Ecological assessment of spatial variation and seasonal dynamics of N2O and CH4 flows from soil in urban conditions

The article considers the ecological assessment of the seasonality of greenhouse gas emissions such as methane and nitrogen oxide (I), their spatial variation depending on the microrelief, which affects the conditions of humidification, in urban conditions in the planting of Purple Willow (Salix purpurea) at the Ecological Station of the Russian State Agrarian University-Moscow State Agricultural Academy named after K.A. Timiryazev. The assessment took into account indicators such as soil temperature and humidity, which are the determining characteristics in the intensity of emission fluxes of methane and nitrogen oxide(I) from soils. The dependence of seasonality on the emission of N2O and CH4 fluxes in various microrelief variants in the plantings of the Purple Willow (Salix purpurea) in the city has been established.
