Leaching Definition- The reclamation of saline soil is done by the process of Leaching. In this process the land is flooded with an adequate quantity of water. The salts present in the soil get dissolved in this water which percolates down to join the water table or is drained away by surface or subsurface drainage systems. This process of soil reclamation is called leaching.
What is the Sodium Absorption Ratio formula?
\(SAR= \frac{[Na]^{+}}{\sqrt{\frac{[Ca]^{2+}+[Mg]^{2+}}{2}}}\)
What is the leaching requirement?
Leaching Requirement- It is defined as the percentage of total irrigation water supplied that is drained away in leaching.
What is water logging?
An area is said to be waterlogged if the productivity of the land gets reduced due to the high water table. Water logging makes the soil ill aerated. It is a situation in which the soil is completely submerged in water and the plants in that area are not able to deploy the oxygen for carrying out the metabolic processes. Thus after prolonged water logging, the plants may die due to less availability of oxygen.
What is efflorescence?
The phenomenon of salts forming a thin crust on the surface after the evaporation of water from the surface is called efflorescence.
