“…The patterns of gas emissions are complex and too few data are currently available to be included into models and scenario studies. Comparing this study with the results reported by Dick et al (2008) and by Sanchez-Martin et al (2008) demonstrates that residual organic C in the soil could be an important tool in arid-semiarid soils for mitigating N 2 0 and NO emissions and at the same time increasing the general fertility of the soil.…”

“…Nitric oxide (NO) fluxes were analysed by chemiluminescense (42C NOx analyser, Thermo Environmental Instruments Inc Franklin, MA, USA) using a gas flow-through system, as described in detail by Sanchez-Martin et al (2008). Flux measurements from soil columns were recorded at 10 sec intervals on a datalogger (Campbell Scientific 21x) until the system reached steady state conditions, approximately 20 min.…”

Residual effects of different fertilizers (mineral and organic) on the first pulses of carbon dioxide (C0 2 ), nitric oxide (NO), and nitrous oxide (N 2 0) 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 N 2 0 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 N 2 0.

“…Thus, under CT the CO 2 emissions were greater with the use of organic fertilizer compared with either the use of mineral fertilizers or in absence of fertilization. The application of pig slurry usually enhances the amount of readily decomposable C compounds in the soil (Arcara et al, 1999;Sánchez-Martín et al, 2008;Yang et al, 2003). This fact was observed in our experiment, in which a higher WSC content was measured in the macroaggregates of the pig slurry treatment.…”

Agricultural management practices play an important role in greenhouse gases (GHG) emissions due to their impact on the soil microenvironment. In this study, two experiments were performed to investigate the influence of tillage and N fertilization on GHG production at the macroaggregate scale. In the first experiment, soil macroaggregates collected from a field experiment comparing various soil management systems (CT, conventional tillage; NT, no-tillage) and N fertilization types (a control treatment without N and mineral N and organic N with pig slurry treatments both at 150 kg N ha -1 ) were incubated for 35 days. Methane (CH 4 ), carbon dioxide (CO 2 ) and nitrous oxide (N 2 O) production was quantified at regular time intervals by gas chromatography. In the second experiment, the effects of fertilization type and soil moisture on the relative importance of nitrification and denitrification processes in N 2 O emission from soil macroaggregates were quantified. Nitrate ammonium, macroaggregate-C concentration, macroaggregate water-stability, microbial biomass-C and N (MBC and MBN, respectively) and water-soluble C (WSC) were determined.While NT macroaggregates showed methanotrophic activity, CT macroaggregates acted as net CH 4 producers. However, no significant differences were found between tillage systems on the fluxes and cumulative emissions of CO 2 and N 2 O. Greatest cumulative CO 2 emissions, macroaggregate-C concentration and WSC were found in the organic N fertilization treatment and the lowest in the control treatment. Moreover, a tillage and N fertilization interactive effect was found in macroaggregate CO 2 production: while the different types of N fertilizers had no effects on the emission of CO 2 in the NT macroaggregates, a greater CO 2 production in the CT macroaggregates was observed for the organic fertilization treatment compared with the mineral and control treatments.The highest N 2 O losses due to nitrification were found in the mineral N treatment while 2 denitrification was the main factor affecting N 2 O losses in the organic N treatment. Our results suggest that agricultural management practices such as tillage and N fertilization regulate GHG production in macroaggregates through changes in the proportion of C and N substrates and in microbial activity.

Streszczenie: Celem pracy by³a ocena efektywnooeci i mo¿liwooeae wdro¿enia praktyk mitygacji emisji N 2 O w warunkach glebowoklimatyczno-agrotechnicznych Polski. Analizie poddano praktyki polegaj¹ce na: zmniejszeniu dawki azotu, doborze jego formy w nawozach i zastosowaniu inhibitorów biologicznych przemian zwi¹zków azotowych w glebie, regulacji odczynu gleby, kontroli i zmniejszeniu dawek nawozów naturalnych, zalesianiu gleb najs³abszych. Analiza dostêpnych danych wykaza³a, ¿e warunki sprzyjaj¹ce intensywnej emisji N 2 O z gleb uprawnych Polski wystêpuj¹ incydentalnie. Z tego powodu efektywnooeae praktyk polegaj¹cych na ekstensyfikacji produkcji rooelinnej mo¿e byae ma³a. Zmniejszenie poziomu nawo¿enia mo¿e przynieoeae po¿¹dany efekt mitygacyjny tylko w niewielkiej liczbie gospodarstw rolnych z intensywn¹ produkcj¹ roln¹. Poniewa¿ gleby zakwaszone s¹ postrzegane jako "hot spots" o podwy¿szonej emisji N 2 O, regulacja ich odczynu powinna byae traktowana jako praktyka mitygacji emisji tlenku diazotu o szerokim zastosowaniu ze wzglêdu na skalê zakwaszenia gleb Polski. Efektywn¹ praktyk¹ ograniczenia emisji N 2 O z gleb rolnych mo¿e byae zastosowanie inhibitorów nitryfikacji lub ureazy oraz zalesianie gleb ornych najs³abszych (VI klasa bonitacyjna). Wdro¿enie tych praktyk mo¿e byae ograniczone wzglêdami ekonomicznymi oraz przestrzenno-czasowym wymiarem planów zwiêksze-nia lesistooeci kraju. Uwzglêdnienie efektów mitygacyjnych analizowanych praktyk wymaga weryfikacji algorytmów wykorzystywanych do kalkulacji emisji gazów cieplarnianych (GHG).S³owa kluczowe: emisja N 2 O, zmniejszenie emisji GHG, gleby uprawne
