To improve soil health naturally, I would recommend: 1) Adding organic manure or compost: This enriches the soil with humus, improves its water-holding capacity, and provides a slow release of nutrients, fostering beneficial microbial activity. 2) Practicing crop rotation with legumes: This helps replenish nitrogen in the soil naturally, reducing the need for synthetic nitrogen fertilizers, and breaks pest/disease cycles. 3) Minimizing tillage (no-till farming): This helps preserve soil structure, reduces erosion, conserves moisture, and protects the soil's microbial community. These practices promote long-term soil fertility and ecosystem health.
