Soil erosion can be controlled by adopting land management practices and also by changing the pattern of some human activities which accelerate soil erosion.
(i) Contour farming: Contour farming may be defined as ploughing, seeding, cultivating and harvesting across the slope, rather than with it.
Thomas Jefferson, who wrote in 1813, “we now plough horizontally, following the curvature of the hills …. Every furrow thus acts as a reservoir to … retain waters … scarcely an ounce of soil is now carried off.”
(ii) Strip cropping:
On land with a dissected slope, planting crops on contour strips will be an effective erosion deterrent. For effective control the width of the contour strip should vary inversely with the length of the slope. Strip cropping should be combined with crop rotation, so that a strip planted to a soil depleting, erosion-facilitating corn crop one year will be sown to a soil-enriching and protecting strip of legumes the next year.
