Soil testing and formula fertilization is based on soil testing and fertilizer field trials. Based on the soil nutrient supply performance, crop fertilizer requirements, and fertilizer effects, based on the rational application of organic fertilizers, the appropriate proportions of nitrogen, phosphorus, potassium and trace elements are proposed. Dosage, and corresponding fertilization techniques, to meet the crop's balanced absorption of various nutrients, to achieve the balance of the three elements of NPK, organic and inorganic nutrient balance, balance of large amounts of elements and trace elements, maintain soil fertility levels, reduce nutrient loss and Environmental pollution, to achieve high yield, quality and efficiency.
There are three main benefits of soil testing and formula fertilization: 1. It can reduce fertilizer waste. If you do not measure soil, you do not know how much nutrients the soil contains, and blind fertilization will result in waste of fertilizer. 2, can increase crop yields. Soil testing and formula fertilization can meet the needs of crop growth, making the crop more resistant to disease and stress, thereby increasing crop yield. 3, can improve the quality of agricultural products. The use of soil-based formula fertilization and reasonable fertilizer application can reduce the accumulation of nitrogenous fertilizer in the soil and reduce the content of harmful substances. In addition, it can meet the different fertilizer requirements of different crops and improve crop quality.
According to the sample survey, different soil types and different crops have different soil nutrients, and the proportion of nutrients is seriously out of balance. To solve these problems, we must implement soil testing and formula fertilization.
