The addition of lime and gypsum to wood ash and straw ash were used in the studies. The subject of the study was estimation of the fertilization effect of biomass, ash, gypsum and lime on the content of macro- and microelements in soil and grain of spring wheat. The experiment was carried out in 2016 in the West Pomeranian Voivodeship in Poland. The study compared three factors: wood ash of deciduous and coniferous trees and cereal straw ash (I. factor), two types of ash additions: lime or gypsum (mixture composition: 60% ash and 40% lime or gypsum) (II. factor), three doses of ash with lime or gypsum mixture: 2, 4, 6 Mg·ha−1 and control (III. factor). The analysis of the microelements contents (copper, chromium, nickel and lead) in the soil shows that the application of fertilizer in a form of wood or straw ash as well as PROFITKALK lime or SulfoPROFIT gypsum did not exceed the threshold values for the soil from the first group of land specified in Regulation of the Minister of the Environment of September 1, 2016 on the manner of assessing the pollution of the earth’s surface. After application of biomass ashes (wood or straw) an increase of some macroelements (potassium, phosphorus and calcium) in the soil was observed. The experiment did not reveal any influence of applied fertilization in the form of wood or straw ash nor PROFITKALK lime nor SulfoPROFIT gypsum on changes in iron, manganese and zinc abundance in grains of spring wheat.


The aim of this research was to assess the use of biomass ash for fertilisation of mineral soil. The study involves the analysis of the effects of biomass ash applied to soil on the changes of pH and the content of the available forms of phosphorus, potassium and magnesium as well as on total content of zinc, copper, manganese, nickel, cadmium and lead. The field experiment was conducted in 2013 in Duninowo near Ustka. In experiment grown two plants spring: Spring barley - var. Sebastian, and wheat - var. Bombona. The use of ash from biomass and Biotop compost as fertilisers did not result in any significant changes of soilpH. The use of ash from biomass and Biotop compost caused a significant increase in the contents of available phosphorus, potassium and magnesium in soil. The threshold values of the analysed trace elements in soil, as specified by the Regulation of the Minister of Environment, were not exceeded in any of the fertilising variants in the experiment.
