Soil nitrous oxide emissions from Eucalyptus plantation in Argentina por Alvarez, Carina Rosa, Rimski-Korsakov, Helena, Lupi, Ana Maria, Romaniuk, Romina Ingrid, Cosentino, Vanina Rosa Noemi, Ciarlo, Esteban Ariel, Steinbach, Haydeé S.

“…NO3-N level in soil was the variable that best explained N2O-N emissions (p < 0.001). Since nitrate content and CO2 emission were the variables most associated with nitrous emissions, it can be hypothesized that in clay soils greater emissions can be originated by higher nitrification as a result of their higher organic matter content or due to a deni trification provoked by the depletion of oxygen in a high consumption respiration process, and poor oxygen renewal caused by the increased amount of micro-aggregates and pores.…”
