organic fertilizer, as an important fertilizer resource, plays an irreplaceable role in agricultural production. Proper use of organic fertilizers can not only improve soil fertility, improve soil structure, promote crop growth, but also reduce the amount of chemical fertilizers used, lower agricultural production costs, and protect the ecological environment.

In the process of using organic fertilizers, we need to pay attention to the following points: firstly, we need to recognize that the nutrients in organic fertilizers are not omnipotent, and it is necessary to reasonably mix chemical fertilizers and other fertilizers according to crop needs; Secondly, raw feces cannot be directly placed on the ground and must undergo fermentation treatment to kill bacteria, insect eggs, and weed seeds, and avoid problems such as burning seedlings; Thirdly, understand the characteristics of slow decomposition and delayed fertilizer efficiency of organic fertilizers, and arrange fertilization time and methods reasonably; The fourth is to follow the taboos of using organic fertilizers and avoid mixing them with alkaline fertilizers and nitrate nitrogen fertilizers.

At the same time, we need to master the correct use of organic fertilizers. Reasonably combining the use of organic and chemical fertilizers, complementing each others strengths and weaknesses, and improving fertilizer efficiency; It is not advisable to apply a large amount of organic fertilizer in a concentrated manner. The appropriate fertilization location should be selected based on the growth of crop roots; Apply organic fertilizer after sufficient decomposition to reduce the occurrence of pests and diseases and the harm to crops; Scientific application of organic fertilizers, including crop fertilization, application after maturity, with a focus on basal and deep application, controlled fertilizer application, and reasonable mixed application; Apply organic fertilizer as base fertilizer, topdressing, seedling fertilizer, and nutrient soil to fully utilize its different functions; Improve the effectiveness of organic fertilizer application through methods such as composting raw manure, using it as base fertilizer, trenching, and spreading.

In short, only by correctly understanding and mastering the usage methods and precautions of organic fertilizers can we better play the role of organic fertilizers and contribute to agricultural harvest and ecological environment protection. Let us actively promote the correct use of organic fertilizers and promote sustainable agricultural development.
