- •
Simulations of crop-dependent water balances at four slope positions.
- •
Leaf area index of lucerne as proxy for root and crop development.
- •
No effects for Luvisols at plateau and flat mid slope position.
- •
Capillary rise of water in colluvial soil of hollows by hillslope hydrology effects.
- •
Less crop growth at steep slope increased percolation and leaching.
