  • Strip cropping – alternating strips of crops that give good soil cover with those that give little soil cover controls movement of soil particles hence control soil erosion.
  • Vegetated water ways – this slows down run off/trap eroded soil particles thereby preventing soil erosion.
  • Afforestation/re-afforestation – trees protect soil from splash erosion by atomizing rain drop/encourage water infiltration/protect soil from wind which could detach and remove soil particles.
  • Intercropping – crops which do not cover soil and crops that have good ground cover should be planted together to prevent splash erosion/surface run off.
  • Minimum tillage –this maintains good soil structure.
  • Cover cropping – this spread over the surface of soil hence protect soil from effects of raindrops.
  • Crop rotation – maintains soil cover for protection against soil erosion/improved soil structure.
  • Correct spacing – this ensures adequate soil cover.
  • Grass strips/filter strips – they are left between cultivated/cropped strips of land to reduce speed of water and filter out trodden soil.
  • Agroforestry – this intercepts raindrops/stabilizes soil acts as wind breaks.
  • Rotational grazing – this allows grass to recover thus prevent soil erosion.

1 x 8 = 8mks
