| Abstract/Contents: | "Urea, the major N source of world agriculture involves a serious urea-N loss through NH3 volatilization. Approaches to decrease N loss include using urease inhibitors in view of the environmental protection and the increase of urea-N efficiency. The purpose of laboratory researches was to assess the potential value of urease inhibitors to increase urea-N efficiency in soil and Kentucky bluegrass (Poa pratensis L.) turf. The activity of urease inhibitors Phenylphosphorodiamidate (PPD) and N-(n-butyl) thiophosphoric triamide (NBPT) measured to break-down ammonia volitalization. The soil and turf used in this project were from the fairway in one of the Korean golf course[s]. The researches were carried out for two weeks to measure the urease activities on urea hydrolysis under four temperatures (10-40°C) and for one week on turfgrass using forced-draft system. Results indicated that Urea-N involves considerable loss through gaseous NH3 by urease activities in plant-soil systems. Urease inhibitors PPD and NBPT have potential value for increasing N use efficiency by reducing NH3 volatilization. NBPT deserves further evaluation as fertilizer amendment than PPD use of urea turf industries." |
