Other claims from this paper (16)
- Intervention effect The O1 rotation yielded 83% of conventional yield.
- Intervention effect O2 had the same yield as conventional rotation despite much lower nutrient import.
- Intervention effect O3 intercrops reduced yield to 70% of conventional rotation.
- Intervention effect Organic onion yield was 60% of conventional yield.
- Intervention effect Organic carrot yield approached conventional yield.
- Intervention effect Organic oat yield approached conventional yield.
- Observation Onion rooting depth was below 0.4 m.
- Observation Cabbage rooting depth exceeded 2 m.
- Observation Rye rooting depth exceeded 2 m.
- Observation Fodder radish rooting depth exceeded 2 m.
- Intervention effect Cropping system did not affect root growth.
- Intervention effect O1 and O2 had almost identical yields.
- Intervention effect O1 and O2 had almost identical nitrogen uptake.
- Intervention effect O2 had lower subsoil nitrogen than conventional rotation.
- Intervention effect O2 had lower subsoil nitrogen than O1.
- Mechanism O2 was inferred to strongly reduce nitrogen leaching losses.
