How does no-till farming primarily affect soil health?

No-till farming positively impacts soil health by helping to retain soil moisture and nutrients. This method involves leaving the soil undisturbed from previous seasons, which preserves the natural structure and biological activity of the soil. As a result, it enhances water infiltration and decreases evaporation rates, making moisture more readily available to crops.

Furthermore, no-till practices reduce erosion—both wind and water—which often contributes to the loss of nutrients and the degradation of soil quality. The presence of crop residues on the soil surface protects against erosion and helps to improve soil organic matter over time, forming a healthier soil ecosystem. This healthy ecosystem supports a diverse population of soil organisms that contribute to nutrient cycling and overall soil fertility.
