The results of the soil fertilizer tester can be found that excessive use of chemical fertilizers, a large number of NH4, K+ and soil colloids adsorbed Ca2+, Mg2+ and other cations exchanged, so that the soil structure is destroyed, resulting in soil compaction. Extensive application of chemical fertilizers, land useless, resulting in a decline in soil organic matter, fertilizer can not compensate for the lack of organic matter, further affected the survival of soil microorganisms, not only undermined the soil fertility structure, but also reduced the fertilizer effect. Mineral raw materials and chemical raw materials for chemical fertilizers contain many kinds of heavy metal elements, radioactive substances and other harmful components. They enter the farmland soil as a result of fertilization and cause pollution. In recent years, soil pollution has become increasingly serious and has affected the nutritional value and tolerance of agricultural products. Storage, resistance, and thus affect the human health. This point is confirmed in modern medicine, clinically related diseases are also gradually appearing, and people's lives are also the most direct experience.
The soil fertilizer detector measures the long-term use of N, P, and K in soil nutrients and finds that NPK nutrients have a considerable destructive effect on the soil structure, resulting in imbalance of soil nutrients, loss of nutrients, and increased pollution. This requires that in future production practices, we should balance scientifically formulated fertilization, combined use and maintenance, and vigorously implement/measure, match, produce, supply, and implement integrated agrochemical services based on different crops and soil types. Improve the soil structure, fertilize the soil, increase the absorption and utilization of chemical fertilizers and organic fertilizers, and maintain the use of land for long periods of time. This will not only save production costs, increase crop yields and improve product quality, but also protect the agricultural ecological environment, thus improving agricultural products. Quality, and truly increase the number of agricultural products, can also achieve high yield, stable production, high quality, high yield, high quality and high efficiency. It lays a solid foundation for the sustainable development of agriculture.
