“…The BAU and MWD showed similar levels of emissions, 312 PMD had relatively lower emissions but SID showed a peculiar, and quite contrasting emission trend, 313 with increasing levels of emissions recorded about two weeks post land application (Fig. 5), which is also 314 reported in previous studies (Möller and Stinner, 2009;Nyord et al, 2008). The background N 2 O 315 emissions from the bare soil have also been shown in this figure for reference.…”

“…From an environmental point of view there is an existing 59 challenge of reducing the gaseous N-losses (NH 3 , NO 2 , N 2 O) from digestate soil application to the fields 60 (Balsari et al, 2007;Misselbrook et al, 2005a;Nyord et al, 2008;Tiwary et al, 2015). This study aims 61 to determine and interpret the seasonal emissions profile to air from digestate slurry applied to urban soil.…”

“…It evaluates the implications for climate change and urban pollution in 64 terms of fitness for purpose of the available practice, including some proposed mitigation strategies. Several studies have reported monitoring of NH 3 emissions from land-applied manure in Europe (Gericke 78 et al, 2011;Loubet et al, 1999;Misselbrook et al, 2005a;Nyord et al, 2012;Nyord et al, 2008), 79…”

Highlights:· In situ air pollution assessment of land applied digestate is performed. · Environmental burden minimisation scenarios for digestate bio fertiliser presented. · Food-based digestate show high ammonia volatilisation potential. · Soil incorporated digestate effectively reduces NH 3 but elevates N 2 O emissions. · Managing digestate emissions mitigate both climate change and air pollution. Abstract (limit 150 words only)Anaerobic digestion (AD) of putrescible urban waste for energy recovery has seen rapid growth over recent years. In order to ascertain its systems scale sustainability, however, determination of the environmental fate of the large volume of digestate generated during the process is indispensable. This paper evaluates the environmental burdens to air associated with land applied food-based digestate in terms of primary pollutants (ammonia, nitrogen dioxide) and greenhouse gases (methane and nitrous oxide). The assessments have been made in two stages -first, the emissions from surface application of food-based digestate are quantified for the business as usual (BAU). In the next step, environmental burden minimisation potentials for the following three mitigation measures are estimated -mixed waste digestate (MWD), soil-incorporated digestate (SID), and post-methanated digestate (PMD). Overall, the mitigation scenarios demonstrated considerable NH 3 , CH 4 and N 2 O burden minimisation potentials, with positive implications for both climate change and urban pollution.

“…Similar results were reported also by Boelcke (2000). Nyord et al (2008b) explains lower yields of winter wheat fertilized with nitrogen injection as a result of too tough soil in his experiment; point injector thus was not able to penetrate it and inject all the fertilizer to the required depth, certain amount of fertilizer then rested on the soil surface where it volatilized. They further suggest the minimum depth for effective usage of the fertilizer as 5 cm.…”

The CULTAN (Controlled Uptake Long Term Ammonium Nutrition) system is based on one-time injection of the whole dose of nitrogen required for the vegetation period. The effect of this method on yield and grain quality of winter wheat was observed in a 2-year small-plot trial at 4 different experimental sites in the Czech Republic. The experiment comprised two treatments with the total amount of nitrogen applied during fertilization of 150 kg N/ha. At the CULTAN treatment the whole dose was applied all at once using the GFI 3A injection machine (Maschinen und Antriebstechnik GmbH Güstrow), whereas at the control treatment, the dose was divided into three applications. The average grain yield of winter wheat in 2007 was 9.56 t/ha (control) and 8.78 t/ha (CULTAN); in 2008 it was 9.91 t/ha (control) and 9.63 t/ha (CULTAN). The differences in 2008 were not statistically significant. The contents of nitrogen and gluten were significantly lower at CULTAN treatment in both years. The values of falling number, Zeleny test and bulk density were generally similar at both treatments.

“…If liquid organic fertilizers are applied to the soil surface using band spreaders or broadcast spreaders, then 20-40% of the total ammoniacal N can be lost (Nyord et al 2008). Injection reduces NH 3 losses up to 2% of total ammoniacal N (Huijsmans et al 2003).…”

In conjunction with soil type and climate, the use of nitrogen fertilizers is a major factor affecting nitrous oxide emissions. This study compares injection of pig slurry and pig slurry digestate at 15 or 20 cm depths with trailinghose application followed by immediate incorporation. The work was based on a laboratory microcosm experiment with undisturbed soil cylinders (0-30 cm depth) from three arable soils (Histosol, Gleysol and Plaggic Anthrosol). Soil cylinders were fertilized with pig slurry and pig slurry digestate (150 kg N/ha) and emissions of N 2 O, CH 4 and CO 2 were monitored. The comparison of application techniques over a 37-day period show that soil type and application technique, had a strong (P < 0.001) impact on N 2 O emissions. Fertilization with pig slurry showed no significantly higher N 2 O emissions than pig slurry digestate. Fertilizer injection significantly increased N 2 O emissions compared to fertilization with a trailing-hose with incorporation.
