- Contour farming: Cultivation and planting done across the slope helps in
holding water thereby increasing infiltration and reducing runoff.

- Mulching: covers the soil thereby reducing splash erosion/reduces speed of
runoff.

- Strip cropping alternating strips of crops that give good soil cover with those
that give little soil cover controls movement of soil particles thereby helping in
control of erosion.

- Vegetated waterways: vegetation in waterways slows down run off/traps
eroded soil particles Hereby preventing further erosion.

- Afforestation/reafforestation trees, protect soil from splash erosion by
atomising - raindrops/encourage water infiltration/protect soil from winds,
which could detach and remove soil particles,

- Inter-cropping crops which do not cover soil with crops that have good ground
cover.

- Minimum tillage so as to maintain good soil structure/have a seed bed with
rough surface such that .soil particles are not easily detached encourage
water percolation

- Cover cropping: establishing a crop that spreads over the surface of soil
thereby protecting soil from effects of raindrops.

- Grass strips filter strips are left between cultivated/cropped strips of land to
reduced
