Temporal changes in soil chemical and nutritional properties were evaluated in a long-term experiment conducted on Alfisols in West Africa. Effects of land use and cropping duration on soil chemical properties at 0-5 cm and 5-10 cm depths were evaluated for five treatments: (1) alley cropping with L

โฆ Synopsis
Hydrological and water-quality measurements were made on a 44 . 3 ha watershed under forest cover and following deforestation and conversion to an agricultural land-use. Under secondary tropical rainforest, water yield ranged from 2 . 2 per cent to 3 . 1 per cent of annual rainfall. Deforestation of 7 per cent of the watershed area increased water yield to 7 . 0 per cent of annual rainfall. Baseยฏow increased with deforestation, and increased progressively with time after deforestation. It was 5 .
