Question

name the reason due to which the amount of salt increases in soil​

Answer 1

Answer:

Salts may accumulate on the soil surface because they cannot leach out of the root zone. Plants can also be damaged by salt effects or toxicity. In saline and saline-sodic soils, high concentrations of soluble salts reduce the amount of available water for plants to use.

Answer 2

The terms salt and salinity are often used interchangeably, and sometimes incorrectly. A salt is simply an inorganic mineral that can dissolve in water. Many people associate salt with sodium chloride— common table salt. In reality, the salts that affect both surface water and groundwater often are a combination of sodium, calcium, potassium, magnesium, chlorides, nitrates, sulfates, bicarbonates and carbonates (Table 1).

These salts often originate from the earth’s crust. They also can result from weathering, in which small amounts of rock and other deposits are dissolved over time and carried away by water. This
