Assessing land suitability for rainfed paddy rice production in Zambia (2021)
Journal Article

Rice is one of the staple food crops and is a profitable smallholder cash crop in Zambia. It has the potential to contribute significantly to increased incomes and employment among rural producers. However, rice is the only staple crop in the country... Read More about Assessing land suitability for rainfed paddy rice production in Zambia.

Ten challenges for the future of pedometrics (2021)
Journal Article

Pedometrics, the application of mathematical and statistical methods to the study of the distribution and genesis of soils, has broadened its scope over the past two decades. The primary focus of pedometricians has traditionally been on spatial and s... Read More about Ten challenges for the future of pedometrics.

A comparison between three legacy soil maps of Zambia at national scale: The spatial patterns of legend units and their relation to soil properties (2021)
Journal Article

We examined three soil maps of Zambia, two published at scales of 1:1 million – the Exploratory Soil Map of Zambia (ESMZ) and the Vegetation–Soil Map produced by Trapnell and colleagues in 1947 – and one at 1:3 million, the Soil Atlas of Africa (SAA)...

The nutritional quality of cereals varies geospatially in Ethiopia and Malawi (2021)
Journal Article

Micronutrient deficiencies (MNDs) remain widespread among people in sub-Saharan Africa where access to sufficient food from plant and animal sources that is rich in micronutrients (vitamins and minerals) is limited due to socioeconomic and geographic... Read More about The nutritional quality of cereals varies geospatially in Ethiopia and Malawi.

Communicating uncertainties in spatial predictions of grain micronutrient concentration (2021)
Journal Article

The concentration of micronutrients in staple crops varies spatially. Quantitative information about this can help in designing efficient interventions to address micronutrient deficiency. Concentration of a micronutrient in a staple crop can be mapp... Read More about Communicating uncertainties in spatial predictions of grain micronutrient concentration.

Performance of linear mixed models and random forests for spatial prediction of soil pH (2021)
Journal Article

Digital soil maps describe the spatial variation of soil and provide important information on spatial variation of soil properties which provides policy makers with a synoptic view of the state of the soil. This paper presents a study to tackle the t... Read More about Performance of linear mixed models and random forests for spatial prediction of soil pH.

Long‐term zero‐tillage enhances the protection of soil carbon in tropical agriculture (2021)
Journal Article

Contrasting tillage strategies not only affect the stability and formation of soil aggregates but also modify the concentration and thermostability of soil organic matter associated with soil aggregates. Understanding the thermostability and carbon r... Read More about Long‐term zero‐tillage enhances the protection of soil carbon in tropical agriculture.

Zinc deficiency is highly prevalent and spatially dependent over short distances in Ethiopia (2021)
Journal Article

Zinc (Zn) is an essential nutrient for human health. In Ethiopia, a high prevalence of Zn deficiency has been reported. To explore demographic variation and spatial dependencies in the Zn status of the Ethiopian population, we analyzed archived serum... Read More about Zinc deficiency is highly prevalent and spatially dependent over short distances in Ethiopia.

Crop uptake of heavy metals in response to the environment and agronomic practices on land near mine tailings in the Zambian Copperbelt Province (2021)
Journal Article

© 2021, The Author(s), under exclusive licence to Springer Nature B.V. part of Springer Nature. A field experiment was undertaken on farmers’ fields adjacent to a large mine tailings dam in the Zambian mining town of Kitwe. Experimental plots were lo...

Spatial variability and mapping of soil fertility status in a high-potential smallholder farming area under sub-humid conditions in Zimbabwe (2021)
Journal Article

© 2021, The Author(s). A study was conducted to examine spatial variability of soil properties related to fertility in maize fields across varying soil types in ward 10 of Hurungwe district, Zimbabwe; a smallholder farming area with sub-humid conditi... Read More about Spatial variability and mapping of soil fertility status in a high-potential smallholder farming area under sub-humid conditions in Zimbabwe.

To till or not to till in a temperate ecosystem? Implications for climate change mitigation (2021)
Journal Article

The management of agricultural soils affect the composition and scale of their greenhouse gas (GHG) emissions. There is conflicting evidence on the effect of zero-tillage on carbon storage and GHG emissions. Here we assess the effects of zero-tillage...

Mapping groundwater recharge in Africa from ground observations and implications for water security (2021)
Journal Article

© 2021 British Geological SurveyUKRI. Published by IOP Publishing Ltd. Groundwater forms the basis of water supplies across much of Africa and its development is rising as demand for secure water increases. Recharge rates are a key component for asse...

Can nitrogen fertilizer management improve grain iron concentration of agro-biofortified crops in Zimbabwe? (2021)
Journal Article

Improving iron (Fe) concentration in staple grain crops could help reduce Fe-deficiency anaemia in communities dependent on plant-based diets. Co-application of nitrogen (N) and zinc (Zn) fertilizers has been reported to improve both yield and grain...
