Present paper analyzes the effect of biomass ash and lime fertilization on changes in macro- and microelements content in soil and in winter wheat grain of RGT Kilimanjaro cv. (Triticum aestivum var. Kilimanjaro). Fertilization with wood or straw ash had no influence on changes in the pH and content of organic carbon, nitrogen and available phosphorus in the soil from experiment. As a result of fertilization with ash from wood or straw, a significant increase in the soil abundance was achieved in relation to: available potassium and exchangeable calcium. Increasing the dose was a factor that resulted in even higher efficiency of fertilizers. Analysis of the content of microelements in the soil (copper, chromium, nickel and lead) shows that the application of fertilization in the form of wood or straw ashes and lime PROFITKALK did not exceed the threshold values for soil from the first group of ground Results concerning the impact of ashes from wood or straw and lime PROFITKALK on changes in the content of macro- and microelements indicate that when cultivating wheat of Kilimanjaro cv., it is justified to use them as a fertilizing material
