Description
Soil fertility decline is a major constraint to crop productivity on smallholder farms in Africa. The objective of this study was to evaluate the long-term (up to nine years) impacts of nutrient management strategies and their local feasibility on crop productivity, soil fertility status and rainfall infiltration on two contrasting soil types and different prior management regimes in Murehwa, Zimbabwe. The nutrient management strategies employed in the study were: a control with no fertiliser, amendments of 100kg Nha−1, 100kg N+lime, three rates of manure application (5, 15 and 25tha−1) in combination with 100kg Nha−1, and three rates of P fertiliser (10, 30 and 50kg Pha−1) in combination with 100kg N, 20kg Ca, 5kg Zn and 10kg Mnha−1. Maize grain yields in sandy soils did not respond to the sole application of 100kg Nha−1; manure application had immediate and incremental benefits on crop yields on the sandy soils. A …
