- Observation Long-term liming was associated with disappearance of dominant acidophilic weeds from crop communities.
- Observation Naturally acid soil had 14.2 times greater weed seed contamination.
- Observation Vertical weed seed distribution was similar across soil depths regardless of pH.
- Intervention effect Long-term conventional ploughing reduced crop weediness in low-acidity soil.
- Intervention effect Reduced tillage had 1.6 times greater weed number.
- Intervention effect Reduced tillage had 1.4 times greater weed mass.
- Association Regular tillage changed vertical weed seed distribution with loosening depth.
- Observation Under reduced tillage, the upper 0-10 cm had the most weed seeds.
