“…On the other hand, there are some studies which report N 2 O emissions of the same magnitude or even higher than those of the present study, e.g. Rizhiya et al ( 2011 ) for wild cabbage leaves (C:N = 21, EFR 25 mg N 2 O-N/g residue-N in 50 days), Velthof et al ( 2002 ) for white cabbage (C:N = 21), Brussels sprouts (C:N = 14), mustard (C:N = 10), or broccoli residues (C:N = 14) (EFR >35 mg N 2 O-N/g residue-N in 78 days) and Ruser et al ( 2009 ) for mustard residues (EFR 31–37 mg N 2 O-N/g residue-N in a year). It is noticeable that all of these studies feature crop residues with C:N ratios <25 as was the case in the present study (C:N = 12).…”

SUMMARYVegetable production systems are often characterized by excessive nitrogen (N) fertilization and the incorporation of large amounts of post-harvest crop residues. This makes them particularly prone to ammonia (NH3) and nitrous oxide (N2O) emissions. Yet, urgently needed management strategies that can reduce these harmful emissions are missing, because underlying processes are not fully understood. The present study therefore focuses on the effects of residue placement on NH3 and N2O emissions. For this, cauliflower leaf residues (286 kg N/ha) were either applied as surface mulch (mulch) or mixed with the topsoil (mix) and in situ NH3 and N2O emissions were investigated. The experiment took place on a sandy soil in Northeastern Germany during summer 2012. Residue application created a high peak in N2O emissions during the first 2 weeks, irrespective of residue placement. There was no significant difference in the emission sums over the experimental period (65 days) between the mix (5·8 ± 0·68 kg N2O-N/ha) and the mulch (9·7 ± 1·53 kg N2O-N/ha) treatment. This was also the case for NH3 emissions, which exhibited a lower initial peak followed by a prolonged decline. Measured emission sums were 4·1 ± 0·33 (mix) and 5·1 ± 0·73 (mulch) kg NH3-N/ha. It was concluded that substantial NH3 and N2O emissions can occur after high input of available organic carbon and N even in a coarse-textured soil with low water-holding capacity. Other than expected, surface-application does not enhance NH3 emissions at the expense of N2O emissions compared with residue mixing into the soil, at least under the conditions of the present study.

“…This may be explained by immobilization of N with increasing C/N ratio of the crop residues (Abalos et al ., ). The oxidation rate is greater immediately after the incorporation of vegetative material (compared with cereal residues) due to quick decomposition, thus possibly promoting larger denitrification rates (Nicolardot et al ., ; Rizhiya et al ., ). Greater GHG emissions from low‐C/N‐ratio crop residue incorporation were observed in individual studies under field conditions in our analysis (e.g.…”

Incorporation of crop residues (CR) may be a sustainable 32 management practice to maintain the SOC levels and to increase soil fertility. This study 33 quantifies the effects of CR incorporation on SOC and greenhouse gas (GHG) emissions (CO2 and 34 N2O) in Europe using data from long-term experiments. Response ratios (RRs) for SOC and GHG 35 emissions were calculated between CR incorporation and removal. The influences of 36 environmental zones (ENZs), clay content and experiment duration on the RRs were 37 investigated. We also studied how RRs of SOC and crop yields were correlated. A total of 718 RRs 38 were derived from 39 publications. The SOC increased by 7 % following CR incorporation. In 39 contrast, in a subsample of cases, CO2 emissions were six times and N2O emissions 12 times 40 higher following CR incorporation. The ENZ had no significant influence on RRs. For SOC 41 concentration, soils with a clay content >35 % showed 8 % higher RRs compared to soils with 42 clay contents between 18 and 35 %. As the experiment progressed, RR for SOC concentration 43 and stock increased. For N2O emissions, RR was significantly higher in experiments with a 44 duration <5 years compared to 11-20 years. No significant correlations were found between RR 45 for SOC concentration and yields, but differences between sites and study durations were 46 detected. We suggest a win-win scenario to be crop residue incorporation for a long duration in 47 a continental climate, whereas the worst-case scenario involves crop residue incorporation over 48 the short term in the Mediterranean, especially with vegetative material. We conclude that CR 49 incorporation is important for maintaining SOC, but its influence on GHG emissions should be 50 taken into account as well. 51 52 Availability: This is the author's manuscript

“…Accumulation of nitrates, which is the result of the process of nitrification, was higher at the beginning of our field studies and the rate of nitrification was greater in the soil with high than with medium fertility in all the treatments. That could be a result of higher mineral N content in the soil with high fertility as well as of higher microbial activity of the soil which was shown for the same soil by Rizhiya et al (2011).…”

Soils are one of the main sources of nitrous oxide (N 2 O) in agriculture. Soil management practices can significantly affect N 2 O emissions through changing soil physical, chemical and biochemical properties. Application of biochar to arable soils can be an option for N 2 O emission mitigation, but the effect of biochar can be different for soils with different fertility levels. The objective of this study was to evaluate the effect of biochar application on N 2 O emission, soil properties and barley yield from loamy sand Stagnic Luvisol with high and medium levels of fertility caused by high rates of farmyard manure and fertilizer application for 10 years. A small-scale field experiment was conducted during the growing season of 2012 in NorthWestern Russia. Four treatments were used in the experiment: 1) control (no biochar, no N-fertilizer), 2) biochar (12 t ha-1), 3) N-fertilizer (90 kg ha-1 N) and 4) biochar (12 t ha-1) + N-fertilizer (90 kg ha-1 N), in five replicates. Significant changes in water-holding capacity and the amount of available nitrogen (N) occurred in the soil with high fertility, and thus it emitted significantly more N 2 O for the growing season than the soil with medium fertility. Biochar application effect on N 2 O emissions depended on the soil management history and was reducing the emission from the soil with high fertility rich in mineral N and C but not from the soil with medium fertility if no nitrogen fertilizer was applied to the latter soil. The yield-scaled N 2 O emission was the highest from the control treatments for the soil with both fertility levels, and the soil with high fertility was always characterized by higher yield-scaled N 2 O emissions than the soil with medium fertility. Application of biochar reduced yield-scaled N 2 O emission from the soil with medium and high fertility levels showing that biochar application to the soil can improve N use by the plants.
