Book Description
Two greenhouse studies were undertaken to evaluate: 1) the effects of rock phosphate additions and VA mycorrhizas on growth and nodulation of Inga edulis, Erythrina sp., and Centrosema macrocarpum, and 2) shoot pruning effects on rood dynamics, VA mycorrhizal infections and P and N accumulation in inga and centrosema on an Ultisol. Non-mycorrhizal plants required additon to between 30kg P/ha to 40kg P/ha to attain the same shoot weight as mycorrhizal plants without added P. Plants with mycorrhizae and rhizobia had significantly more nodules than plants with rhizobia alone. Shoot pruning reduced fine root biomass. The greater the intensity of shoot pruning the greater the decline in root biomass, VA mycorrhizal infection, and nodule activity. On acid soils with low P avalilability, additions of 20kg P/ha coupled with plant management to encourage vesicular arbuscular (VA) mycorrhizae could significantly improve the productivity of leguminous tree and pasture species. Two field experiments were performed on an Ultisol (pH 4.3 -4.4) to: 1) evaluate competition between inga hedgerows and crops in alley cropping; and 2) identify provenances of Gliricidia sepium with potential for alley cropping on acid soil. Root competition between inga hedgerows and crops became significant at eleven months after hedgerow establishment and resulted in lower grain yields from alley plots relative to non-alley controls. Fertilizer application and root pruning of hedgerows significantly improved yields across the shole alley. Root competition between hedgerows and crops, and asynchrony of nutrient release from inga prunings and nutrient demand by crops were porbably the main causes for low crop yields. Gliricidia provenance OFI 14/84 showed good tolerance to acid soil conditions and produced 60% more total biomass than the second ranked provenance. Selection of 14/84 for hedgerows in alley cropping, however, will result in excessive competition with crops. The use of less vigorous provenances may improve crop yields in alley cropping.

Book Description
Agroforestry in Sustainable Agricultural Systems examines the environmental and social conditions that affect the roles and performance of trees in field- and forest-based agricultural production systems. Various types of ecological settings for agroforestry are analyzed within temperate and tropical regions. The roles of soil, water, light, nutrient and pest management in mixed, annual, woody perennial and livestock systems are discussed. Important new case studies from around the world offer innovative strategies that have been used successfully in raising forests and tree products on a sustainable basis for commercial harvesting and for providing other environmental services in land conservation and watershed management.

Faced with the growing problems of climate change, ecosystem degradation, declining agricultural productivity, and uncertain food security, modern agricultural scientists look for potential relief in an ancient practice. Agroforestry, if properly designed, can mitigate greenhouse effects, maintain ecosystem health and biodiversity, provide food sec
