Consider the following statements regarding the Salinization.

1. Irrigation of land helps in reduction of salinity of soil.
2. It occurs on soil due to improper agricultural practices only.
Select the correct statement using the codes given below.
a) 1 only
b) 2 only
c) Both 1 and 2
d) None of the above

Ans- d
Explanation-Salinization is the accumulation of the salts in the soil due to natural reasons or inefficient management practices like over-irrigation of farm land, inefficient water use, poor drainage, allowing water to pond for long periods and allowing seepage from irrigation channels, drains and water storages etc. These salts are detrimental for the crops as water intake is seriously affected.
Irrigation worsens the salinity problem of the soil. In fact, it is the prime cause of it. Statement 1 is thus wrong.
Statement 2 is also wrong as natural reasons are also behind salinization problem. You can read it here
