“…(2)]. For the calculation of the N amount remaining in crop residues, data from our field experiment were used for calculation of the N amount remaining on field as above-ground harvest residues (stubble, leaves), assuming that 10% of silage maize harvested remained in the field (Jacobs et al, 2017). For calculation of the N amount from belowground harvest residues the IPCC (2006) default values for maize (Equation 11.7a; Tab.…”

“…Thus, annual data sets are a prerequisite for a reliable assessment of practical measures to reduce direct N 2 O emission from agricultural soils (Webb et al, 2010). Based on calculated data, it was shown for different cropping systems that N 2 O emissions from soils are the largest contributor to total GHG emission on field level (Camargo et al, 2013;Jacobs et al, 2017). However, the authors criticized the high uncertainty and the missing adaption of site-specific N 2 O emission factors (EF).…”

“…However, the authors criticized the high uncertainty and the missing adaption of site-specific N 2 O emission factors (EF). Consequently, Camargo et al (2013) and Jacobs et al (2017) arrogated additional research on quantifying N 2 O emission from crop production with field measurements. Pucker et al (2013) used an application technique-specific N 2 O EF for the calculation of field-related N 2 O emissions after digestate fertilization according to Wulf et al (2002bWulf et al ( , 2006.…”

We determined N2O fluxes from an unfertilized control (CON), from a treatment with mineral N‐fertilizer (MIN), from cattle slurry with banded surface application and subsequent incorporation (INC), and from slurry injection (INJ) to silage maize (Zea mays, L.) on a Haplic Luvisol in southwest Germany. In both years, amount of available N (total N fertilized + Nmin content before N application) was 210 kg N ha−1. In the slurry treatment of the 1st year, 140 kg N ha−1 were either injected or incorporated, whereas 30 kg N ha−1 were surface applied to avoid destruction of the maize plants. In the 2nd year, all fertilizers were applied with one single application. We calculated greenhouse gas emissions (GHG) on field level including direct N2O emissions (calculated from the measured flux rates), indirect N2O emissions (NH3 and NO3 - induced N2O emission), net CH4 fluxes, fuel consumption and pre‐chain emissions from mineral fertilizer. NH3 losses were measured in the 2nd year using the Dräger‐Tube Method and estimated for both years. NH3 emission was highest in the treatment without incorporation. It generally contributed less than 5% of the greenhouse gas (GHG) emission from silage maize cultivation. The mean area‐related N2O emission, determined with the closed chamber method was 2.8, 4.7, 4.4 and 13.8 kg N2O‐N ha−1 y−1 for CON, MIN, INC, and INJ, respectively. Yield‐related N2O emission showed the same trend. Across all treatments, direct N2O emission was the major contributor to GHG with an average of 79%. Trail hose application with immediate incorporation was found to be the optimum management practice for livestock farmers in our study region.

“…Although AD is not a new technology, it has changed enormously in recent years. Although the following quotation from Grandoa et al () appears questionable based on, for example, Jacobs et al () or Auburger et al, (), it shows the sustainable potential of biogas production: “Anaerobic digestion technology for biogas production constitutes today the most sustainable way of using the energy present in biomass and other wastes, because it also increases nutrient recovery and reduces greenhouse gas emissions.” One of these major advances is the flexible, demand‐oriented production, and use of biogas. When decentralized, this can make a significant contribution to stabilizing the electricity grids, which will be burdened by the fluctuating electricity production of photovoltaics and wind power plants and their rapid expansion (Lemmer & Krümpel, ).…”

Biogas is in many respects a serious alternative to other fossil resources and complements other renewable energy sources from wind and sun. Biogas can be produced in many places decentrally. Its energy potential is high, and it is widely used in the EU and all over the world. With more than 16,000 ktoe of oil equivalent in the EU in 2016, it corresponds to approximately 8% of the total primary energy produced by renewable energies in the EU, produced with nearly 17,000 biogas plants. Nevertheless, the production costs of biogas and its products like energy, heat, and fuel are still too high. Kost et al. (2018) show a comparison of electricity generation costs of different renewable energies and their future potentials. While electricity from huge biogas plants offers generation costs from 10 to 15 ct/kWh, electricity from onshore wind and huge solar systems offers generation costs from 4 to 8 ct/kWh. Although substantial progress has been made with regard to substrate use, production techniques and market designs, many more innovations are needed throughout the biogas value chain for it to be competitive in energy markets without high subsidies. As several papers in the special issue on biogas show, there are numerous innovations and product designs with regard to energy and material uses that could maintain or even increase the importance of biogas production both within and outside of the EU. There are many potential benefits of biogas, as it offers high shares of produced renewable energies as well as large amounts of material products like digestates and in future maybe products of higher value such as proteins or lactic acids.
