Technology for production of NS fertilizers by compacting method and their impact on the grain crop and quality of winter wheat cereals. Technologia otrzymywania nawozów typu NS metodą kompaktowania oraz ocena wpływu tych nawozów na plonowanie i jakość ziarna pszenicy ozimej


  NH4)2SO4 and urea 1:1 mixts. (grain size fractions up to 4 mm) were compacted under 5-15 kN/cm2 (50-150 MPa), studied for d. and compression strength (after grinding), and then used for fertilizing fields (N dose 120 or 200 kg/ ha) where winter wheat was cultivated. For comparison, solid urea and optionally S-contg. solns. of NaNO3 and urea were used as fertilizers. The grain crop of winter wheat and gluten content in the cereal grains were detd. Use of the new (NH4)2SO4-urea fertilizer did result neither in higher wheat grain crop nor in a significantly higher gluten content in the cereals when compared to other fertilizers used except for the high N dose (200 kg/ha) of the new fertilizer. Podjęto badania nad technologią otrzymywania nawozów typu NS1, 2) z mocznika i siarczanu amonu metodą kompaktowania, a następnie próbne partie nawozów poddano ocenie rolniczej. [...]
