Erythrina berteroana, E. fusca, E. poeppigiana, Gliricidia sepium, Leucaena leucocephala, and Senna siamea were grown for 15 months at two lowland sites in Colombia, L. leucocephala performed poorly in contrast to G. Sepium and S. Siamea.
The tree component of agroforestry systems may interfere with N cycling in several ways. In alley cropping systems, first of all, the prunings added during the different activities have a certain biochemical quality and subsequent N release characteristics. Secondly, the quality of the complete o...
In southern Africa, soil nutrient reserves are being depleted because of continued nutrient mining without adequate replenishment. The consequent downward spiral of soil fertility has led to a corresponding decline in crop yields, food insecurity, food aid and environmental degradation. The centr...
Root turnover may contribute a significant proportion of recycled nutrients in agroforestry systems and competition between trees and crops for nutrients and water may depend on temporal fine root regrowth patterns. Fine root biomass (? 2 mm) and fine root productivity were measured during one ye...
This paper explores the claim whether agro-forestry is a second soil fertility paradigm. The answer to this question, however, is not unequivocal. Farmers in Western Kenya generally do not apply fertiliser and rather rely on many soil fertility replenishment (SFR) strategies. Scientists recognise...
In the highland ecosystems where actions by some individuals or groups often generate off-site effects among a wide range of social actors and stakeholders, the use and management of natural resources are susceptible to multiple forms of conflicts. This paper examines the hypothesis that conflict...
This study evaluated the performance of tree legumes and other soil fertility management innovations used by farmers. The objectives of the study were to: examine the extent that farm attributes, typology of farmers and field management practices have affected the adaptation and use of agroforest...
