Nitrogen solutions and solid nitrogen fertilizer for barley and fodder beets

Nitrogen solutions and solid nitrogen fertilizer for barley and fodder beets. Fogh, H. T. (Statens Forsoegsstn., Askov, Den.). Tidsskr. Planteavl, 80(4), 556-68 (Danish) 1976. CODEN: TPLAAV. DOCUMENT TYPE: Journal CA Section: 19 (Fertilizers, Soils, and Plant Nutrition) At the Askov (sandy loam) and Lundgard (sandy soil) state exptl. stations field expts. were carried out to compare the effects of solns. and solid N fertilizer. The solns. used were NH4NO3 soln. (AN) contg. 16% N and urea-NH4NO3 soln. (UAN) contg. 30% N. As solid fertilizer calcium ammonium nitrate contg. 26% N was used. The fertilizers were applied to barley and fodder beets at sowing time, by bands at a depth of 10 cm and as top dressing with and without harrowing. No differences were found in grain yield between the 3 fertilizers, when they were applied as top dressings. The N solns. 15245-12-2 is also in the experiment. showed lower grain yield than did solid fertilizer, when the fertilizers were placed in bands in the soil. The yields of DM in fodder beets showed no significant differences in relation to the different fertilizers or methods of application. Both the content and the yield of total-N in grain and fodder beets were lower after the solns. than after the solid fertilizer. The application methods showed no differences in content and yield of total-N in grain, but with fodder beets UAN-soln. showed higher yield and content of N when placed than when top-dressed. On sandy soil banding of UAN showed a lower yield than did top dressing probably because of differences in leaching. On sandy soil in the next year there was a very low yield of fodder beets when fertilizers were top-dressed, because of a great redn. in the no. of plants, esp. where no harrowing had been done. .
