Choose suitable organic fertilizers. There are many types of organic fertilizers, including animal manure (such as cow manure, sheep manure), plant residues (such as straw, green manure), compost, cake fertilizer, etc. Different types of organic fertilizers have different nutritional components, release rates, and are suitable for different crops.

Choosing suitable organic fertilizers requires comprehensive consideration of crop needs, soil conditions, and climate conditions. For example, for acidic soils, lime based organic fertilizers (such as plant ash) can be added in moderation to neutralize the acidity; For nitrogen loving crops such as leafy vegetables, one can choose soybean cake fertilizer with high nitrogen content or thoroughly decomposed animal manure; For orchards or vegetable gardens that need to improve soil structure, composting is an ideal choice because it can increase soil organic matter content, improve soil particle structure, and ensure reliable sources of organic fertilizers, avoiding the use of fertilizers containing heavy metals or other harmful substances.
