Residual effects of different fertilizers (mineral and organic) on the first pulses of carbon dioxide (CO2), nitric oxide (NO), and nitrous oxide (N2O) after rewetting dry soil with or without application of a mineral N fertilizer were studied in a laboratory experiment. Six months before this study was conducted the fields had received either manure + urea, manure, urea or no fertilizer. In the first phase the soil was rewetted with water simulating a summer shower (heavy rainfall in short time) and in the second phase with a urea solution simulating a mineral fertilization. There were not significant differences in trace gas emissions between earlier field treatments after soil was rewetted with water addition. However, after urea addition, plots that had received manure 6 months earlier showed smaller total emissions of N2O and NO compared to plots that had only received urea. The residual effect of manure can play an important role in carbon poor soils under arid-semiarid climate in mitigating atmospheric pollutants such us NO and N2O.
