Tropical agriculture usually deals with severe limitations on management alternatives, arising from a combination of factors such as low-resource farmers, fragile lands, high pest susceptibility, etc. Under these conditions, agroecosystem properties other than productivity, such as stability, sus...
This chapter assessed the influence of socioeconomic factors, plot characteristics, food security, and climatic variables on the adoption of Climate-Smart Agriculture (CSA) technologies in southern Tanzania. Using data collected from 357 households and 464 agricultural plots, a multivariate probi...
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...
