Department of Primary Industry and Fisheries 40 required, usually spot spraying for broadleaf weed control. Some grass only paddocks are boom-sprayed with Starane/2.4-D mixtures if broad leaf weeds are prominent. Paddock 52 Oolloo/Arhnem was sprayed to control Sida, but Oolloo was eliminated as well. A single application of 100 kg/ha urea was applied to paddock 45 (Pangola) and paddock 46 (Sabi) because they had shown symptoms of deficiency in previous years. The animals are supplemented with ad-lib Uramol blocks during the Dry season and with Phosrite blocks in the Wet season. Intake is recorded monthly. Cattle were weighed monthly, given a condition score and P8 (rump) fat was measured, starting in late December and continued till the end of the grazing year in June 2001. Pasture composition and yield were assessed twice during the year, in early Wet season and during December 2000. A post-Wet season assessment was made during May 2001. Paddock 50 was sown with a range of legume species to determine the most appropriate to complement the existing buffel grass (see Project Pasture Species Evaluation under Grazing at DDRF - Paddock 50). First grazing of re-established Paddocks 48 and 50commenced in July 2000. Paddock 48 contains three rows of Cunningham and three rows of cv Taramba leucaena, which were slashed in November 2000 to a height of 30 cm and destocked till January 2001. Each row is half the paddock in length. Paddock 50 contains four blocks of multiple plots of five legumes sown into buffel grass during December 1999. It was grazed continuously throughout July 2000 June 2001. Table 1.
