“…However, the emissions observed at our sites were gross fluxes influenced by historical N inputs and residue management and therefore not only attributable to the most recent N additions. Within agricultural systems, there can be substantial background N 2 O emissions as demonstrated when N-application is omitted (Kavdir et al, 2008;Petersen et al, 2006).…”

“…Many previous inventories or measurement studies on N 2 O flux dynamics have focused on ecosystems or landuse types such as forests Kesik et al, 2005), wetland/organic soils (Maljanen et al, 2003), grasslands (Flechard et al, 2007;, or arable crop rotations in experimental plots (Petersen et al, 2006;Chirinda et al, 2010). However, there have been few attempts (Dunmola et al, 2010) to cover the mosaic of land use types encountered at the landscape scale within a single study.…”

Abstract. Nitrous oxide (N 2 O) emissions from agricultural land are variable at the landscape scale due to variability in land use, management, soil type, and topography. A field experiment was carried out in a typical mixed farming landscape in Denmark, to investigate the main drivers of variations in N 2 O emissions, measured using static chambers. Measurements were made over a period of 20 months, and sampling was intensified during two weeks in spring 2009 when chambers were installed at ten locations or fields to cover different crops and topography and slurry was applied to three of the fields. N 2 O emissions during spring 2009 were relatively low, with maximum values below 20 ng N m −2 s −1 . This applied to all land use types including winter grain crops, grasslands, meadows, and wetlands. Slurry application to wheat fields resulted in short-lived two-fold increases in emissions. The moderate N 2 O fluxes and their moderate response to slurry application were attributed to dry soil conditions due to the absence of rain during the four previous weeks. Cumulative annual emissions from two arable fields that were both fertilized with mineral fertilizer and manure were large (17 kg N 2 O-N ha −1 yr −1 and 5.5 kg N 2 O-N ha −1 yr −1 ) during the previous year when soil water conditions were favourable for N 2 O production during the first month following fertilizer application. Our findings confirm the importance of weather conditions as well as nitrogen management on N 2 O fluxes.

“…Although GHG emissions of organic farming systems have been investigated in Europe and North America (Flessa et al 2002;Kramer et al 2006;Petersen et al 2006;Syvä salo et al 2006), GHG emission has not yet been investigated in Japanese organic farming systems, as far as we know. Andosol, which generally contains much higher concentrations of soil organic carbon, covers >50% of the total upland arable area in Japan (Oda et al 1987;Shoji et al 1993).…”

Here we have investigated the emission of carbon dioxide (CO 2 ), methane (CH 4 ), and nitrous oxide (N 2 O) from long-and short-term organic farming Andosols in Matsumoto city of Nagano, in central Japan. We focus on three upland plots in Matsumoto, distinguished by how long they had each experienced continuous organic farming ( , respectively. Greenhouse gas (GHG) balance was calculated at -52 and 97 g CO 2 -C equivalent m -2 in M39-OF and M1F-OF, respectively. Negative GHG balance indicated that M39-OF was acting as a GHG sink, with higher CH 4 absorption than M1F-OF. Further, this beneficial function for global warming was thought to be based on its cultivation system, which had included green manure application since 2001. The difference in gas exchange between incubation and field experiments was considered a reason for the difference in N 2 O emission between incubation and field experiments.

“…The emission of ammonia levels reached also contributes to the protection of the atmosphere in the small farming (Haas et al, 2001, Geier et al, 1998. Emissions of greenhouse gases range is moderate, as it has been demonstrated in several national research (Petersen et al, 2005;Robertson et al, 2000;Hörtenhuber et al, 2010). …”
