Question

Increase in concentration of soluble salts in the soil is called ______.

Answer 1

Increase in concentration of soluble salts in the soil is called salination.

Explanation:

Salination occurs when soluble salts such as sodium, calcium, and magnesium ions accumulate in the soil, which adversely affects soil productivity and land quality. This process is common in semi-arid regions and can be accelerated by factors such as inadequate leaching, fluctuating groundwater levels, rapid surface evaporation, seawater intrusion in coastal areas, and irrigation with saline water without proper drainage. Salination renders soil less fertile and can make it unfit for most crops.
