“…The soil C inputs were much lower for the digestates from concentrates than from digestates from feedstocks rich in fibers (Fouda et al 2013). The high degradability of digestates from clover-grass was confirmed by findings reported by Johansen et al (2013).…”

“…The feedstocks used for anaerobic digestion and the degradability of the remaining organic matter in the digestates influence the N 2 O emissions after field application (Johansen et al 2013). Consequently, digestates with a high degradability of the organic matter such as grass-clover caused a significantly stronger increase of the N 2 O emissions than, e.g., digestates derived from maize digestion with a lower shortterm biodegradability.…”

“…In cropped fields, very often, no or minor differences in soil biological activity were measured in comparison to application of undigested feedstocks (Allan et al 2003;Schauss et al 2006;TerhoevenUrselmans et al 2009;Clements et al 2012;Walsh et al 2012b;Bachmann et al 2014), whereas in an experimental setup carried out on fallow land, the differences between undigested and digested manures were very often significant (Friedel et al 1996;Ernst et al 2008;Terhoeven-Urselmans et al 2009). Simultaneously, the influence of anaerobic digestion on soil microbial activity is also mediated by the used feedstock (Johansen et al 2013). Digestates with a high degradability of the organic matter such as clover-grass have a stronger effect on the short-term soil microbial activity than digestates with a low degradability such as silage maize.…”

“…It was often hypothesized that on a long-term, soil organic matter content will decrease and the soil biological activity may be hampered when a systematic removal of carbon fixed in manure and crop residues for energy purposes are implemented, leading to decreased quantities of organic materials with less easily available C applied to soils after implementation of a biogas plant (Lampkin 1990;Heilmann 1992;Haas 2000;Scheller 2006). Therefore, especially organic farmers are concerned that fertilization with the digestates may impact the soil microbiota and soil fertility because they contain more mineral nitrogen and less organic matter than the non-digested input materials (e.g., untreated animal slurry, plant residues, or green manure biomass) (Johansen et al 2013). Simultaneously, anaerobic digestion leads to an increase of manure pH and also to transformation of nitrogen (N) compounds (e.g., EIShinnawi et al 1989;Möller and Müller 2012).…”

Sustainability in agriculture means the inclusion of several aspects, as sustainable agriculture systems must not compromise not only their ability to satisfy future needs by undermining soil fertility and the natural resource base but also sustainable agriculture has had to address a range of other issues including energy use, efficient use, and recycling of nutrients, the effects on adjacent ecosystems including the effects on water bodies and climate change. Organic manures are an important factor to keep the soil fertility level of soils. However, their management is often related to large emissions. In this context, anaerobic digestion is-similarly to composting-a treatment option for stabilization of biogenic wastes leading to a residual product called digestates, enabling the sanitation and the recycling and use as fertilizer. It is also a means to obtain energy from wastes as well as from dedicated energy crops. Therefore, anaerobic digestion potentially addresses several aspects of agricultural sustainability. This review discusses the current state of knowledge on the effects of anaerobic digestion on organic compounds in digestates and the most important processes influencing N emissions in the field, as well as the possible longterm effects on soil microbial biomass and soil fertility. The main findings are that (1) the direct effects of anaerobic digestion on long-term sustainability in terms of soil fertility and environmental impact at the field level are of minor relevance. (2) The most relevant effects of anaerobic digestion on soil fertility as well as on N emissions will be expected from indirect effects related to cropping system changes such as changes in crop rotation, crop acreage, cover cropping, and total amounts of organic manures including digestates. Furthermore, (3) the remaining organic fraction after anaerobic digestion is much more recalcitrant than the input feedstocks leading to a stabilization of the organic matter and a lower organic matter degradation rate after field application, enabling a similar reproduction of the soil organic matter as obtained by direct application of the feedstock or by composting of the feedstock. (4) Regarding emissions, the main direct effect of anaerobic digestion on a farm level is the influence on gaseous emissions during manure or digestate treatment and handling, whereas the direct effects of anaerobic digestion on a field level on emissions (NH 3 − and N 2 O − emissions, NO 3 -leaching) are negligible or at least ambiguous. (5) The main direct effects of anaerobic digestion on the field level are short-term effects on soil microbial activity and changes in the soil microbial community. Therefore, in terms of the effects on agricultural sustainability, potential cropping system-based changes induced by introduction of biogas plants are probably much more relevant for the overall performance and sustainability of the cropping system than the direct effects triggered by application of digestates in comparison to the undigested feedstock...

“…BD also increases the content of organic C in the soil and reduces the rate of its transformation in comparison to non-digested input organic materials (Chen et al 2012, Johansen et al 2013, Lopedota et al 2013. BD contains more (60-70% of total N) mineral nitrogen (NH4 + / NH3 -) compared to different types of organic fertilizers (e.g., compost, cattle manure contains 6-30% mineral N of total N) (Svensson et al 2004, Alburquerque et al 2012, Lopedota et al 2013.…”

Non-standard materials used for plant fertilization, require characterization to reduce any possible undesired effects. The aim of this study was to investigate the effect of fertilization with biogas digestate (BD) and mining waste (carboniferous mudstones (MS) from coal mine) on wheat yield quality and the bioaccumulation of heavy metals in wheat grains in relation to conventional fertilization (NPK) and no fertilization. Using the co-application of waste (MS+BD), the highest yield was obtained in the first and second year, but in the third year, a slight decrease in yield was observed compared to NPK. In all years, BD and MS+BD fertilization increased the content of protein, wet gluten, and phenols in wheat grain compared to NPK and no fertilization. Waste fertilization had a positive effect on the antioxidant capacity index of grain but only in the first year. The bioaccumulation index (BAI) demonstrated that NPK decreased BAI for Zn, B, Cd, and Mn, whereas MS+BD decreased BAI for Cu, Sr, Pb, Co, Ba, and Cr.
