Soil samples of cultivated pots were collected at different intervals of days from 1 st to 37 th to examine the urease enzyme activity. Cultivated soil samples were put in plastic bags and tagged properly. Then depending upon the subsequent analysis samples and avoid any type of contamination, samples were kept under cool conditions until further analysis. The fresh soil samples received in the laboratory were dried in wooden or card trays in the air. These trays were numbered, and care was taken to maintain the identity of each sample at all stages of preparation. After that sample containing trays were dried placed in racks in a hot air cabinet at 35 °C and humidity of 30-60%. In general, excessive oven-drying of the soil affects the availability of most of the nutrients present in the sample, therefore samples were dried in hot air instead of oven to maintain the total N content, NH4 +, and NO3 content in the soil samples.
