Description
Research was conducted during 2 growing seasons to determine N and S fertiliser recovery of Coastal bermudagrnss (Cynodon dactylon (L.) Pers.) on ft $-deficient Rilla silt loam (fine-silty, mixed, thcrmic Typic Hnpludalf) soil in the Gulf Coastal Plain of the south-eastern USA, S wns applied as gypsum or wettable S at the annual Initiation of fornge growth at 100 kg S/ha, N wu applied as ammonium nitrute (NH4NO3),_ urea, and 32% urea-ammonium nitrate (UAN) solution at rates of 0, 224, and 448 kg N/ha in 4 split applications. N sources did not significantly influence Nor S recovery. However, both N and S sources did significantly interact with N rates to affect N and S recovery. N recovery declined with increasing N rates but was significantly higher when coupled with S fertiliser, S recovery increased with increasing N rates, with higher recoveries for gypsum than for wettable S.
