          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. As we know that the topsoil contains all the nutrients and

          humus which help in the production of good crops and if all the nutrients are carried away
          then it will be a great loss of mankind.
