The Upper Oueme catchment in the West African subhumid zone is a region in Northern Benin, which actually experiences major changes in land use, water availability, and population density. In the context of the IMPETUS project, the present work aimed to i) identify nutrients which are limiting productivity on the basis of soil and plant analysis, ii) compare effects of fertilizer application nutrition to current farmer’s practice, iii) determine the water consumption per unit of biomass (maize) and per unit of area, and iv) assess (simplified) nutrient balances to predict longterm trends of nutrient availability and soil productivity. Field experiments were carried out in 2001 and 2002 using a randomized complete block design with four trea...
