When applying organic fertilizers, comprehensive consideration should be given to soil conditions, crop demand, and local resource conditions. Although livestock and poultry manure is rich in nitrogen, phosphorus, potassium, and trace elements, attention should be paid to the possible presence of heavy metals and pathogenic bacteria. It must be treated harmlessly before use; Crop straw and green manure are more suitable for improving soil structure and increasing soil organic matter content. Here are some common precautions:

Avoid excessive use: Although organic fertilizers are beneficial for soil and crops, excessive use can also lead to nutrient excess, affect crop growth, and even cause environmental pollution. Therefore, the application amount should be reasonably determined based on soil testing results and crop demand.

Fully decomposed: Untreated organic fertilizers may contain harmful substances such as bacteria and insect eggs, and direct application can harm crop health. Therefore, it is necessary to ensure that the fertilizer has fully decomposed before use. Collaborative application: Organic fertilizers and chemical fertilizers have their own advantages and disadvantages, and reasonable combination can complement each others strengths and improve the effectiveness of fertilization. For example, adding organic fertilizer to the base fertilizer and applying an appropriate amount of chemical fertilizer based on crop growth. Combination of fertilization and irrigation: After fertilization, timely irrigation should be carried out to promote fertilizer dissolution and root absorption. But it is also necessary to avoid flooding to prevent nutrient loss.
