Soil testing and formula fertilization is a complex system engineering. It is necessary not only to consider the characteristics of the soil and the needs of the crop, but also to consider the carrying capacity of the environment, the quality of the crop, and the method of fertilizer application and the level of knowledge of the application personnel. In balanced fertilization, not only efficient soil nutrient testing techniques and equipment are needed, but also fertilizer products that are compatible with them are needed. Several are indispensable. China's high-grade phosphorite resources are relatively small. In the long term, low-level phosphate fertilizers will become the main force for China's plant phosphorus nutrition.
At present, large quantities of high-concentration compound fertilizers are pouring into the market. However, due to the fixed nutrient ratio of compound fertilizers, it is difficult to apply reasonable fertilizers, which also results in the waste of effective fertilizer nutrients.
Increase the intensity of soil testing and fertilization, so that people have a clear understanding of the connotation of soil testing and formula fertilization, and earnestly train farmers to understand the basic principles of plant nutrition, master scientific fertilizer technology, truly missing what, make up What is missing, how much, how much. The prospect of simple low-concentration fertilizers is still very broad. At the same time, low-concentration fertilizers can take full advantage of low-grade phosphorus resources, and farmers in most areas have the advantage of applying superphosphate and calcium magnesium phosphate fertilizers. Utilizing the nutritive effects of the non-nutrient components of your fertilizer, ie nutrients, silicon, magnesium, and calcium that are not recorded in nutrients, is also an advantage of low-concentration fertilizers.
In theory, soil testing and formulating fertilization can be based on the nutrient content in the soil and the amount of nutrient elements required by the crop, so that the nutrients needed for the crop can be properly applied. If the elemental fertilizer does not contain harmful ingredients, regardless of the nutrient concentration, as long as the application amount is reasonable, it can meet the requirements of high yield and high quality of the crop. It should be noted that low nutrient concentrations of low-level fertilizers increase transport and application costs.
