In this eight-year grassland field trial, we compared the fertilization effects of biomass ashes (BMAs) and carbonated lime (CaCO3) in combined application with cattle slurry (CS). Our study focused on plant coverage, forage yield, and quality, as well as soil physicochemical and microbiological properties. The fertilization strategies included CS...
Urban drainage systems have developed way beyond the traditional piped combined or separate sewer systems. Many ‘new’ systems are being introduced, ranging from stormwater infiltration facilities to green roofs. However, the widely advocated blue-green infrastructures are typically overlooked by asset managers, which will very likely have detriment...
A globally increased demand for fuels and environmental concerns regarding fossil sources call for sustainable alternatives. Fast pyrolysis is a promising approach for converting different types of biomass to renewable Fast Pyrolysis Bio-Oil (FPBO) that can be used for heating, power generation and mobility. Side-products emerging from the process...
In recent years, there has been a veritable boost in next-generation sequencing (NGS) of gene amplicons in biological and medical studies. Huge amounts of data are produced and need to be analyzed adequately. Various online and offline analysis tools are available; however, most of them require extensive expertise in computer science or bioinformat...
Because of its nutritious properties, the black soldier fly has emerged as one of the most popular species in advancing circular economy through the re-valorization of anthropogenic organic wastes to insect biomass. Black soldier fly frass accumulates as a major by-product in artificial rearing setups and harbors great potential to complement or re...
Fast pyrolysis bio-oil (FPBO) is a liquid biofuel obtained from lignocellulosic residues. Moreover, biomass fly ashes (FAs) containing many minerals and micronutrients are obtained in the production process. Biomass ashes can be used as a lime substitute for amelioration of acid soils by increasing pH, providing nutrients for crop development and s...
A study on locally available composts in Austria, Germany, Italy and Switzerland was conducted to investigate the potential of these non-chemical based tools to increase soil health in orchards afflicted by apple replant disease (ARD). A total of 26 different composts (six to seven per country) were chosen for the study. Composts were divided into...
Essential oils (EO) of several plant species have the potential to combat plant and fungal diseases. However, the effects of Achillea millefolium EO on the development of common bean (Phaseolus vulgaris L.), is still unknown. Moreover, its effect on N2-fixing bacteria, and in general on soil properties has not been studied yet. A greenhouse trial w...
The production of fast pyrolysis bio oil (FPBO) constitutes one of the newest technologies for gaining a liquid biofuel from woody biomass. During this process biomass fly ashes (FAs), rich in minerals and salts, are produced. However, FAs are often disposed in landfills and their fertilising potential has been underestimated. A greenhouse trial wa...
The aim of the study was to investigate the option to purify biogas from small-scale biogas plants by entrapping CO2 and H2S with regionally available biomass ash. Connected to the existing biogas plant Neustift (Tyrol) wood ash placed in a 1 m(3) container was used as a trap for CO2 and H2S in the biogas. With the process conditions chosen, for a...
What happens when an old soil amendment is in fact a new one? Traditionally, ashes from biomass combustion were considered as a valuable resource, and widely used as an agricultural soil amendment. However, in recent decades we have been reluctant to apply them to soils, despite the increase in the production of combustion ashes resulting from the...
Despite the widespread use of sewage sludge as an organic amendment to improve soil stability and plant productivity, relatively little is known about how the different sludge stabilization processes affect the microbial composition and diversity of the sludge and the soil microbial populations as well as plant performance. In this study, the effec...
Background:
Cellulose-containing waste products from the agricultural or industrial sector are potentially one of the largest sources of renewable energy on earth. In this study, the biomethane potential (BMP) of two types of industrial paper wastes, wood and pulp residues (WR and PR, respectively), were evaluated under both mesophilic and thermop...
Fermentation residues frombiogas production are known as valuable organic fertilisers. This study deals with the effect of cattle slurry, co-digested cattle slurry, co-digested energy crops and mineral fertilisers on the activity and composition of soil microbiota. Furthermore, the effect of solid–liquid separation as a common pre-treatment of dige...
The application of wood ash to forest soils has been used to compensate nutrient loss and avoid soil and water acidification. Using ashes in a non-stabilized form might negatively affect forest ecosystems. Bearing this in mind, together with landscape restrictions and socio-economic parameters, it underlines the importance of using pelletized ashes...
A trial at semi-industrial scale was conducted to evaluate the effect of wood ash amendment on communal biowaste in a composting process and on the final composts produced. For this purpose, three treatments including an unamended control (C0) and composts with additions of 6% (C6), and 12% (C12) of wood ash (w/w) were studied, and physico-chemical...
Conference paper - abstract: with biomass ahses it is possible to clean biogas (H2S and CO2 removal)
SARDINIA 2015 – 15th International Waste Management and Landfill Symposium, S. Margherita di Pula, 05.-09.10.2015
Anaerobic digestion has become increasingly popular as an alternative for recycling wastes from different origins. Consequently, biogas residues, most of them with unknown chemical and biological composition, accrue in large quantities and their application into soil has become a widespread agricultural practise. The aim of this study was to evalua...
Since the 1950s the whole-tree harvesting has led to the removal of high-valuable nutrients such
as calcium, potassium, magnesium and phosphorus from the forest life cycle. The current tendency
to use biomass as a sustainable and regional energy source results in an increased production
of high quality wood ash, which could play a key role in compe...
Anlass dieses Artikels ist das 50. Erscheinungsjubiläum von Rachel Carsons Buch " Der stumme Frühling " , in welchem die Entwicklung des Pestizideinsatzes kritisiert wird. Dabei betrachten wir Rachel Carsons Metapher eines stummen Frühlings, verursacht vom Verschwinden der Vögel, im Bezug zum Umgang mit Pestiziden. Nach einer kurzen Einleitung zum...
A field study was carried out to evaluate the potential of wood ash as a fertilizer in grassland systems in combination with enriched N organic wastes. Six treatments including manure or digestate, each combined with wood ash at 0, 1, and 3 t ha−1 were spread onto the soil to an amount equivalent to 120 kg N ha−1. Three soil samplings and one cutti...
Currently, the amount of wood combusted in heat and power plants and thus the production of wood ash are steadily increasing. To a large extent, the wood ash is deposited in waste dumps despite its potential as a fertilizer or fertilizer supplement, interrupting the nutrient cycle.
The aim of the study is to pave the way for a meaningful recycling...
This work compilates the infiltration rates that were obtained in a Calcisol which was under four different soil management. It was a split-plot design with 4 main-plot treatments: Fencing, Cover crop, Native Vegetation and Traditional tillage; and six subplots, three of them, were grazed in spring, the other 3 were not. The infiltration rates, tha...
