Anthropogenic soils of the Amazon Basin (Terra Preta, Terra Mulata) reveal that pre-Colombian peoples made lasting improvements in the agricultural potential of nutrient-poor soils. Some have argued that applying similar techniques could improve agriculture over much of the humid tropics, enhanci...

The soil fertility improvement potential of five tree legumes as alley hedges was studied on a Ultic Haplustox soil at a semi-arid highland site in Rwanda from 1983 to 1989. Tree species tested were C. calothyrsus Meissn., C. spectabilis DC, L. diversifolia (Lam.) de Wit., L. leucocephala (Lam.) ...

Effect of tree legumes in hedgerows on soil fertility changes and crop performance in the semiarid highlands of Rwanda
Alley farming involves the cultivation of food crops among hedgerows of multipurpose trees. Use of woody legumes provides N-rich mulch and green manure to maintain soil fertility and enhance crop production, and protein-rich fodder for livestock. The success of alley farming depends on a number o...
Changes in earthworm activity, water runoff, soil erosion, soil physical properties and fertility, and crop growth and yield caused by intercropping either maize (Zea mays L.) and cassava (Manihot esculenta Crantz) (MC) or maize, cassava and 'egusi' melon (Citrullus lanatus Thunb.) (MCM) on no-ti...

Zambia has three primary agro-ecological regions, with each region having specific ecological characteristics. Region II agro-ecological zone of Zambia has low nutrient reserves and poor water holding capacity due to moderately leached clayey to loamy soil; this has led to low soybean productivit...

Load estimates are more informative than constituent concentrations alone, as they allow quantification of on- and off-site impacts of environmental processes concerning pollutants, nutrients and sediment, such as soil fertility loss, reservoir sedimentation and irrigation channel siltation.

Soybean is becoming an important cash crop in northern Ghana. Yet the yields are low due to use of low yielding varieties and limited use of inputs. Greenhouse and field experiments were carried out to evaluate the effects of two phosphorus (P) sources and Rhizobium inoculation on growth, nodulat...

Agroforestry systems involving leaf removal for animal fodder may result in rapid depletion of soil fertility. The purpose of this research was to determine if the effects of leaf removal on soil fertility parameters and maize yield in aLeucaena leucocephalaalley cropping system could be reversed...
