Conservation Tillage

Agricultural practices that minimize the disruption of the soil's structure and composition, aiming to improve water absorption, reduce erosion, and enhance soil health, ultimately supporting sustainable agriculture.

Terracing

An agricultural practice of creating terraces on steep slopes to reduce soil erosion and water runoff, while making steep land more usable for farming.

Wind Erosion

The process of removing soil particles by wind, leading to land degradation and a loss of soil fertility.
