A farming experiment in Malawi has demonstrated how simple changes in agricultural practices can significantly boost maize yields and improve soil health. The experiment, conducted by the International Maize and Wheat Improvement Center (CIMMYT), involved introducing conservation agriculture techniques to smallholder farmers in the country.

The techniques included using mulch, minimal soil disturbance, and crop rotation. These changes helped improve soil fertility, water retention, and weed control, resulting in increased maize yields of up to 50%.

The experiment also found that the conservation agriculture techniques helped reduce soil erosion and improve soil moisture, leading to increased resilience against drought. The findings highlight the potential of conservation agriculture to transform smallholder farming systems in Malawi and other countries facing similar challenges.
