Soil seal development under simulated rainfall: structural, physical and hydrological dynamics (2017)
Journal Article
Armenise, E., Simmons, R. W., Ahn, S., Garbout, A., Doen, S. H., Mooney, S. J., Sturrock, C., & Ritz, K. (2018). Soil seal development under simulated rainfall: structural, physical and hydrological dynamics. Journal of Hydrology, 556, https://doi.org/10.1016/j.jhydrol.2017.10.073

This study delivers new insights into rainfall-induced seal formation through a novel approach in the use of X-ray Computed Tomography (CT). Up to now seal and crust thickness have been directly quantified mainly through visual examination of sealed/...

Assessing water uptake in sugar beet (Beta vulgaris) under different watering regimes (2017)
Journal Article
Fitters, T. F., Bussell, J. S., Mooney, S. J., & Sparkes, D. L. (2017). Assessing water uptake in sugar beet (Beta vulgaris) under different watering regimes. Environmental and Experimental Botany, 144, https://doi.org/10.1016/j.envexpbot.2017.10.001

Sugar beet yield worldwide is substantially reduced as a result of drought stress. Water uptake may be limited by the plant (e.g. low root density) or by soil physical constraints. An experiment was conducted to assess the ability of sugar beet to pr... Read More about Assessing water uptake in sugar beet (Beta vulgaris) under different watering regimes.

Shaping 3D root system architecture (2017)
Journal Article
Morris, E. C., Griffiths, M., Golebiowska, A., Mairhofer, S., Burr-Hersey, J., Goh, T., von Wangenheim, D., Atkinson, B., Sturrock, C. J., Lynch, J. P., Vissenberg, K., Ritz, K., Wells, D. M., Mooney, S. J., & Bennett, M. J. (2017). Shaping 3D root system architecture. Current Biology, 27(17), R919-R930. https://doi.org/10.1016/j.cub.2017.06.043

Plants are sessile organisms rooted in one place. The soil resources that plants require are often distributed in a highly heterogeneous pattern. To aid foraging, plants have evolved roots whose growth and development are highly responsive to soil si... Read More about Shaping 3D root system architecture.

Quantification of root water uptake in soil using X-ray Computed Tomography and image based modelling (2017)
Journal Article
Daly, K. R., Tracy, S. R., Crout, N. M., Mairhofer, S., Pridmore, T. P., Mooney, S. J., & Roose, T. (2018). Quantification of root water uptake in soil using X-ray Computed Tomography and image based modelling. Plant, Cell and Environment, 41(1), 121-133. https://doi.org/10.1111/pce.12983

Spatially averaged models of root-soil interactions are often used to calculate plant water uptake. Using a combination of X-ray Computed Tomography (CT) and image based modelling we tested the accuracy of this spatial averaging by directly calculati...
