Residual soil-applied zinc improves grain zinc nutritional quality of maize grown under contrasting soil types in Malawi Open
Introduction A proper understanding of the residual value of zinc (Zn) is essential for sustainable biofortification of food crops. This study hypothesized that Zn applied at rates higher than the current national recommendation would have…

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…

In vitro determination of the protein quality of maize varieties cultivated in Malawi using the INFOGEST digestion method Open
There is an urgent need to alleviate protein deficiencies in low-income countries where cereal-based diets dominate. The objective of this study was to use the INFOGEST static digestion method and a recently established analytical workflow…

Assessing the residual benefit of soil-applied zinc on grain zinc nutritional quality of maize grown under contrasting soil types in Malawi. Open
A proper understanding of the residual value of zinc (Zn) is necessary for sustainable biofortification of food crops. This study aimed to establish the extent to which application of Zn at the national rate, plus two experimentally elevat…

Agronomic biofortification increases grain zinc concentration of maize grown under contrasting soil types in Malawi Open
Zinc (Zn) deficiency remains a public health problem in Malawi, especially among poor and marginalized rural populations, linked with low dietary intake of Zn due to consumption of staple foods that are low in Zn content. The concentration…

Cereal grain mineral micronutrient and soil chemistry data from GeoNutrition surveys in Ethiopia and Malawi Open
The dataset comprises primary data for the concentration of 29 mineral micronutrients in cereal grains and up to 84 soil chemistry properties from GeoNutrition project surveys in Ethiopia and Malawi. The work provided insights on geospatia…

Cereal grain mineral micronutrient and soil chemistry data from GeoNutrition surveys in Ethiopia and Malawi Open
Through the GeoNutrition project, 1352 georeferenced staple cereal grain and soil sample pairs from Ethiopia’s Amhara, Oromia, and Tigray regions and 1812 sample pairs from Malawi were collected from farms under a rainfed and smallholder f…

Increasing zinc concentration in maize grown under contrasting soil types in Malawi through agronomic biofortification: Trial protocol for a field experiment to detect small effect sizes Open
The prevalence of micronutrient deficiencies including zinc (Zn) is widespread in Malawi, especially among poor and marginalized rural populations. This is due to low concentrations of Zn in most staple cereal crops and limited consumption…

Sorbent-embedded sheets for safe drinking water in developing countries: a case study of lead(II) removal by a zeolite-embedded sheet Open
Although many kinds of materials for water purification are known, easy-to-use methods that ensure the safety of drinking water for rural populations are not sufficiently available. Sorbent-embedded sheets provide methods for the easy remo…
