“…The latter clearly suggests that environmental factors specifically soil moisture was the most dominant factor in 2014 that leads to relatively high N 2 O fluxes and without sufficient moisture or rainfall, fertilizer application alone does not affect N 2 O fluxes significantly, e.g., in 2015. In line with the present study, authors also reported that the application of organic or inorganic fertilizers affects N 2 O fluxes only in wet seasons but not in dry years [10,17,19]. Overall, the application of nitrogenous fertilizer affected N 2 O fluxes predominantly in cropland soils and had limited impact in agro-forestry soils.…”

“…Our earlier report supports this hypothesis in which sandy loam soil was incubated under laboratory conditions, and similar to the field experiment, large N 2 O peak events were observed immediately after rewetting of the soil. Here, a stable isotope-labeling study clearly showed that denitrification was the major source (over 90 % of emitted N 2 O) of large N 2 O peaks that occurred in wet seasons [8,19]. Furthermore, there is now a growing evidence that fungal denitrification may be the key process producing N 2 O in such situations rather than bacterial denitrification [17].…”

“…The relevance of soil moisture can also be seen in field studies with similar climatic, soil, and substrate conditions, where N 2 O emissions nevertheless show significant inter-annual variability caused by the differences in soil water content [19]. These differences can usually be deduced from the weather records as they are related to the differences in the input of water through rainfall [18].…”

“…Crop plants play an important role, as they may transpire 500 to 600 mm of water per growth cycle which is 30 to 90 % of the precipitation input in that period. In this respect, crops differ substantially, not only in the total amount of water that is transpired but also in the growth and transpiration pattern in the course of the year [19,20].…”

Legume-based mixed intercropping systems may lower agricultural born N2O emissions

Background: The area used for bioenergy crops (annual row crops (e.g., wheat, maize), herbaceous perennial grasses, and short-rotation woody crops (e.g., poplar)) is increasing because the substitution of fossil fuels by bioenergy is promoted as an option to reduce greenhouse gas (GHG) emissions. However, biomass used for bioenergy production is not per se environmentally benign, since bioenergy crop production is associated with negative side effects such as GHG emissions from soil (dominated by N 2 O). N 2 O emissions vary greatly in space and time; thus, direct comparison of soil N 2 O fluxes from various agro-ecosystems is certainly crucial for the assessment of the GHG reduction potential from energy crops.

“…In general, clayey soils exhibit a lower gas diffusivity compared to coarse-textured soils. This regularly results in higher denitrification in the former with higher N 2 O emission rates, but also a higher probability for the consecutive reduction to N 2 (Ball, 2013;Gu et al, 2013;Senbayram et al, 2014).…”

Abstract. Biogas digestate (BD) is increasingly used as organic fertilizer, but has a high potential for NH 3 losses. Its proposed injection into soils as a countermeasure has been suggested to promote the generation of N 2 O, leading to a potential trade-off. Furthermore, the effect of high nutrient concentrations on N 2 losses as they may appear after injection of BD into soil has not yet been evaluated. Hence, we performed an incubation experiment with soil cores in a helium-oxygen atmosphere to examine the influence of soil substrate (loamy sand, clayey silt), water-filled pore space (WFPS; 35, 55, 75 %) and application rate (0, 17.6 and 35.2 mL BD per soil core, 250 cm 3 ) on the emission of N 2 O, N 2 and CO 2 after the usage of high loads of BD. To determine the potential capacity for gaseous losses, we applied anaerobic conditions by purging with helium for the last 24 h of incubation. Immediate N 2 O and N 2 emissions as well as the N 2 / (N 2 O+N 2 ) product ratio depended on soil type and increased with WFPS, indicating a crucial role of soil gas diffusivity for the formation and emission of nitrogenous gases in agricultural soils. However, emissions did not increase with the application rate of BD. This is probably due to an inhibitory effect of the high NH + 4 content of BD on nitrification. Our results suggest a larger potential for N 2 O formation immediately following BD injection in the fine-textured clayey silt compared to the coarse loamy sand. By contrast, the loamy sand showed a higher potential for N 2 production under anaerobic conditions. Our results suggest that short-term N losses of N 2 O and N 2 after injection may be higher than probable losses of NH 3 following surface application of BD.

High‐energy demand with rapid industrialization and mechanization combined with environmental pollution due to the burning of fossil fuels has driven a shift toward renewable energy. Biogas derived from biomass is a potential renewable energy source that can be used in different sectors such as transportation sector, electricity generation, heat production, combined heat and power (CHP) systems, and fuel cells. Moreover, the upgraded biogas can be applied as transportation fuel via an internal combustion chamber (for internal combustion engine (ICE) vehicles), and electricity station (for electric vehicles). In the present work, a conceptual review of biogas‐based electrical power production systems is presented. It is clear that the conventional types of biomass contain a high amount of pollutants and unwanted constituents, which lower the lower heating value (LHV) of biogas fuel. Moreover, the energy and exergy efficiencies of biogas applications are influenced by these components. Consequently, several biogas‐upgrading technologies have been elaborated to increase the LHV of biogas fuel by removing biogas pollutants. So, the energy and exergy analyses of biogas‐driven plants are discussed in this regard. Also, the economic analysis of biogas‐fueled systems is measured through the connection between biogas production, purchased electrical power, and selling of an additional amount of biogas. Biogas represents an important source of renewable energy as shown before, and it helps in waste management and W‐to‐E (waste to energy) conversion, which allows utilizing huge amounts of wastes instead of disposal or landfill procedures. However, handling of biogas from production to utilization has an impact on the environment. Therefore, the assessment of the environmental impacts of biogas plants is presented. In addition, a combination of the biogas energy with other sources, especially renewable energy sources (eg, solar‐biogas, geothermal‐biogas, wind‐biogas, CHP, CCHP, and concentrated photovoltaic‐biogas), and reusing waste energy for other tasks (eg, employing the waste heat from a gas turbine) are examined.
