E rather uniform rate of reduction in concen1 tration as urea solutions were percolated through some soils in the presence of toluene was taken as one criterion of the enzymatic nature of urea hydrolysis in soils. Additional types of evidence also support this concept (i, 2, 4, 5). Other soils, on the.other hand, exhibited rapidly accelerated rates of urea hydrolysis as percolations were continued. The suggestions offered that rapid multiplication of microorganisms during the percolation period even in the presence of the antiseptic, toluene, were not supported by the many tests iniposed (5). This paper pre-, sents additional data which may help to explain the accelerated rate of urea hydrolysis as percolations were continued.
