© 2019, The Author(s). Aim: Magnesium (Mg) deficiency (known as grass tetany) is a serious metabolic disorder that affects grazing ruminants. We tested whether Mg-fertiliser can increase Mg concentration of Italian ryegrasses (Lolium multiflorum L.)...

Urine selenium concentration is a useful biomarker for assessing population level selenium status (2019)
Journal Article
Phiri, F. P., Ander, E. L., Lark, R. M., Bailey, E. H., Chilima, B., Gondwe, J., …Broadley, M. R. (2020). Urine selenium concentration is a useful biomarker for assessing population level selenium status. Environment International, 134, Article 105218. https://doi.org/10.1016/j.envint.2019.105218

Plasma selenium (Se) concentration is an established population level biomarker of Se status, especially in Se-deficient populations. Previously observed correlations between dietary Se intake and urinary Se excretion suggest that urine Se concentrat...

Boundary line models for soil nutrient concentrations and wheat yield in national-scale data sets (2019)
Journal Article
Lark, R., Gillingham, V., Langton, D., & Marchant, B. (2020). Boundary line models for soil nutrient concentrations and wheat yield in national-scale data sets. European Journal of Soil Science, 71(3), 334-351. https://doi.org/10.1111/ejss.12891

In boundary line analysis a biological response (e.g. crop yield) is assumed to be a function of a variable (e.g. soil nutrient concentration) which limits the response in only some subset of observations because other limiting factors also apply. Th... Read More about Boundary line models for soil nutrient concentrations and wheat yield in national-scale data sets.

Review: mine tailings in an African tropical environment—mechanisms for the bioavailability of heavy metals in soils (2019)
Journal Article

© 2019, Springer Nature B.V. Heavy metals are of environmental significance due to their effect on human health and the ecosystem. One of the major exposure pathways of Heavy metals for humans is through food crops. It is postulated in the literature...

The risk of selenium deficiency in Malawi is large and varies over multiple spatial scales (2019)
Journal Article
Phiri, F. P., Ander, E. L., Bailey, E. H., Chilima, B., Chilimba, A. D. C., Gondwe, J., …Broadley, M. R. (2019). The risk of selenium deficiency in Malawi is large and varies over multiple spatial scales. Scientific Reports, 9(1), Article 6566. https://doi.org/10.1038/s41598-019-43013-z

Selenium (Se) is an essential human micronutrient. Deficiency of Se decreases the activity of selenoproteins and can compromise immune and thyroid function and cognitive development, and increase risks from non-communicable diseases. The prevalence o... Read More about The risk of selenium deficiency in Malawi is large and varies over multiple spatial scales.

This landmark paper by Burgess & Webster (1980a) signalled a new era in the spatial mapping of the soil. The emergence of pedometrics as a distinct subdiscipline of soil science was a gradual process, and had its roots in earlier studies than this on...
