Multiple soil and landscape properties are associated with the spatial variation of selenium concentration in maize grain in Malawi Open
Dietary selenium (Se) deficiency is widespread in Malawi, due to the limited supply of Se in the predominantly maize-based food system characterised by low Se concentration. This study examined the spatial variation of Se in maize grains i…

Organic carbon to clay ratios can help to optimize organic amendment use at the farm level Open
Realistic targets for soil organic carbon (SOC) concentrations are needed, accounting for differences between soils and land uses, to help farmers manage the SOC across their farms. We assess the use of SOC/clay ratio for this purpose usin…
