The use of ATP to measure biomass C in soil is far more uncertain. A high diversity of applied techniques for the extraction and measurement of ATP has led to biomass C : ATP ratios which vary between about 150 and 1 000. Our own current investigations are expected to shed more light on the problems of ATP extraction.
