Introduction

Cover crops are non-harvested plants grown primarily to protect and enhance soil health between main cropping seasons. They play a vital role in sustainable agriculture by reducing erosion, improving nutrient cycling, increasing organic matter, and enhancing soil structure. The interactions between cover crops and soil influence physical, chemical, and biological properties, creating a foundation for long-term productivity and ecosystem resilience. Understanding these interactions is essential for designing cropping systems that optimize soil fertility and support sustainable farming practices [1,2].

Discussion

Cover crops affect soil physical properties by reducing erosion, improving aggregate stability, and increasing porosity. Their root systems penetrate the soil, creating channels that enhance water infiltration, reduce compaction, and facilitate gas exchange. Deep-rooted species, such as radish or sunflower, break compacted layers and improve soil structure, while fibrous-rooted grasses stabilize the surface layer and protect against runoff. This physical improvement also aids in water retention and reduces the risk of drought stress for subsequent crops.

Chemical interactions are equally significant. Cover crops contribute to nutrient cycling by fixing atmospheric nitrogen, solubilizing phosphorus, and scavenging residual nutrients from previous crops. Leguminous cover crops, such as clover or vetch, establish symbiosis with nitrogen-fixing bacteria, enriching the soil with bioavailable nitrogen. Non-leguminous species capture excess nutrients, preventing leaching and maintaining fertility. The decomposition of cover crop residues adds organic matter, which enhances cation exchange capacity, buffers soil pH, and supports long-term nutrient availability [3,4].

Biologically, cover crops foster diverse microbial communities. Root exudates provide energy sources for soil microorganisms, promoting beneficial bacteria and fungi that enhance nutrient availability, suppress pathogens, and improve soil structure. Mycorrhizal associations are supported by perennial cover crops, increasing phosphorus uptake for future crops. Cover crop–soil interactions also stimulate enzyme activities that drive decomposition and nutrient cycling, further enhancing soil fertility [5].

Selecting appropriate cover crop species and management practices, such as timing of planting and termination, is crucial to maximize benefits. Mixtures of legumes and grasses often provide complementary functions, combining nitrogen fixation with soil stabilization and organic matter addition. Integrating cover crops into rotations enhances soil resilience, reduces dependency on chemical fertilizers, and promotes sustainable production systems.

Conclusion

Cover crop–soil interactions are fundamental to building healthy, productive, and resilient agricultural systems. By improving soil structure, enhancing nutrient cycling, and fostering beneficial microbial activity, cover crops strengthen soil health and support sustainable cropping practices. Strategic use of cover crops in rotations not only mitigates soil degradation but also increases long-term productivity, reduces environmental impact, and contributes to climate-smart agriculture. These interactions highlight the vital role of cover crops in sustainable and resilient agroecosystems.
