Strict, three-year-long field experiment was performed on degraded Phaeozems, IIIb soil valuation class, with pH ranging from 6.5 to 7.1, of high richness in phosphorus and potassium, medium in magnesium, and low in sulphur. The experiment was carried out in a split-block design with two factors in four repetitions. The aim of the study was to evaluate the effect of various doses of nitrogen (0, 60,...
Field experiment was carried out in the Didactic and Experimental Department in Swadzim near Poznań, in years 2004-2005 (52°26’ N; 16°45’ E). The experiment was established in a „split-plot” design with two factors and four field replications. The primary factor consisted in three nitrogen doses: 0, 60, and 120 kg N·ha⁻¹, while the secondary factor included four doses of kieserite (magnesium sulphate):...
