Root mapping of upland rice to access potential root extraction ratio in soil

Dusserre J., Rakotoarivelo M., Autfray P., Chopart J.L.. 2015. In : ISRR-9 Roots Down Under. Canberra : International Society of Root Research, 1 poster. Symposium of the International Society of Root Research. 9, 2015-10-06/2015-10-09, Canberra (Australie).

A better understanding of the effects of agronomic management on soil resource accessibility is needed to improve upland rice cropping systems. Here we investigated a new indicator: the potential root extraction ratio (PRER) which takes into account the overall spatial variability of root distribution in soil profiles.
