6 CAUSES OF SOIL DEGENERATION

6 CAUSES OF SOIL DEGENERATION

The following are the causes of soil degeneration Poor agricultural practices such as burning of land and over cultivation or monoculture cause soil to be deficient in some mineral nutrient leading to loss of soil fertility other human activities such as quarrying and construction of roads interfere with soil structure leading to sail degeneration soil …

MEANING OF CHELUVIATION IN SOIL FORMING PROCESS

MEANING OF CHELUVIATION IN SOIL FORMING PROCESS

Cheluviation is the process in which the minerals are dissolved and transported downwards under the influence of chelating agents. Chelating agents are the organic acids produced after the decomposition of organic matter Cheluviation is one of the processes of soil formation.  The echolocation process is similar to leaching in that it involves the downward movement …

WHAT IS LEACHING?

WHAT IS LEACHING?

Leaching is the removal of materials in solution or suspension downwards as water moves vertically through the soil body by the force of gravity. Leaching results in movements of soluble and suspended materials in water percolation. Leaching involves two forms: Elluviation – which is washing out of materials in solution or suspension from the overlying …
