Summary
This 2024 field study, conducted across sub-Saharan African agroecosystems, investigates the agronomic and economic performance of localized (point-source or targeted) application of manure and inorganic fertilizers to cereal crops, as compared to broadcast methods or conventional practice. The authors report improvements in productivity, nutrient use efficiency, and farm profitability, suggesting that precision placement of inputs—rather than blanket application—offers a cost-effective pathway to intensification in resource-constrained smallholder systems. The findings align with growing interest in 'precision agriculture' adapted to smallholder contexts in the region.
UK applicability
UK cereal systems are typically large-scale and mechanised, with relatively high nutrient availability and different climatic constraints; direct application of these localized manure and fertilizer placement findings to intensive arable production would require adaptation. However, principles of improving nutrient use efficiency and reducing input waste may inform sustainable intensification debates, particularly in organic or low-input systems.
Key measures
Cereal grain yield; nutrient use efficiency; resource use efficiency; profitability (net returns or benefit-cost ratios); possibly nutrient recovery rates
Outcomes reported
The study examined how localized (targeted) application of manure and fertilizers affects cereal crop productivity, nutrient use efficiency, and farm profitability across sub-Saharan African contexts. Measurements likely included grain yield, nutrient recovery, input cost-benefit ratios, and economic returns.
