... Since short-rotation coppice (SRC) energy plantations can be cultivated for 1520 years in the same field, balanced and regular nutrient supply is required in the soil to obtain good aboveground biomass yields (GYURICZA et al., 2008;SMART & CAMERON, 2012). Biomass yield of Salix spp., grown as an energy crop, can be stimulated by the application of various inorganic or organic fertilizers and additives in soil, including biosolids (e.g., municipal sewage sludge, compost), biochar or biomass ash (PULFORD et al., 2002;PARK et al., 2005;DIMITRIOU et al., 2006;SALETNIK & PUCHALSKI, 2019). Since municipal sewage sludge is not a balanced fertiliser in terms of plant nutrients (it contains mainly P and organically bound N, but very low amount of K), it could be advantegeous to mix it with wood ash that contains K and some P (DIMITRIOU et al., 2006;JAMA & NOWAK, 2012). ...
... 5 times more Ca (187,550 mg kg -1 d.m.), Mg (35,348 mg kg -1 d.m) and P (25,403 mg kg -1 d.m.) than MSS (SIMON et al., 2022). These values are in agreement with observations of other authors (PARK et al., 2005;DIMITRIOU et al., 2006;LAZDINA et al., 2011;SALETNIK & PUCHALSKI, 2019;WÓJCIK et al., 2020), who noticed that sewage sludge or wood ash is a rich source of Ca, Mg, P or K. The MSS contained significantly more Cr and Pb than WA, while WA contained more Zn ( Table 1) In Hungary the 50/2001 GOVERNMENT DECREE (2001) controls the agricultural utilization of sewage sludge. ...

Open-field small plot long-term experiment was set up during 2011 with willow ( Salix triandra × S. viminalis ‘Inger’), grown as a short rotation coppice energy crop in Nyíregyháza, Hungary. The sandy loam Cambisol with neutral pH was treated three times (2011, 2013, and 2016) with 15 t ha –1 municipal sewage sludge compost (MSSC) and with 600 kg ha –1 (2011, 2013) or 300 kg ha –1 (2016) wood ash (WA). In 2018 the MSSC-treated plots were amended with 7.5 t ha –1 municipal sewage sediment (MSS), and 300 kg ha –1 WA. MSSC and WA or MSS and WA were also applied to the soil in combinations during all treatments. Control plots remained untreated since 2011. Repeated application of wastewater solids (MSSC, MSS) and wood ash (WA) significantly enhanced the amounts of As (up to +287%), Ba, Cd (up to +192%), Cu, Mn, Pb, and Zn in the topsoil of willows. The combined application of MSSC+MSS+WA resulted in significantly higher Mn and Zn and lower As Ba, Cd Cr, and Pb concentrations in topsoil than MSSC+MSS treatment of soil without WA. Nitrogen concentrations in leaves of treated plants were generally slightly lower or similar to control. All soil treatments significantly enhanced the uptake or accumulation of nutrient elements (Ca, K, Mg, P) and potentially toxic elements (As, Ba, Cd, Cr, Cu, Mn, Ni, Pb, and Zn) in the leaves of willows during 2018, 2019, and 2020. Significantly higher Mn or Zn concentrations were measured in MSSC+MSS+WA than in MSSC+MSS treatments. Significant amounts of Cd (up to 1.11 mg kg –1 ) or Zn (up to 183 mg kg –1 ) can be translocated (phytoextracted) from a soil amended with wastewater solids or wood ash to willow leaves. In 2018 the treatments decreased the chlorophyll fluorescence values, while in 2019 and 2020 the light adapted fluorescence yield (Y) values were higher in treated than in control plants.

... It was found that the average concentration of the chemical elements was the same in the roots and trunk but was much higher in the leaves of the energetic willow. Saletnik and Puchalski [20] studied the effect of fertilizers (ash and biochar) on the production of wood biomass in the case of Osier willow (Salix viminalis). It was found that, in the case of fertilization with different concentrations of ash and biochar, biomass production values of 2.6 and 3.01 t/ha were highlighted respectively, compared to a control soil that produced 2.29 t/ha. ...

The paper presents some forestry aspects of using Inger and Tordis willow clones to obtain woody biomass and remedy degraded soils. The methodological aspects regarding the planting of willow seedlings, the evaluation of the survival rate, the evaluation of the biomass quantity and the enrichment of the soil are analyzed. The results of the experiments showed that the degraded soil decreased the viability rate of the cuttings by 16.6% for the Tordis clone and 35.8 for the Inger clone. The analysis of the soil samples showed that it was enriched in nutrients after 2 years of cultivation, by the decomposition of the fallen leaves on the soil and by the absorption of the substances from the soil. Regarding the amount of biomass, its mass per hectare after the first year of cultivation was 0.64 t/ha for the Inger clone and 0.66 t/ha for the Tordis clone, while the calorific values of 19,376 kJ/kg for Inger and 19,355 kJ/kg for Tordis were good values. The final conclusion of the paper highlights that Osier willow is a viable solution for obtaining energetic biomass and putting it back into the productive circuit of degraded soils.
... A properly selected dose of biomass ash can improve the chemical properties of soil, including its pH, increase the content of available forms of macroelements and microelements for plants, and reduce the concentration of mobile forms of heavy metals, such as Pb and Cd [28]. Deacidification of soil caused by ash is a consequence of the content of potassium, calcium and magnesium oxides in this substance [29,30]. ...

The purpose of this study was to evaluate the effect of ash from combustion of plant biomass of energy willow and Pennsylvania fanpetals on yields of willow grown as an energy crop and on soil properties. A three-year pot experiment was carried out on substrates with a loamy sand texture. Ash application rates were based on the potassium fertilisation demand. An incubation experiment was carried out to determine the effect of biomass-based ash on soil properties. Three soils with textural categories were incubated for 3 months with the ashes, the doses of which were determined on the basis of the hydrolytic acidity of soils (¼; ½ and 1.0 Hh). It was found that ashes generated from burning willow or Pennsylvania fanpetals can be applied instead of phosphorus, potassium and magnesium fertilisers in the cultivation of energy willow. The plant uptake of P, K and Mg from the ashes did not diverge from their absorption by plants when supplied with mineral salts. The application of these alkaline ashes will increase the soil content of phytoavailable forms of phosphorus, potassium and magnesium. The examined ashes enriched the soil with micronutrients.

This article presents the results of a two-year study investigating the effects of the fertilization of soil, with biochar and ash from plant biomass, on selected properties of the pyrolysis products obtained from basket willow (Salix viminalis L.) and giant miscanthus (Miscanthus x giganteus). The study was designed to determine whether soil enrichment through the use of organic fertilizers (ash added at the rate of 1.5 t ha −1 , biochar added at the rate of 11.5 t ha −1 and a combination of them) in the cultivation of energy crops would affect the quality of pyrolysates obtained from these plants. The research goal was to use biochar and biomass ash to produce high-quality pyrolysates with fertilizing potential. The aboveground parts of the plants were subjected to the pyrolysis process, which was carried out in constant conditions, i.e., a temperature of 500 °C and duration of 10 min. The pyrolysates obtained were examined for their pH value, the content of absorbable forms of phosphorus (P2O5), potassium (K2O) and magnesium (Mg), as well as total carbon and the total content of selected macro-and micro-elements. The results of the current study show the beneficial effects of these soil fertilizers, reflected by the high quality and enhanced mineral contents of the biochars obtained. The highest total increase in the contents of absorbable forms of P, K and Mg was found in the pyrolysis products from basket willow fertilized with ash alone, amounting to 21.6% in relation to the pyrolysates from the control sample. As for the pyrolysates from the biomass of giant miscanthus, the greatest total increase in the contents of the elements, amounting to 44.4%, was identified when biochar and ash were used in combination. Soil amendments such as biochar and ash used for growing bioenergy crops can alter the aboveground plant quality. The subsequent pyrolysates created from these plants may be enriched and can be an alternative to mineral fertilizers. Natural amendment, such as high-quality pyrolysates, can be used in the cultivation of many plants. Additionally, conversion of plant biomass into pyrolysates is important for the environment, affecting the balance of carbon in the atmosphere through its capture and storage in a stable form outside the atmosphere, e.g., in soil.
