To evaluate the quality of soil, it is not easy to look at the soil nutrient content. It is also necessary to analyze the environmental indicators such as soil pH and soil EC, and combine them with different environmental parameters. The EC value of the soil indicates the total concentration of soluble salts in the matrix, reflecting on the one hand the various ionic nutrients in the soil or fertilizer, and on the other hand the content of other soluble minerals. The healthy growth of crops requires an appropriate EC value environment support, usually between 0.4 and 1, with a maximum of no more than 2.5. Using soil EC scientific guidance, soil salinity and crop growth can be more and more effective, eliminating soil EC too high or too low to hinder crop growth, and improve agricultural planting quality.
In recent years, due to unreasonable water and fertilizer management, soil acidification, secondary salinization, microbial inactivation, accumulation of pests and diseases have become more and more common, and unhealthy soils have not only seriously affected crop growth and high yield, but also restricted The high quality and efficient development of modern agriculture, therefore the development of modern agriculture, also needs to improve the safety and quality of the soil. In this context, the demand for soil testing and treatment has proliferated, and the application of soil testing instruments such as soil EC meters has become more and more extensive, playing an important role in soil problem management and production guidance.
The soil EC meter is used to test the soil for salt. According to the growth needs of different crops and the growth needs of different periods, the soil improvement, fertilization and irrigation can be carried out reasonably, and the soil can be adjusted to the crop environment to meet most crop pairs. The requirement of EC value makes soil salt and crop growth more and more correct. These important tasks not only can significantly improve soil function, but also can greatly improve the utilization rate of water and fertilizer, improve crop growth, and provide important support for the development of healthy and green high-quality and high-yield agriculture.
