method for extracting plant roots from soil which facilitates rapid sample processing without compromising measurement accuracy

This study evaluates a novel method for extracting roots from soil samples and applies it to estimate standing crop root mass (± confidence intervals) in an eastern Amazon rainforest. Roots were manually extracted from soil cores over a period of 40 min, which was split into 10 min time intervals. T...
