Abstract
The paper presents the results of the elemental composition of the ash produced during combustion of straw and hay. Test samples of ash were characterized by alkaline pH (pH 10.2) and a substantial overall potassium content (155,7 g∙kg-1 K), calcium (124,0 g∙kg-1 Ca), phosphorus (15,1 g∙kg-1 P) and magnesium (7,3 g∙kg-1 Mg). In addition, presence of essential micronutrients for plants was found in them (Fe > Mn > Zn > Cu). A small natural content of heavy metals (Cr > Pb > Ni > Cd > Hg) in the ash is not a contraindication for the agricultural use of ash from the plant biomass.
