Problems solved by technology

[0003] However, the fertilizers currently used on the market, due to the addition of too many inappropriate substances during the production process, cause soil compaction, poor ventilation hole capacity, and unbalanced nutrients during the fertilization process. Effectively promote the increase of crop production, and the heavy metal ions contained in the fertilizer will cause secondary pollution to the soil, and there are shortcomings such as low fertilizer utilization rate, which is inconvenient for people to use for a long time
