Urea hydrolysis was complete in 1 day and 2 days in the Vertisol (pH 8.35) and one Alfisol (pH 6.20), resp.; in the second Alfisol (pH 4.50), urea hydrolysis was not complete 10 days after urea addition. Volatilization of ammonia was greatest in the Vertisol (14% of added urea-N); in all soils volatilization had peaked by day 2. Nitrification in the soils was positively correlated with pH. The results are discussed.","1992","published",,"Journal of the Indian Sociely of Soii Science","40","2","Indian Sociely of Soii Science",,"368-370",,,,,,,,,,,"TRUE",,"0019-638X",,,,,,"","http://indianjournals.com/ijor.aspx?target=ijor:jisss&volume=40&issue=2&article=031","http://scholar.google.co.in/scholar?hl=en&q=allintitle%3A+%22Transformations+of+Surface-applied+Urea+in+Three+Soils+of+Varying+pH%22&btnG=Search&as_sdt=0%2C5&as_ylo=&as_vis=0","author",,"","",,,,,,"",,,,,,,"",,,,,"",,,,,"","",,,,,"","",,,,,
