Summary
This dataset paper presents primary data from the GeoNutrition project on mineral micronutrient concentrations in cereal grains and associated soil chemistry properties from Ethiopia and Malawi. The work supports investigation of linkages between agricultural and nutritional outcomes through comprehensive characterisation of geospatial variation in crop micronutrient composition and influencing soil factors. Data are published according to FAIR principles to enable secondary analysis of agriculture-nutrition relationships.
UK applicability
The findings are not directly applicable to UK conditions, as the study focuses on staple cereal production systems and micronutrient status in East African contexts with distinct soil types, climates, and cropping systems. However, the methodology and soil-crop nutrient linkage framework may be relevant for UK research on micronutrient profiling in cereals and understanding soil-mediated influences on crop composition.
Key measures
29 mineral micronutrient concentrations in cereal grains (measured by ICP-MS); 84 soil chemistry properties including soil pH, total nitrogen, total and organic carbon, cation exchange capacity, exchangeable cations, sequential extraction for sulfur and selenium, available phosphate, DTPA-extractable trace elements, and isotopically exchangeable zinc
Outcomes reported
The study reports concentrations of 29 mineral micronutrients in cereal grains and up to 84 soil chemistry properties from surveys across Ethiopia and Malawi. The dataset provides insights on geospatial variation in micronutrient concentrations in staple crops and their potential relationships with soil factors.
