Abstract
An investigation on molecular absorption of urea by flooded rice was conducted at the Radio Tracer Laboratory , College of Horticulture, Vellanikkara, during the period 1990-1992. The effect of soil submergence on soil urease activity was also studied on five different soils of Kerala namely, laterite, kole, kari, kayal and black soils. An attempt was also made to develop an isotope method for urease estimation using 14c labelled urea . From the specific activity of 14c urea solution initially added and the count rates obtained for the KCI-PMA extract, the urea hydrolysis rate was calculated.
