In everyone's impression, the use of fertilizers, which are commonplace in agricultural production, is an important measure to increase crop yields, but many people do not see the harm caused by fertilizer abuse. Generally speaking, the most applied amount in agricultural production is nitrogen fertilizer. If the application of nitrogen fertilizer exceeds the absorption of crops, it will cause a series of bad “reactionsâ€, such as nitrogen pollution and soil acidification. Therefore, from the perspective of sustainable agricultural development, agricultural fertilization should pay attention to scientific application and balanced fertilization. The application of soil instruments such as soil nutrient rapid tester can promote the level of agricultural fertilization and achieve the goal of weight loss and efficiency.
Fertilizing the soil is actually to return the nutrients taken from the soil to the soil and maintain the soil fertility. This is the meaning of fertilization. To achieve scientific fertilization, understanding the soil nutrient status is the most basic requirement, because the fundamental application of fertilization is to supplement the soil nutrient deficiency, and then know what needs to be supplemented and how much to make up. In many areas of scientific fertilization activities, the soil nutrient speed measuring instrument is the most basic testing instrument. The instrument measures and analyzes the soil nutrient content through technical means, and provides a scientific basis for soil testing and formula fertilization in the agricultural field, and promotes precision. Fertilize.
Long-term planting experience also shows that the more soil fertilization, the more fertile the soil, the higher the crop yield. To increase production and income, it must be applied according to the crop growth needs and the actual nutrient content of the soil. The effect of fertilization is not good. The problem is not in the fertilizer itself, but in the method of application. Soil nutrient speed measuring instrument is used to measure soil, and soil testing and formula fertilization is carried out. It is a kind of modern agriculture to carry out scientific fertilization to achieve cost-effectiveness. An effective measure. Through instrumental guidance, the level of agricultural fertilization has been significantly improved, and the quality of agricultural production is also more secure.
