Conventional technology is virtually unable to measure complete GHG budgets of drained organic soils, which may provide misleading results. So, global estimates of GHG emissions are based on coarse assumptions that don’t take into account the complexity of agroecosystems. Better data are needed for evidence-based rulings on mitigation. By newly developed Relaxed Eddy Accumulation (REA) systems we will study complete, continuous GHG budgets (H2O, CO2, CH4, N2O, NH3) from 3 pairs of organic agricultural fields with contrasting peat layer depth and cultivation. This will shed new light on the climate impact of cultivated organic soils and the importance of site-specific conditions and management. High time resolution enables process studies to reveal key parameters and mechanisms that control GHG fluxes in the soil-plant-atmosphere system, which will significantly improve simulation models. This will notably improve GHG reporting, climate modeling, and the base for mitigation strategies.
Med konventionell mätteknik är det praktiskt taget omöjligt att mäta fullständiga växthusgasbudgetar från dränerad organogen mark, vilket kan ge missledande resultat. Därför baseras globala skattningar av växthusgasutsläpp idag på grova antaganden som inte tar hänsyn till agro-ekosystemens komplexitet. Bättre data behövs för evidensbaserad klimatpolitik. Genom nyutvecklade Relaxed Eddy Accumulation (REA) system kommer vi under 3 år att studera fullständiga, kontinuerliga växthusgasbudgetar (H2O, CO2, CH4, N2O, NH3) av 3 par av organogena åkrar som skiljer sig avsevärt m.a.p. torvlager och odling. Detta ger nya insikter i klimateffekterna av jordbruk på organogen jord. Hög tidsupplösning möjliggör även processtudier som avslöjar nyckelmekanismer och parametrar som styr växthusgasflöden i mark-växt-atmosfärssystemet. Detta förbättrar simulationsmodeller och därmed växthusgasrapportering, klimatmodellering, och beslutsunderlag för klimatåtgärder.

Just going to the bathroom is contributing to algae blooms and climate change. Sweden alone releases roughly 15400 tonnes of N and 240 tonnes of P into lakes, rivers and seas, through municipal wastewater (including after treatment). Urine contains 80% of the plant nutrients found in wastewater and …
