Nitrous Oxide Evolution from Agricultural Soil: A Regression Approach

【摘要】 <正> N₂O emission from soil is affected by many factors. In this study, N₂O flux, soil temperature, water content, NO₃^- and NH₄⁺ concentrations were simultaneously measured in winter wheat field. N₂O flux, NO₃^- and NH₄⁺ concentrations were all lognormally distributed, while water content was normally distributed. The relationship between N₂O flux and soil factors was also studied. N₂O flux was most highly correlated with soil temperature. Regression model was developed to explain the variability of N₂O emission from agricultural soil using multifactorial analysis.更多还原
