Other claims from this paper (19)
- Intervention effect Reduced tillage left more SOM in the top than bottom plough layer, opposite to conventional tillage.
- Intervention effect Earthworm abundance in NIT was 153% of CT.
- Intervention effect Earthworm abundance in ST was 235% of CT.
- Intervention effect Earthworm abundance in NT was 206% of CT.
- Intervention effect Earthworm biomass in NIT was 269% of CT.
- Intervention effect Earthworm biomass in ST was 325% of CT.
- Intervention effect Earthworm biomass in NT was 475% of CT.
- Intervention effect Epigeic earthworms were more affected by tillage than endogeic earthworms.
- Intervention effect Earthworm biomass was higher with CT-prolonged than CT.
- Observation Earthworm populations recovered over time regardless of tillage intensity.
- Intervention effect Soil penetration resistance was higher under reduced tillage than CT.
- Intervention effect Maize yields under NIT and ST were similar to CT.
- Intervention effect Maize yield under NT was lower than CT, by 19%.
- Intervention effect Maize yield under CT-prolonged was lower than CT.
- Intervention effect Maize yield under ST-prolonged was lower than CT.
- Intervention effect Maize yields did not differ between CT-prolonged and ST-prolonged.
- Intervention effect Harvested prolonged cover crop biomass closed the yield gap with CT in four of six years.
- Recommendation The authors recommend strip tillage for continuous maize cropping on Dutch sandy soils.
- Recommendation For severe compaction, the authors recommend conventional tillage with a prolonged cover crop and short-season maize.
