Soil nutrient analyzer to achieve the combination of land and land
Raw material is hot-rolled round steel, which is forged by air hammer and heat-treated to become a high-quality Grinding Ball. The Forged Steel Ball has high volume hardness, compact structure, fine grain and good wear resistance. Due to the stable quality of the raw materials, the impact toughness is as high as 12-15 J/cm2, and the breaking rate is less than 1%. Especially the large-diameter Steel Ball has the advantage that the cast steel ball cannot be achieved in the SAG mill.

In terms of fertilization, it is generally advocated in modern times that it is soil testing and formula fertilization, that is, firstly, soil nutrients are measured by a soil nutrient meter, and the ratio is formulated according to soil conditions and crop demand, and fertilization operations are performed. It can increase the utilization rate of chemical fertilizers, and at the same time avoid the contamination of soil with excessive fertilization, so that the crop-soil-fertilizer forms a benign cycle of matter and energy.
It must be understood that if the soil fertility is destroyed or consumed, it means that the ability to reproduce is reduced, and the quality and yield of agricultural cultivation are difficult to increase. Therefore, the development of modern agriculture must adhere to the combination of land use and land conservation, investment and production. In order to balance crops, to achieve the best results in crop fertilization, we also need to rely on professional soil testing instruments such as soil nutrient analyzers, and emphasize the interaction of nitrogen, phosphorus, and potassium fertilizers, and supplement the necessary micro- and micro-scales. The elements can achieve the goal of high and stable yield under the high intensity utilization of soil. At the same time, they must also adhere to various forms of organic fertilizer input, increase soil organic matter content, improve the ability of soil to retain water and fertility, and realize the healthy development of agricultural soil. .
At present, the country has also introduced the "Tokuji", which means that the importance of agricultural soil health is getting higher and higher. Realizing the combination of land use and land conservation has become a common goal for all humans. Therefore, it is precisely based on soil nutrient analyzers. The soil testing and formula fertilization will play an important role in the healthy cultivation of agricultural soil, and provide important technical force for further improving agricultural soil quality and agricultural production efficiency.
