OBJECTIVE FORESTRY

Detailed explanation-1: -The excessive use of water for irrigation in dry climates, with heavy soils, causes salt accumulation because they are not washed out by rainfall. The process occurs in cultivated areas where irrigation is associated with high evaporation rates and a clay texture of the soil.

Detailed explanation-2: -Which type of irrigation causes soil salinization? Flood irrigation causes soil salinization at higher rates than other types of irrigation.

Detailed explanation-3: -Excessive irrigation leads to soil salinity as it causes water logging. The evaporation of excess water concentrates salt at the soil surface. This causes an increase in the soil salinity. The crops die as the roots of the crop plants have limited access to oxygen and increased salinity.
