Problems solved by technology

There are too many types of fertilizers provided by this patent, which will affect the soil quality, and its trace elements exist in the form of sulfate, which has the problem of difficulty in absorption
Long-term single application or unreasonable application of chemical fertilizers will easily lead to a decrease in soil organic matter content, a decrease in soil pH, a decrease in fertilizer use efficiency, changes in the structure of soil microbial populations, degradation of soil quality, and damage to the ecological balance of farmland
