Root tip shape governs root elongation rate under increased soil strength

T Colombi, N Kirchgessner, A Walter, T Keller - Plant Physiology, 2017 - academic.oup.com
Increased soil strength due to soil compaction or soil drying is a major limitation to root
growth and crop productivity. Roots need to exert higher penetration force, resulting in …

Decreased burrowing activity of endogeic earthworms and effects on water infiltration in response to an increase in soil bulk density

Y Capowiez, S Sammartino, T Keller, N Bottinelli - Pedobiologia, 2021 - Elsevier
Endogeic earthworms live and burrow in the soil to find their food. They burrow by pushing
the soil aside or ingesting it and are thus sensitive to soil compaction. However there is a …
