Abstract: It is imperative for sustainable agriculture to explore practices and inputs creating low N 2 O emission capacity without reducing the productivity of the agricultural system. To evaluate different nutrient management schemes, a microcosm study was conducted to assess the direct N 2 O emission from soil. Four different treatments were used to provide a preliminary assessment of N 2 O emissions, as well as the concentrations of nitrates (NO 3 −) and ammonium (NH 4 +) produced in soil: compost (derived from green plant residues), chickpea residues (green manure) in two different N concentrations (2.6% and 5.5%, respectively) and ammonium nitrate (fertilizer). The soil was thoroughly mixed with the organic amendments and ammonium nitrate and incubated for 31 days. The emissions of N 2 O were higher in green manure with high-N content, as a source of nitrogen in the soil, and were similar to the emissions measured from the chemically fertilized soil. In particular, chickpea residues, with high-N content, exhibited cumulative N 2 O emissions, equal to 266.17 μg N/m2, whereas in fertilized soil the emissions were 267.10 μg N/m2. On the contrary, the incorporation of chickpea plant residues with low-N content can be an efficient way to minimize the N 2 O emissions at 21.63 μg N/m2. The emissions of N 2 O when compost was applied, remained relatively low, equal to 5.47 μg N/m2, and in comparison to soil without any treatment. Overall, a positive association between NH 4 +, NO 3 − in soil and N 2 O emissions were observed. However, this response was treatment depended, and the significant positive correlation between NH 4 + and N 2 O emissions were noticed in soils treated with ammonium nitrate, chickpea residues with low N content, as well as untreated controls. On the contrary, the positive correlation observed between NO 3 − and N 2 O emissions in soils receiving compost and high N chickpea residues, suggest that the different treatments are differentially affecting the processes that are contributing to N 2 O emissions in agricultural soils. These findings, emphasize that the different nutrient management schemes are differentially affecting the main process contributing to N 2 O emissions in agricultural soils. • A microcosm study with four nutrient management schemes was performed. • Direct N 2 O emission with nitrates and ammonium concentrations were measured in soil. • The highest emissions of N 2 O were obtained in green manure and fertilizer. • NH 4 + positive correlation and NO 3 − negative towards N 2 O emissions was noticed. • Combination of compost with different organic amendments could low N 2 O emissions.
