Description We investigate the effects of smallholder farmer resource-endowment and soil nutrient management strategies
on plant nutrient uptake and growth across soil fertility gradients under semi-arid conditions. Soil fertility gradients
as influenced by farmers’ resource availability may affect the response of crops to fertilizer addition and
therefore productivity. The study was conducted in Njelele and Nemangwe smallholder areas (450-800 mm per
annum, unimodal) in north-western Zimbabwe. Soil and maize cobleaf samples were collected from fields of
farmers (varying resource endowment) located near to (homefields) and far away (outfields) from the farmers’
homesteads during the 2005-6 season. The samples were analysed for selected soil fertility indicators and soil
samples were further used to test maize growth response to various nutrient applications under greenhouse
conditions. Soil fertility (organic C, total N and available P) significantly (P
