Question
Chapter 38.2, Problem 1CC
Summary Introduction
To explain: The problems associated with nutrient leaching with respect to sandy and clay soil.
Introduction: Leaching is the process by inorganic ions, minerals and nutrients are removed from different kinds of soil due to percolation of water through the materials. The fertility of the soils can be reduced to heavy rainfall because of the leaching of a large number of nutrients from the soil. These nutrients enhance the growth of aquatic plants and algae.
