Field data have suggested that under P-deficient conditions, legumes supplied with phosphate rock (PR) increase P acquisition by a subsequent maize crop compared to direct application of PR to maize. This study assessed the mechanism of this positive rotational effect in terms of soil P availabil...

Traditionally, crop production in sub-Saharan Africa (SSA) depends primarily on mining soil nutrients. Integrated Soil Fertility Management (ISFM) is an approach for intensifying agriculture in SSA that aims at maximizing the agronomic efficiency (AE) of applied nutrient inputs. ISFM contains the...

Agronomic use efficiency of N fertilizer in maize-based systems in sub-Saharan Africa within the context of integrated soil fertility management
There are several indications that legumes are capable of accessing sparingly soluble phosphorus (P) in the soil through root-induced processes. We hypothesize that this plant-induced mobilization of P can be demonstrated if the plant accessible P assessed by isotopic dilution ( L-value ) exceeds...

Soil fertility problems resulting in low maize yields in smallholder farms are common in the West
African moist savanna. The effectiveness of commercial foliar fertilizers in improving maize
growth and yield was evaluated in three savanna agro-ecological zones of Nigeria in two steps.
In step one...

Soil fertility gradients develop on smallholder farms due to preferential allocation of inputs. A multi-location on-farm trial was
conducted in Meru South, Central Kenya whose overall aim was to test minimum tillage and crop-residue retention practices in
socio-ecological niches across heteroge...

Soil fertility decline is a major constraint to bean (Phaseolus vulgaris L.) and maize (Zea mays) production in the Central Highlands of Burundi. Nutrient sources, specifically fertilizers, are paramount to increasing the production in the regions. Hence, improving fertilizer use efficiency is co...
