Soil salinity refers to the excess salt accumulation in soil, affecting plant growth and water absorption.
Soil salinity arises from dry climates, low precipitation, high evaporation rates, poor drainage, improper irrigation and fertilizer misuse.
Soil salinity impacts ecology and human life by causing soil degradation, crop production, flood risk, and decreasing terrestrial biodiversity.
To reduce soil salinity, increase drainage, grow salt-tolerant crops, remove salt crystals, restore soil balance, reduce evaporation, and use fertilizers.
