Abstract
The aim of the study was to determine the effect of three new solid fertilisers (based on Salmag®) with innovative IDHA chelate additives (Cu, Mo and Fe) on the yield, yield (grain, straw), biometric characteristics and chemical composition (total N, Ca, Mg and Cu, Mo, and Fe) of spring wheat and soil properties in the pot experiment. The nitrogen dose in all fertilised plots was 140 mg kg−1 of soil (60% before sowing, 40% at tillering). Before sowing, uniform fertilisation with phosphorus (60 mg kg−1 of soil) and potassium (60 mg kg−1 of soil) were also applied. At the stem elongation stage, nitrogen fertilisers, especially Salmag® with Cu, promoted an increase, and Salmag® with Mo and Fe promoted a decrease in leaf greenness at other growth stages of spring wheat. All nitrogen fertilisers had a positive effect on height (especially Salmag® and Salmag® with Mo) and yield (especially Salmag® with Cu and Mo) of spring wheat grain and straw. The effect on grain yield was stronger, while Salmag® with Fe was slightly weaker than pure Salmag®. All applied nitrogen fertilisers increased total N in grain and straw and Ca and Mg in spring wheat straw. Nitrogen fertilisers enriched with micronutrients generally had a weaker effect than Salmag® on the content of total N in grain (in contrast to straw) and Ca and Mg. The addition of Cu, Mo, and especially Fe chelates increased the content of chelated elements in spring wheat, especially in straw. The pH value of the soil after harvest of spring wheat was slightly higher after the application of Salmag® and lower in the soil fertilised with Salmag® with Mo and Salmag® with Fe than in the control. Salmag® and Salmag® with Cu showed a significant increase in soil Mg and all nitrogen fertilisers (especially Salmag® with Fe) in soil Ca content after spring wheat harvest. Salmag® with Cu caused the greatest increase in soil Cu content. The new fertilisers with Mo chelate and especially with Cu chelate showed a significant effect on yield formation and quality of spring wheat.
