Wood Biomass Ash (WBA) from the Heat Production Process as a Mineral Amendment for Improving Selected Soil Properties

This research concerned the possibilities of natural management ash, which is a waste product obtained in process burning wood chips bio-heating plant. The basis was pot experiment, carried out greenhouse University Warmia and Mazury Olsztyn, Poland. experiment dealt with influence increasing doses biomass ash added to soil on selected properties. used for taken from arable layer (0–25 cm) soil. It characterized by acidic reaction, low salinity, an average content total carbon (TC). test plant corn. Soil analysis after harvest showed increase pH significant improvement sorption properties, without causing excessive salinity. In addition, available K, P, Mg observed, at highest dose WBA reached: 121.9; 109.3, 41.33 mg kg−1 soil, respectively. trace metals: iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), cadmium (Cd), lead (Pb), cobalt (Co), chrome (Cr), nickel (Ni) quite varied but did not exceed permissible values agricultural soils. forms these metals was, respectively, 1004, 129.9, 8.70, 2.08, 5.54, 0.195, 1.47, 0.97, 1.92 results confirmed fertilizing potential ash.
