One major limitation in tropical agriculture is the loss of productivity of soils due to continuous cultivation. This is often due to leaching losses of nutrients, erosion or crop removal. There is need to explore improving productivity of soils by u

The Proceedings of the International Plant Nutrition Colloquium XVI. UC Davis: Department of Plant Sciences, UC Davis. Retrieved from: http://www.escholarship.org/uc/item/7hr282j2
African soils have an inherently poor fertility because they are very old and lack volcanic rejuvenation. Inappropriate land use, poor management and lack of input have led to a decline in productivity, soil erosion, salinization and loss of vegetati

The Proceedings of the International Plant Nutrition Colloquium XVI. UC Davis: Department of Plant Sciences, UC Davis. Retrieved from: http://www.escholarship.org/uc/item/6b33q7rk
Urban and peri-urban agriculture (UPA) covers about 10% of the global food demand, and substantially contributes to the income of the urban poor. However, surprisingly little quantitative data exist about the sustainability and resource use efficienc
