Can improve the utilization efficiency of chemical fertilizer. The slow-release fertilizers produced by Hubei Hongfu Sanhuan Chemical Co., Ltd. are basically coated with a film outside the fertilizer core, which makes the slow-release fertilizers have a slow-release effect, which can reduce the gas state and leaching loss of fertilizers, thus improving the utilization efficiency of fertilizers.
When using slow-release fertilizer, it can be mixed in the soil, buried in several small holes in the soil, or directly sprinkled on the soil surface, but try to avoid summer, otherwise it will be prone to fertilizer damage.
