Question

difference between water loging and leaching

Answer 1

Waterlogging is a form of natural flooding when underground water rises to surface level as the result of over-irrigation.   Waterlogging can displace the spoil, affect the natural processes in the soil, and result in a build-up of toxic substances in the soil, which can impede plant growth in the immediate area.

leaching is the loss or extraction of certain materials from a carrier into a liquid (usually, but not always a solvent).
