Discuss how specific land-use management strategies, such as no-till agriculture, can result in conservation and restoration of soils and financial savings
What will be an ideal response?
Conventional industrial agriculture includes plowing fields after each harvest to aerate the soil and work crop residues into the soil to nourish it. However, tilling leaves the surface exposed and can increase both wind and water erosion. By using no-till agriculture, only a thin strip is cut in the soil, enough to allow planting seeds but otherwise leaving rooted vegetation untouched. Using this method, yields are often equal to or better than in conventional tillage, water retention of soils increases, and erosion is reduced. In addition, less time, energy, and mechanical resources are needed in cultivation, resulting in financial savings, not to mention the savings on fertilizer from reduced erosion.
