What is soil testing and formula fertilization?
What we call soil testing and formula fertilization is the internationally known balanced fertilization. This technology is the advanced agricultural technology that the United Nations promotes around the world. In summary, the first is to measure the soil, take the soil sample to determine the soil nutrient content; the second is the formula, after the nutrient diagnosis of the soil, according to the nutrients needed for crops, “prescribe the prescription and the prescription according to the prescriptionâ€; the third is the rational fertilization, that is, Scientific application of formula fertilizer under the guidance of agricultural science and technology personnel.
Why do you need to implement soil testing and formula fertilization?
This is about the relationship between crops, soil and fertilizer. The roots of crop growth are in the soil, and plant nutrients are absorbed from the soil by 60%~70%. There are many kinds of soil nutrients, which are mainly divided into three categories: the first category is nitrogen, phosphorus and potassium, which are relatively low in soil and have a large amount of absorption and utilization of crops. The second category is that the soil content is relatively high, but the crops need less, such as silicon, sulfur, iron, calcium, magnesium, etc., called medium-quantity elements. The third category is that there is little soil and little crops, mainly copper, boron, manganese, zinc, molybdenum, etc., called trace elements. These nutrients contained in the soil are essential for the growth and development of crops. When the soil nutrient supply is insufficient, it is necessary to supplement it by fertilization to achieve the balance between fertilizer and crops.
What is the content of soil testing and formula fertilization?
Soil testing is based on the diagnosis of the soil, analysis of crop fertilizer requirements, mastering the characteristics of soil fertilization and fertilizer release related conditions, determine the type of fertilizer applied, the proportion of fertilizer, and the fertilizer.
In a broad sense, it should include the application of agricultural fertilizers and fertilizers. Here, a metaphor can be used to supplement soil nutrients, apply fertilizer to fertilizer ratio as “food supplementâ€, and apply fertilizer to “medicine supplementâ€. People often say that “food supplement is better than medicine supplement†because farmyard manure contains a lot of organic matter, which can increase soil aggregate structure, improve soil water, fertilizer, gas and heat, and not only can supplement nitrogen, phosphorus and potassium in soil. Large elements can complement various medium and trace elements. Practice has proved that the combination of farmyard manure and chemical fertilizer can increase the fertilizer utilization rate by 5%~10%.
