Liming reduces N2O emissions from Mediterranean soil after-rewetting and affects the size, structure and transcription of microbial communities

Popis výsledku v původním jazyce

In Mediterranean regions, the accumulation of nitrogenous substrates in soil during summer fallow period has been linked to pulses of N2O emissions upon soil rewetting. Although the mechanisms of N2O emission after soil rewetting have been previously studied, potential mitigation of agronomic practices on N2O pulses is still poorly understood. We studied the N2O emissions after rewetting of degraded soils managed by no tillage (NT) and conventional tillage (CT), both with or without lime application under laboratory conditions. The soil was rewetted to 50 and 100 percent of field capacity (FC) and the N2O fluxes, size, structure and gene transcription of the microbial communities involved in the N2O emissions were evaluated. Liming reduced the cumulative N2O emission by more than 70 and 65% respect to the unamended soil after soil rewetting to 50 and 100 percent of FC, respectively, whereas no significant effect of tillage on N2O emission was observed. Liming strongly influenced the size and structur
