Summary
A method is described for the determination of concentration gradients in the vicinity of plant roots. Plants are grown in small containers in which the roots are separated from the soil by a screen of nylon cloth. Root hairs but not roots penetrate the screen into the soil. In order to investigate the rhizospheric soil, the soil is frozen by liquid nitrogen and sliced into layers about 0.06 mm thick by means of a refrigerated microtome.
