“…At the end of the second year the findings showed a decrease in the mean total contents of macro-elements in the biomass of willow leaves and stems, compared to the previous year. The plant biomass collected was characterised by the highest contents of Ca, P, and K. High levels of calcium and potassium in one-year stems of basket willow were also identified by Otepka and Haban [86] in a long-term study of effects produced by wood ash in basket willow growth as well as by Borkowska and Lipiński [87] in a study focusing on the contents of macro-and micro-elements in energy crop biomass.…”

The article presents the findings of a field experiment investigating the effectiveness of biochar and plant biomass ash when used as a soil fertiliser in the cultivation of basket willow (Salix viminalis L.). The purpose of the study was to determine the optimal dose of fertiliser to enable a maximum increase in the crop yield and enhancement of the chemical properties of the soil. In the course of the two-year experiment, the increase in basket willow yield was in the range of 6%–49%. The highest dry matter yield from the plants, at the end of both the first and the second year of the experiment, was obtained in the plots where the soil was amended with biochar alone (11.5 t ha−1), a combination of biochar and ash (respectively 11.5 and 1.5 t ha−1) and ash added at the rate of 1.5 t ha−1. The yield was reduced when the soil was amended with ash added at the rates of 3.0 t ha−1 and 4.5 t ha−1 or with the latter doses of ash combined with biochar. The results indicated that too high a concentration of ash (rate of 3.0 t ha−1 or higher for basket willow) have negative effects on plant growth and may represent a limiting factor. The study suggests that biochar is a better soil amendment than ash, because biochar application gave the highest improvement in the soil properties and plant growth. It was found that the addition of biochar, biomass ash or combinations of the two materials applied in suitable doses may be a good soil amendment.. In particular in soils which are severely damaged and require restoration, this fertilization may have a noticeable effect on soil properties and plant growth.

“…For example, in the Netherlands, it is forbidden to use biomass ash as a forest fertiliser; in Austria, the addition of 2 wt.% of bio ash is allowed in compost materials (van Ejik et al, 2012). In Slovakia, wood ash use is allowed only for scientific purposes (Otepka and Habán, 2013). In Finland and Denmark, the use of bio ash as a fertiliser is regulated by national legislation (Finnish Ministry of Agriculture and Forestry, 2011; Danish Ministry of the Environment, 2008a).…”

The current growth strategy and environmental legislation of the European Union both aim to increase the amount of renewable energy and to improve the use of waste streams. These policies mean there will be an increasing need to utilise bio ash. Currently Finland and Denmark are the only European countries with specific national legislation concerning bio ash use. Sweden has recommendations concerning the use of bio ash fertilisers. Besides having different limit values for harmful elements and nutrients in ash fertilisers, all these countries have different digestion methods that are allowed for element content determinations. This study compared the results of the five digestion methods (aqua regia, nitric acid, nitric/hydrochloric acids, nitric/hydrochloric/hydrogen fluoride acids, and lithium tetraborate fusion) established by Nordic authorities. Two Finnish peat-wood fly ash samples were studied. Our results indicate that the choice of digestion methods produces a significant difference in the obtained heavy metal or nutrient concentration of bio ash, especially regarding the potassium concentration.
