The following problems arise when applying solid micro-fertilizers to the soil:
1.Soil compaction: Long-term application of a large amount of solid micro-fertilizer will lead to soil compaction, poor soil permeability, and affect the growth and development of crop roots.
2.Soil salinization: Excessive application of solid micro-fertilizer will cause the concentration of salt ions in the soil to be too high, leading to soil salinization and affecting the absorption of water and nutrients by crops.
3.Soil pH imbalance: solid micro-fertilizer contains a large amount of acidic substances, long-term application of a large amount of soil will acidify the soil, destroy the soil pH balance, and affect the growth of crops.
4.Soil microbial imbalance: solid micro-fertilizer contains a large amount of inorganic salts, which will inhibit the activity of soil microorganisms, destroy the balance of soil microorganisms, and affect the ecological balance of soil.
5.Crop malnutrition: The variety of nutrients in solid micro-fertilizer is limited, and long-term large-scale application will lead to crop malnutrition, affecting the growth and yield of crops.
Therefore, attention should be paid to the appropriate amount and reasonable combination when applying solid micro-fertilizer to avoid adverse effects on soil and crops caused by excessive application. At the same time, we should choose solid micro-fertilizer products with reliable quality and good brand reputation, and avoid using fake and shoddy products to cause greater harm to the soil and crops.
