WHAT IS LEACHING?

Leaching is defined as the washing down or downward movement of soil nutrients beyond the reach of the roots of crop plant.

 

This is usually as a result of too much rainfall.
Leaching is more on sandy soil than any other type of soil. On the savannah parts of west Africa, Leaching is not so much due to low rate of rainfall, however the rate of rainfall is much more greater than the rate of evaporation.
This means that water remains in the soil for a longer period of time thereby causing fast chemical leaching.
