7. Imaging water flow in soils and roots

Prof. Andrea Carminati (Georg-August-University Goettingen)

Plants need continuous and adequate supply of water from soils. How do plant roots can sustain the water demand set by transpiration, in particular when water becomes limited and heterogeneously distributed? This is a central question in hydrology and agriculture, in particular in times of climate change, when precipitation is expected to become more irregular and rare. Our understanding of...

16. Contribution of neutron imaging to assess key processes at the root-soil interface

Prof. Sascha Oswald (University of Potsdam)

Imaging with neutrons has been shown the last years to be a powerful and precise tool to address not only water content dynamics in soil and sediments, but also to identify and track root structures and root growth. The recent developments have seen a special focus on zooming into the root-soil interface, but also to broaden the perspective by introducing additional methodological procedures...

89. The influence of heterogeneous water and phosphorus supply on root growth in soil

Mr Bernd Felderer (ETHZ)

16/04/2012, 11:30

Phosphorus (P) and water are the two most limiting resources for plant growth in natural and agricultural ecosystems. Water and P distribution in soil varies over time and space and is heterogeneous on the scale of a root system. Temporal and spatial adaptation of root growth to these heterogeneities is crucial for nutrient and water uptake, plant fitness and plant production. Many plant...
