Answer: Drip irrigation
Soil erosion is a natural phenomena in which surface and subsurface layers of soil is removed, displaced to other location under the influence of agents like water and wind. This processes limits the fertility of soil considerably.
Drip irrigation is the method of irrigation of agricultural field. This method transfers water directly into the root zone of plants present in the subsurface and deep soil layers by using valves, pipes and tubes, hence prevents the surface water runoff, as top soil irrigation can remove and displace the fertile layer. Therefore, this method prevents soil erosion.
