To address soil caking, organic fertilizer equipment manufacturers can offer the following recommendations:

1. Increase the application of organic fertilizer: Organic fertilizer is rich in organic matter, which can increase soil aeration and water permeability, reducing soil compaction. Increasing the application of organic fertilizer, bio-organic fertilizer, and in-situ incorporation of vegetable straw into the field can improve soil aggregate structure and enhance its fertilizer and water retention capacity. The microbial communities in organic fertilizers promote the growth and reproduction of soil microorganisms, increase the content of active organic matter in the soil, improve the soil microbial community structure, enhance soil microbial metabolic activity, and promote soil nutrient cycling.

2. Appropriate fertilization: Apply fertilizer appropriately based on soil fertility and crop needs, avoiding excessive use of chemical fertilizers to reduce soil pH imbalance and damage to aggregate structure.

3. Deep tillage: Combine deep tillage and rotary tillage. A reasonable and appropriate deep tillage depth of approximately 35 cm is beneficial for protecting the soil's topsoil structure and promoting crop root growth. 4. Use soil conditioners: Divalent cations such as silicon, calcium, and iron in these conditioners combine with organic and inorganic colloids in the soil to quickly form soil aggregates, addressing soil compaction and promoting crop root growth.

5. Optimize organic fertilizer production lines: To address the problem of organic fertilizer clumping, a double-roller differential-speed fertilizer clump crushing and fertilization device can be used. By optimizing the fertilization device's performance, the quality and efficiency of fertilization can be improved.

These measures can effectively address soil caking, increase soil fertility and crop yields, and promote sustainable agricultural development.
