The concept of biophysical control plots becomes then less essential. A relevant modelling approach of interactions between trees and crops should 1) perform correctly for any tree/crop proportion and eve

This compensating effect was observed during a rather rainy year. The overall impact of leguminous intercrops on tree growth

The results demonstrate that direct placement of .N can be used to identify N sourcing

The simulations showed that the daily mean transmitted radiation was reduced from 92% of incident radiation under five-year-old trees to 37% under 20-year-old trees. The variability of transmitted radiation increased with tree growth. The row orientation had only small

Reasonable agreement between simulated and measured soil water content and dry matter production was obtained under the conditions in Niger. Global radiati
