Maximum production of paddy per unit water consumption can be best achieved in a
- (a) Non-porous soil
- (b) Porous soil
- (c) Impervious soil
- (d) Soil that allows slow percolation
Show the answer and explanation
Answer: (d) Soil that allows slow percolation
Soil with slow percolation keeps standing water with the least loss.
Why the others are wrong
(a) Completely non-porous soil can’t support roots and aeration.
(b) Porous soil drains too fast.
(c) Impervious soil waterlogs.
The trap
None.
🔒 Paddy needs slow-draining clay soils (puddling reduces percolation).
