- Observation Soil carbon fell 15·3 t/ha between 1996 and 1999.
- Observation Deep ploughing had estimated CO2 losses of 3·1 t/ha.
- Observation Normal ploughing had estimated CO2 losses of 4·5 t/ha.
- Observation No tillage had estimated CO2 losses of 4·6 t/ha.
- Observation Fertilized spring barley under no tillage had the highest N2O fluxes.
- Intervention effect No tillage failed to reduce carbon emissions.
- Intervention effect No tillage increased N2O emissions.
- Intervention effect No tillage required more nitrogen fertilizer than ploughing.
- Intervention effect Deep ploughing reduced carbon emissions.
- Intervention effect Deep ploughing reduced N2O emissions.
- Observation Subsoil denitrification losses were estimated at 10–16 kg N/ha per year.
- Intervention effect Net nitrogen mineralization was lower with nitrogen fertilizer than without it.
