The aim of the paper was to assess the efficiency of using fertilizer produced from FGD gypsum and fluidized bed combustion ashes (as combustion by-products at coal power plants) in crop production. The scope of work included laboratory analyses to examine the material for the content of macro- and microelements, and a vegetation experiment to determine its effect on the amount and quality of spring wheat yield and spring rape yield. Moreover, the study determined the impact of the analyzed material on selected physicochemical and chemical properties of soil. The research goal was accomplished through a vegetation experiment conducted in 2016 on brown soil made of loess. The experiment comprised five treatments which were repeated four times for each cultivated plant. The test plants included spring wheat cv. Monsun and spring rape cv. Belinda. The experiment scheme included the following treatments: control treatment I—without fertilization, II—with mineral fertilization, and three treatments with different levels of the fertilizer and a constant level of NPK fertilization. Calcium content in the investigated product was at the level of 34.2% CaO, sulfur—23.8% SO3, and iron—1.1%. The heavy metal content was below critical values for fertilizers or plant growth promoters specified in the Polish Act of 10 July 2007 on fertilizers and fertilization. The test results did not show any effects of the investigated product on soil reaction or on the content of available forms of calcium, phosphorus, potassium, magnesium and total content of nitrogen and carbon. However, in the treatments where the analyzed material was applied, we found an over three times higher sulfate sulfur content in the soil compared to the control treatment I and II. The investigated material did not influence the amount of plant yield. In the treatments with successive levels of the mixture of FGD gypsum and fluidized bed combustion ashes, we found a 20% increase in sulfur content in the wheat grain compared to the control treatments. In the case of rape, we found a 40% increase in sulfur content. The obtained results showed great fertilizing potential of the examined coal combustion by-products.
