Selenium biofortification of crops on a Malawi Alfisol under conservation agriculture (2020)
Journal Article

© 2020 Elsevier B.V. Biofortification with selenium (Se) may rely on rapid uptake by crops, following application, to offset progressive fixation into unavailable organic forms of Se in soil. A biofortification study was conducted on an Alfisol withi... Read More about Selenium biofortification of crops on a Malawi Alfisol under conservation agriculture.

Short-Term Iodine Dynamics in Soil Solution (2020)
Journal Article

Assessing the reactions of iodine (I) in soil is critical to evaluate radioiodine exposure and understand soil-to-crop transfer rates. Our mechanistic understanding has been constrained by method limitations in assessing the dynamic interactions of i... Read More about Short-Term Iodine Dynamics in Soil Solution.

Can selenium deficiency in Malawi be alleviated through consumption of agro-biofortified maize flour? Study protocol for a randomised, double-blind, controlled trial (2019)
Journal Article

© 2019 The Author(s). Background: Micronutrient deficiencies including selenium (Se) are widespread in Malawi and potentially underlie a substantial disease burden, particularly among poorer and marginalised populations. Concentrations of Se in stapl... Read More about Can selenium deficiency in Malawi be alleviated through consumption of agro-biofortified maize flour? Study protocol for a randomised, double-blind, controlled trial.
