No-Till Farming
No-till farming involves growing crops without plowing the land, which preserves the soil structure, reduces erosion, and improves water absorption. The remaining crop residue on the field surface protects the soil from rain and wind.
Grassed Waterways
Grassed waterways are natural or constructed channels that are shaped or graded and planted with grass to form a pathway for surface water. They help to convey water off farmland without causing soil erosion by reducing the speed and volume of water flow.
Contour Plowing
Contour plowing is the practice of plowing along the contours of the land, rather than in straight rows. This helps to reduce runoff by creating natural dams that slow the flow of water down the slope, thereby preventing soil erosion.
Terracing
Terracing is the creation of flat areas on a slope to reduce water runoff and soil erosion. Terraced fields decrease the velocity of water flow and increase water infiltration into the soil.
Windbreaks
Windbreaks, such as trees and shrubs planted in rows, reduce wind velocity and protect soil from wind erosion. They also serve as barriers that help to trap soil particles that might otherwise be carried away by the wind.
Cover Crops
Cover crops are grown to cover the soil rather than for the purpose of being harvested. They help to prevent erosion by protecting the soil from rain and wind, improving soil structure, and enhancing water infiltration.
Strip Cropping
Strip cropping involves alternating strips of different crops or alternating strips of crop and fallow land. This interrupts the flow of water, reducing soil erosion and run off by creating more surface area for the water to permeate.
