Other claims from this paper (14)
- Intervention effect Reducing primary tillage intensity increased soil moisture and bulk density in the upper 0-10 cm layer.
- Observation In zero tillage soil the highest moisture and bulk density before pre-sowing tillage were 25.8% and 1.40 Mg m -3.
- Observation In zero tillage soil the highest moisture and bulk density after sowing until germination were 23.6% and 1.40 Mg m -3.
- Intervention effect Tillage intensity had no significant influence on soil moisture and bulk density in the deeper 10-20 cm layer.
- Intervention effect Sugar beet seed germination in shallow loosened soil was fourfold higher than in conventional ploughing over 6 years, significant in two experimental years.
- Intervention effect Germination of directly sowed seeds was 37% lower than with conventional ploughing.
- Intervention effect Zero tillage had no significant influence on sugar beet yield, ramification and root sucrose content.
- Intervention effect No-tilled soil had a significantly higher number of annual weeds (32%) than conventional ploughing.
- Intervention effect No-tilled soil had a significantly higher total number of weeds (29%) than conventional ploughing.
- Observation The number of weed species increased from 22 to 26.
- Observation The number of Chenopodium album increased from 11.3 to 22.1 plants per m2.
- Observation The number of Poa annua increased from 5.6 to 14.2 plants per m2.
- Observation The number of Taraxacum officinalis increased from 0.66 to 6.1 plants per m2.
- Observation Elytrigia repens became a widespread weed.
