Discuss different in situ moisture conservation practices recommended in dryland areas.
In situ moisture conservation ensures rainwater is retained within the field, improving crop performance in drylands.
Key practices include:
Contour farming: Ploughing along contours reduces runoff.
Ridge and furrow system: Concentrates water in furrows, aiding germination.
Tied ridges: Small cross-bunds store rainwater temporarily.
Compartmental bunding: Divides fields into small compartments to reduce runoff and enhance infiltration.
Mulching: Use of crop residues, straw, or plastic sheets reduces evaporation.
Conservation tillage: Minimum tillage maintains soil cover and reduces water loss.
Vegetative barriers: Grasses or hedges along slopes slow down runoff and promote infiltration.
These practices are cost-effective, environmentally friendly, and suitable for rainfed crops like sorghum, pearl millet, and pulses.
