Journal Article
Lark, R. M., Ander, E. L., & Broadley, M. R. (2018). Combining two national-scale data sets to map soil properties, the case of available magnesium in England and Wales: combining two soil surveys. European Journal of Soil Science, doi:10.1111/ejss.12743

Given the costs of soil survey it is necessary to make the best use of available data sets, but data which differ with respect to some aspect of the sampling or analytical protocol cannot be combined simply. In this paper we consider a case where two... Read More

A scanner-based rhizobox system enabling the quantification of root system development and response of Brassica rapa seedlings to external P availability (2017)
Journal Article
of root system development and response of Brassica rapa seedlings to external P availability. doi:10.3117/plantroot.11.16. ISSN 1881-6754

Rhizoboxes are soil-root compartments that may well provide the closest naturalistic conditions for studying root systems architectures (RSAs) in controlled environments. Rhizobox-based studies can however lead to mis-estimation of root traits due to... Read More
