The relation between urease activity and bacterial biomass has been studied in soil incubation experiments and the results obtained are discussed with respect to the use of physiological methods for the biomass calculation. A high correlation between both tested parameters has been found in the absence of fresh organic matter input into the soil. However, the correlation disappeared after soil enrichment with the substrates stimulating the growth of zymogenous bacteria, among them of ureolytic bacteria
