Extract

Three field trials with Italian ryegrass showed that solid N fertilizers usually gave larger yields than solutions containing 5% N but the differences were significant in only three of thirteen comparisons. More N was taken up from solid fertilizers than from solutions; the differences were not significant at 561b N/acre but were at 1121b N/acre. Grass given solutions had smaller percentage of N and the differences in the percentage of N were significant in eight of ten comparisons. In pot experiments with Italian ryegrass, solutions containing 3.3% N were less effective than solid fertilizers, but solutions containing 1.8% N were equally effective. Possible causes of solutions being less effective are discussed.
