The presence of excess salt in the soil requires

Correct option is C

✅ (c) high water storage efficiency
· For salt-affected soils, irrigation should aim for high water storage efficiency to ensure water percolates uniformly and leaches down salts from the root zone.
· Efficient storage minimizes water wastage and enhances salt leaching.
· Essential for reclaiming saline soils.
❌ (a) high water application efficiency
· Though important, it does not directly address the need for salt leaching.
· Water storage in root zone is more critical.
❌ (b) low water use efficiency
· Low water use efficiency is undesirable in agriculture.
· Efficient water use is always preferred, even in salt-affected soils.
❌ (d) low water storage efficiency
· Low storage efficiency leads to poor salt leaching and is counterproductive in saline soils.
· Incorrect option.
