摘要
Trunk circumferences and canopy diameters of Prosopis glandulosa, P. chilensis and P. alba, and soil nitrogen under and between the trees were measured in a seven-year-old plantation at the University of California, Riverside. P. glandulosa had the smallest biomass of the three species. However, the nitrogen concentration of the soil under P. glandulosa was higher than under the other two species. Presumably more nitrogen is cycled through the leaves of this species rather than invested in wood production, where it would be sequestered. The soil nitrogen accumulation under P. glandulosa was significantly higher (total and subsurface) than that measured in soil taken between trees. The soil nitrogen content under P. chilensis and P. alba was not significantly different than that between the trees. These results indicate that the choice of woody legume in an agroforestry system will depend on its intended use. The most efficient nutrient cycling is not necessarily associated with the best biomass production. © 1990 Kluwer Academic Publishers.
