Mgr. Cannell et al., THE CENTRAL AGROFORESTRY HYPOTHESIS - THE TREES MUST ACQUIRE RESOURCES THAT THE CROP WOULD NOT OTHERWISE ACQUIRE, Agroforestry systems, 34(1), 1996, pp. 27-31
A simple tree-crop interaction equation is re-interpreted in terms of
resource capture. Benefits in physical yields from agroforestry are to
be expected only when there is complementarity of resource capture by
trees and crops. Most of the current biophysical hypotheses formulate
d for agroforestry research are based on this central tenet, specified
for various resources, soil and climatic conditions.
