Abstract:

The present study investigated the effects produced in the soil by municipal sewage sludge and wood ash applied during the cultivation of Jerusalem artichoke. The impact of the presence of applied the fertilizer materials on changes in soil and a macro- and microelements contents were investigated. The comparative analyses took into account 3 factors; the first factor – 4 levels of wood ash – 0; I–4.28; II–8.57; III–12.85 t ha-1, the second factor – 2 levels of sewage sludge – 0; 1 – 30.3 t ha-1, the third factor – 2 varieties of Jerusalem artichoke (Helianthus tuberosus L.) – Gigant, Albik. Application of the fertilisers did not resulted in significant change in the total contents of phosphorus, potassium and magnesium in soil examined after Jerusalem artichoke was harvested. Application of ash from coniferous trees, with high levels of calcium, resulted in increased total contents of calcium in the soil. Fertilisation of the soil with ash from coniferous trees or with sewage sludge, as well as cultivation of two varieties of Jerusalem artichoke, resulted in a significant increase in the concentrations of cadmium and lead, and produced no effects in the levels of nickel, zinc and copper identified in soil. The above findings, and in particular the fact that the limit values were not exceeded, indicate the possibility of using both sludge and biomass ash for fertilizing Jerusalem artichoke.

Abstract:

Notable amounts of wood ash containing plant macro and micronutrient elements in balanced proportions are produced in Latvia. If bioenergy production source product is plant material, and facilities are operating well, then ‘side product’ fermentation residues or wood ashes should not contain elements in toxic concentrations. Wood ash contains P and K which are lacking in acidic organic soils and could work as fertiliser as well as a long term liming agent, besides that, all micronutrient elements necessary for physiological processes are present in wood ash. Wood ash could also be used as ‘revitalization agents’ – fertilisers to improve the growth of plantation forests. The aim of this research is to find and describe the positive effect of wood ash fertilisers on Norway spruce (Picea abies) and other economically valuable tree species. Research results show positive wood ash application effect on tree growth and vitality within the first 4 years when used for recultivation and revitalization purposes. Recycling of wood ash (0.5–3 t ha- 1 before planting) for fertilisation of and Picea abies forest plantations are a sustainable and effective solution for the improvement of tree growth as well as an environmentally safe method of utilization of bioenergy production residues.

Abstract:

In May 2011, a short rotation woody energy plantation (SRC) was established near Dejtár village in Northern–Hungary. The goal of the experiment was comparative analyses of different fertilization treatments on three clones of Populus (AF2, Monviso, Pannonia) and one Salix cultivar (‘Dékány’). We used three fertilization treatments: (1) 5 t ha–1 of wood ash, (2) 40 t ha–1 of farmyard manure and (3) both 5 t ha–1 of wood ash and 40 t ha–1 of farmyard manure. The Monviso clone had the highest survival rate (92%), followed by Pannonia (80%) and AF2 (78%). Initially, the white willow ‘Dékány’ cultivar was also included in the experiment, but due to differing site preferences of this cultivar, it was not viable in the area. Based on the data of the first three growing seasons, it was demonstrated that the important nutrients had already been present in optimal amounts from the start of the experiment, and their contents were increased due to the treatments. At the end of the first growing season, the effect of the fertilization treatment could not be detected, but by the third year the results showed a significant positive effect. Already in the second, but mostly at the end of the third growing season, the wood ash + manure fertilizer treated plots showed significant increases in height growth and biomass yield.

Abstract:

 Tall growing perennial grasses such as Phalaris arundinacea and Festulolium can be used as an alternative source for bioenergy production in northern latitudes as they can be grown in less cultivated areas and can be potentially used as a dual purpose crop (bioenergy and forage). The aim of studies was to investigate the effectiveness of using bioenergy waste products – fermentation residues (digestate) and wood ash as fertilisers for perennial grasses. The field experiment was conducted in the central part of Latvia (56°42′ N and 25°08′ E) from 2013 to 2015. For all fertiliser treatments (wood ash, digestate once per season; digestate twice per season and mineral fertilisers) the same amount of plant nutrients (N, P, K) was applied annually: N (100), P2O5 (80), K2O (160); and the missing quantities of elements in ash and digestate were compensated by mineral fertilisers. Dry matter yield (DMY) in two harvest regimes (single cut and two cut) and chemical composition (ash content; total C and N) of grass biomass partitioning among tillers, leaves and panicles were estimated.
Biomass yield in the three years of use varied considerably depending on the fertiliser, harvest regime and species, ranging up to 10.0 Mg ha-1 for RCG and 7.73 Mg ha-1 for festulolium. All fertilisers provided a significant increase of DMY, however, better results for both species were obtained using wood ash and mineral fertilisers. The harvest regime and species affected directly the quality of biomass, single cut of RCG contained significantly less ash and more carbon. There were significant differences between sward fractions – culms in comparison with leaves contained less ash and nitrogen, and more carbon, what are desirable features for solid fuel.

Abstract:

Due to the increasing of wood as energy renewable resource in power and heat plantsthe amount of wood ash as waste will increase. Wood ash contains plant macronutrientelements P, K and different elements as micronutrients, only organic and nitrogen are missing.Wastewater sludge from small municipalities is usually clean, first-class material and contains alot of nitrogen and phosphorus. Wood ash can be a good fertiliser and a liming material not onlyfor acid organic soils, but also for mineral soils, but with a less significant effect on the treegrowth in first seasons than a nitrogen rich fertiliser wastewater sludge.The effects that wood ash and wastewater sludge have on the increment and survival of treeswere tested during the years 2011 and 2012 on loam and loamy soils at plantations of blackalder, birch and grey alder, and they were compared with the results collected in the previousresearch started in 2005. It was observed that wood ash in the first two seasons did notsignificantly increase the growth of silver birch, as wastewater sludge did, but it had a positiveeffect on the annual increment of grey alder. Fertilisation of the whole field decreased thesurvival of trees because of weed competition and different injuries.The aim of the study was to evaluate the growth of fast-growing deciduous trees seedlings asshort rotation crop under fertilisation of wood ash, and wastewater sludge on former agriculturalland.
