Abstract

The isolation of crop roots from soil samples, making use of the dispersing action of CO2 evolved by the reaction of added oxalic acid on carbonates in the soil was described. The roots were photographed in a thin layer of water against a matt black background, resulting in sharp negative pictures that can be used by a Quantimet image analyser to measure length or other properties embodied in the photographs. The methods were applied in a study of the rooting characteristics of potato crops in a rotation experiment. (Abstract retrieved from CAB Abstracts by CABI’s permission)
