impact of organic fertilizer on soil fertility
U

Research consistently shows that organic fertilizers significantly improve soil organic matter, microbial activity, and nutrient availability compared to synthetic alternatives, with long-term benefits for crop yield and soil health.

Several studies indicate that organic fertilizers improve soil fertility through enhanced nutrient cycling and microbial diversity [1] [2]. Some studies further demonstrate significant yield improvements in organic compared to chemical-only approaches [3].
