The influence of soil water content on the uptake of ions by roots. I. Soil water content gradients near a plane of onion roots.

Published online: 01 Jan 1973

Authors: Dunham, R. J. & Nye, P. H.

Content type: Journal article

Journal title: Journal of Applied Ecology

Water content and ion concentration gradients were measured in soil near a plane of onion seedling roots. Using the water content-matric potential rel...

Concentration gradients of phosphate, K, Ca and Mg were measured near a plane of onion seedling roots at a range of soil water contents, in a special ...

The influence of soil water content on the uptake of ions by roots. II. Chloride uptake and concentration gradients in soil.

Published online: 01 Jan 1975

Authors: Dunham, R. J. & Nye, P. H.

Content type: Journal article

Journal title: Journal of Applied Ecology

At higher soil water contents, chloride uptake by onion roots was greater, and the zones of depletion extended further. Models of ion transport were d...
