- •
Exporting all harvestable straw reduced soil C stocks.
- •
The soil C loss was highly affected by the initial C content.
- •
Some of the soil C loss was offset by using oil radish catch crop and early sown wheat.
- •
Oil radish catch crops and early sown wheat reduced N leaching losses.
- •
Early sowing reduced N leaching and N2O emission more than oil radish catch crop.
