Answers
Answer:
(i) Contour farming: Contour farming may be defined as ploughing, seeding, cultivating and harvesting across the slope, rather than with it. (ii) Strip cropping: On land with a dissected slope, planting crops on contour strips will be an effective erosion deterrent.
Soil Erosion Simple Definition
Soil erosion is a gradual process of movement and transport of the upper layer of soil (topsoil) by different agents – particularly water, wind, and mass movement – causing its deterioration in the long term.
In other words, soil erosion is the removal of the most fertile top layer of soil through water, wind and tillage.
cause
1) Sheet erosion by water;
2) Wind erosion;
3) Rill erosion – happens with heavy rains and usually creates smalls rills over hillsides;
4) Gully erosion – when water runoff removes soil along drainage lines
5) Ephemeral erosion that occurs in natural depressions.
