The use of chemical fertilizers has obvious effects on increasing grain production. This is a positive aspect brought about by chemical fertilizers and deserves our recognition. At the same time, the abuse of chemical fertilizers causes certain problems, that is, it causes certain pollution to the agricultural environment. As a result, soil compaction and quality have declined, and the utilization rate of chemical fertilizers in China has been lower than in developed agricultural countries, resulting in serious waste of resources. As a result, the cost of agriculture has become higher and higher, while the agricultural efficiency has been decreasing. Therefore, in the new stage of agricultural development, the use of soil nutrient testers to promote scientific fertilization is an inevitable development of agriculture, and it is also the key to solving the problem of fertilizer use.
In order to guide the scientific fertilization of large grain farmers or agricultural planters, Topsun Yunnong has introduced a soil nutrient tester. It measures soil nutrients and formulates fertilization according to the needs of different crops. This fertilization operation is more fertilized than previous experience. In contrast, it will be more professional and scientific. It is based on the spatial and temporal distribution of soil, fertilizer, and water resources. It is based on local conditions. It takes into consideration the performance of soil fertilizer supply, fertilizer production, and fertilizer requirements for crops. In the best period, the best method is used. Precise and reasonable fertilization, to fully meet the demand for nutrients at all stages of crop growth, and strive to achieve the highest yield of crops; at the same time with the minimum fertilizer input to obtain the highest economic output, economic benefits are very significant. In addition, according to the soil nutrient tester's measurement data, through the scientific, rational and efficient fertilization, fertilizer application is appropriate, and the environmental protection function of fertilization is exerted. Not only can the yield benefit be improved, but also the negative impact of fertilization on the environment can be reduced, thus improving the soil. Improve the quality of the environment.
In agricultural production, fertilization is essential, but if you do not understand the structure of soil nutrients in cultivated land, blind fertilization will not only cause problems such as weakening of stress resistance and yield loss, but will also unnecessarily increase the cost of fertilizer. Therefore, for large grain producers, the use of soil nutrient testers to accurately measure soil nutrients is an important part of controlling scientific fertilization, and is also an important prerequisite for avoiding huge losses.
