Abstract/Contents:"Various slow-release nitrogen sources were used to fertilize 'Merion' Kentucky bluegrass (Poa pratensis L.) for two growing seasons, Slow-release sources were ureaform, activated sewage sludge, ADM (a coated urea), Urex (a urca-paraffin product), and IBDU (isobutylidene diurea). Response to fertilization was measured by weekly determinations of clippings yield and color rating. Urex performed similarly to ADM, and respons efollowing application was quicker and greater than that from ureaform, sewage sludge, and IBDU. IBDU showed good controlled release characteristics, but initial response after fertilization was slow. Residual effects of IBDU gave green color earlier in the spring than other treatments. Nitrogen recovery in the clippings was determined. Recovery ranged from 54% for ADM to 22% for ureaform over the 2-year period. Recovery from sewage sludge was 27%. The highest recoveries for IBDU and Urex treated plots were 46% and 52%, respectively. Recovery from a urea treatment was 52%"
