Role of inhibitors and biodegradable material in mitigation of nitrogen losses from fertilized lands

Loss of N, occurring mainly through NH3 volatilization, biological denitrification, and NO3 - leaching, has both economic and environmental implications. Therefore, the economic benefits of reduced environmental pollution and future damage to our environment as a result of the use of urease inhibito...
