• Maize Response to Fertilizer Dosing at Three Sites in the Central Rift Valley of Ethiopia (2014, background): “There can be a spatial variability in soil nutrients even within farms, due to different soil management [9], and such variability affects nutrient use efficiency and crop productivity [10].”
• Precision of farmer-based fertility ratings and soil organic carbon for crop production on a Ferralsol (2015, background): “The contrary is true for soils with low concentrations (Ebanyat, 2009; Mtambanengwe and Mapfumo, 2005; Musinguzi et al., 2013; Zingore et al., 2007).”
• Micro-dosing as a pathway to Africa’s Green Revolution: evidence from broad-scale on-farm trials (2010, background): “Keywords Fertiliser Nitrogen Semi-Arid Smallholder Sorghum Maize Pearl Millet Southern Africa Zimbabwe”
• The State of Soil Degradation in Sub-Saharan Africa: Baselines, Trajectories, and Solutions (2015, background): “Their activities, such as farmer management practices, play a large role in soil degradation and may vary greatly between seasons and across years [13,14].”
• When yield gaps are poverty traps: The paradigm of ecological intensification in African smallholder agriculture (2013, background): “The amounts of manure necessary to restore productivity of degraded outfields on the granitic sandy soils of Zimbabwe were as much as 17 t ha−1 year−1, complemented with 100 kg ha−1 year−1 of N as mineral fertiliser (Zingore et al., 2007).”
• Analysing trade-offs in resource and labour allocation by smallholder farmers using inverse modelling techniques: A case-study from Kakamega district, western Kenya (2007, background): “Studies across Africa indicate that smallholder farmers invest proportionally more (cash, nutrient and labour) resources in the relatively fertile fields near the homestead, particularly on mixed crop-livestock farms (e.g. Samaké et al., 2005; Zingore et al., 2007; Tittonell et al., 2007).”
• Communicating complexity: Integrated assessment of trade-offs concerning soil fertility management within African farming systems to support innovation and development (2011, methodology): “…have been used to generate typologies in different study sites, using wealth classes identified by key informants and the farmers’ themselves (Zingore et al., 2007b; Figueroa et al., 2008), by qualitative analysis based on detailed field work with farmers including farmers’ production…”
