    Abstract

    A non-buffer method study with 3 soils showed that urea hydrolysis followed a zero order kinetics at least up to 12 hours. The urea hydrolysis rate coefficient (k2) of the soils ranged from 0.083 to 0.167 mu moles/g soil hr-1 and remained fairly constant for each soil during the 12 hours of study of urease activity. The urease activity of the soils varied from 5.1 to 10.0 mu g urea hydrolysed/g of soil hr-1 and increased with increase in soil organic carbon content.
