“…In 2010 and 2011, the separated solids and cattle manure were surface applied and incorporated with an offset disc (about 2 to 10 cm depth). The incorporation methods were selected as representative of best management practices aimed at minimizing N losses (Webb et al, 2013; Cambareri et al, 2017). Nevertheless, differences in how the separated solids and cattle manure were applied compared with the digestate likely contributed to the year‐to‐year variability observed for these treatments.…”

“…G lobally , there is limited information about how biogas residues influence nitrous oxide (N 2 O) emissions after they are applied to soil (Charles et al, 2017) and even less information for rainfed semiarid areas (Meijide et al, 2009; Aguilera et al, 2013). In Canada, most research on N 2 O emissions from agricultural soils amended with biogas residues has been conducted in eastern Canada (Chantigny et al, 2007; Schwager et al, 2016; Cambareri et al, 2017). Little or no data are available for the much drier semiarid climates of western Canada.…”

Limited information is available about soil nitrous oxide (N 2 O) fluxes, N 2 O emission factors (EFs), and yield-scaled N 2 O emissions for biogas residues used to fertilize crops in semiarid regions. To address this knowledge gap, a 4-yr field experiment was conducted in a semiarid climate to determine growing season N 2 O fluxes from soil receiving (i) anaerobically digested solid beef cattle manure (digestate), (ii) separated solids from the digestate (separated solids), and (iii) undigested solid beef cattle manure (cattle manure) applied to target one and two times the recommended rates (200 and 400 kg total N ha -1 ) for barley (Hordeum vulgare L.) forage, assuming 50% of N was annually plant available. Nitrous oxide fluxes were determined using vented static chambers. Over the four growing seasons, 95, 80, and 81% of the N 2 O flux occurred within 36 d of applying digestate, separated solids, and cattle manure, respectively. The cumulative N 2 O emissions with digestate were 4.7 and 4.1 times the values of the separated solids and cattle manure, respectively. The digestate N 2 O EF was 13.6 and 10.6 times the values of the separated solids and cattle manure, respectively, but the N 2 O EF based on applied mineral N was similar for all amendments. The yield-scaled N 2 O emissions with digestate were 4.3 and 3.6 times the values of the separated solids and cattle manure, respectively. In the semiarid region of southern Alberta, liquid biogas residues have a higher risk for N 2 O emissions than both the separated solid fraction of the biogas residues and undigested cattle manure.

“…Gas samples were collected using static enclosed chambers. The sampling chamber consisted of two units (a collar and lid): (a) the collar, a polyvinyl chloride (PVC) open cylinder (inner diameter = 44.2 cm, outer diameter = 45.7 cm, and height = 19 cm) which was inserted between corn rows to a depth of 10 cm at each sampling location; (b) a PVC lid with 8.3 cm height, covered with round PVC sheet (1.27 cm thick) fixed into positions using PVC cement [60]. The lids were covered with insulating double-layered reflective bubble wrap.…”

“…The Chamber lid had tubing outlets connected to an internal four-port manifold, made of polypropylene union tees and four tubes (15 cm long by 0.15 cm internal diameter) (Chemfluor FEP, Cole-Parmer) to collect the samples from four points within the headspace ensuring a representative sample. A 10 cm long and 0.48 cm inner diameter vent tube was connected to the lid to compensate for inner and outer air pressure [60]. For each measurement, four gas samples were taken from the chamber using a 20 mL non-sterile syringe at 10 min intervals (0, 10, 20, and 30 min after closure) [61].…”

Topography Controls N2O Emissions Differently during Early and Late Corn Growing Season

et al. 2021

Topography affects soil hydrological, pedological, and biochemical processes and may influence nitrous oxide (N2O) emissions into the atmosphere. While N2O emissions from agricultural fields are mainly measured at plot scale and on flat topography, intrafield topographical and crop growth variability alter soil processes and might impact N2O emissions. The objective of this study was to examine the impact of topographical variations on crop growth period dependent soil N2O emissions at the field scale. A field experiment was conducted at two agricultural farms (Baggs farm; BF and Research North; RN) with undulating topography. Dominant slope positions (upper, middle, lower and toeslope) were identified based on elevation difference. Soil and gas samples were collected from four replicated locations within each slope position over the whole corn growing season (May–October 2019) to measure soil physio-chemical properties and N2O emissions. The N2O emissions at BF ranged from −0.27 ± 0.42 to 255 ± 105 g ha−1 d−1. Higher cumulative emissions were observed from the upper slope (1040 ± 487 g ha−1) during early growing season and from the toeslope (371 ± 157 g ha−1) during the late growing season with limited variations during the mid growing season. Similarly, at RN farm, (emissions ranged from −0.50 ± 0.83 to 70 ± 15 g ha−1 d−1), the upper slope had higher cumulative emissions during early (576 ± 132 g ha−1) and mid (271 ± 51 g ha−1) growing season, whereas no impact of slope positions was observed during late growing season. Topography controlled soil and environmental properties differently at different crop growth periods; thus, intrafield variability must be considered in estimating N2O emissions and emission factor calculation from agricultural fields. However, due to large spatial variations in N2O emissions, further explorations into site-specific analysis of individual soil properties and their impact on N2O emissions using multiyear data might help to understand and identify hotspots of N2O emissions.

“…The project took place at a commercial dairy farm before and after the installation of a biogas system, from 2010 to 2015. Greenhouse gas emissions from the main dairy barn were reported in Ngwabie, Vanderzaag, Jayasundara, and Wagner‐Riddle (2014), and those associated with dairy manure–digestate applications to soils are described in Cambareri, Drury, Lauzon, Salas, and Wagner‐Riddle (2017) and Cambareri, Wagner‐Riddle, Drury, Lauzon, & Salas (2017). Emissions of CH 4 from untreated dairy manure storage during August 2010 to November 2011 were reported in Kariyapperuma et al.…”

Increased dairy farm methane concentrations linked to anaerobic digester in a five‐year study

Organic waste materials are sources of anthropogenic methane (CH4) emissions. Anaerobic digestion (AD) is a technology that produces biogas from organic waste materials, and CH4 is the primary component of biogas. Unintended emission of CH4 from biogas facilities could undercut the environmental benefits of this technology. The objective of this study was to determine if the implementation of an AD system affected ambient CH4 concentrations ([CH4]) on a commercial dairy farm over 5 yr, from before installation into full operation. Concentrations at 4.5‐m height on a tower receiving wind that originated from various directions, comprising components of the dairy farm such as the AD facility, crop fields, or main barn, were measured using a closed‐path tunable diode laser trace‐gas analyzer. In 2012 and 2013, the first 2 yr of AD operation, [CH4] was not significantly different than pre‐AD levels in 2011 (2.04 ± 0.01 μl L−1). However, mean [CH4] increased to 2.47 ± 0.03 and 2.48 ± 0.04 μl L−1 in 2014 and 2015, respectively, and the occurrence of high [CH4] (>10 μl L−1) increased from <0.05% in Year 1 (pre‐AD) to 12% in Years 4 and 5. These elevated concentrations were related to an increased use of food waste feedstocks over time and suggest that the biogas system was a source of fugitive CH4 emissions. Food waste materials have a high biogas potential and are a valuable resource that require appropriate facility design and management to fully harness their benefits.
