TL;DR: Future research on biophysical interactions should concentrate on exploiting the diversity that exists within and between species of trees, determining interactions between systems at different spatial and temporal scales, and improving understanding of belowground interactions.
Abstract: The rate and extent to which biophysical resources are captured and utilized by the components of an agroforestry system are determined by the nature and intensity of interactions between the components. The net effect of these interactions is often determined by the influence of the tree component on the other component(s) and/or on the overall system, and is expressed in terms of such quantifiable responses as soil fertility changes, microclimate modification, resource (water, nutrients, and light) availability and utilization, pest and disease incidence, and allelopathy. The paper reviews such manifestations of biophysical interactions in major simultaneous (e.g., hedgerow intercropping and trees on croplands) and sequential (e.g., planted tree fallows) agroforestry systems.

TL;DR: Trees can influence both the supply and availability of nutrients in the soil as discussed by the authors, and trees can increase the supply of nutrients within the rooting zone of crops through (1) input of N by biological N2 fixation, (2) retrieval of nutrients from below the root zones of crops and (3) reduction in nutrient losses from processes such as leaching and erosion.
Abstract: Trees can influence both the supply and availability of nutrients in the soil. Trees increase the supply of nutrients within the rooting zone of crops through (1) input of N by biological N2 fixation, (2) retrieval of nutrients from below the rooting zone of crops and (3) reduction in nutrient losses from processes such as leaching and erosion. Trees can increase the availability of nutrients through increased release of nutrients from soil organic matter (SOM) and recycled organic residues.

TL;DR: In this article, the percentage of nitrogen derived from nitrogen fixation (%Ndfa) and soil development as a function of tree size on seven Texas sites were examined. And the tree basal diameters ranged from 3·2 cm to 76·4 cm.

TL;DR: Benefits from the tree products are more valuable than losses in cereal yields, explaining why trees are maintained on the agricultural fields and could reduce crop yield losses but cannot be expected to increase tree- and crop production.
Abstract: Sorghum grain yields under the karite and the nere are reduced by an average of 50% and 70% respectively, in comparison with yields in the open field. Soil fertility, limiting primary production in the region, is at least as favorable under the tree canopies as in the open field. Reduced light intensity, to a minimum of 20% under the nere canopy, is probably largely responsible for low sorghum production under the tree canopies. Benefits from the tree products are more valuable than losses in cereal yields, explaining why trees are maintained on the agricultural fields.

TL;DR: Variation in harvesting patterns and their ecological impacts can be explained in large part by differences in water availability between the two regions.
