Why should farmers enhance the amount of humus in their farmlands?

Farmers should enhance the amount of humus in their farmlands because it improves soil fertility by increasing nutrient retention and water-holding capacity, leading to better crop yields. Humus also promotes beneficial microbial activity, which is essential for healthy soil ecosystems. Additionally, it helps prevent soil erosion and enhances resilience against extreme weather conditions, contributing to sustainable farming practices. Overall, increasing humus levels supports long-term agricultural productivity and environmental health.
