Other claims from this paper (10)
- Observation Over 60% of weed seed in the top 19 cm of soil was in the top 1 cm under no-tillage at both sites.
- Association Weed seed concentration declined logarithmically with increasing depth under no-tillage.
- Observation Under chisel plowing, over 30% of weed seed was in the top 1 cm of soil.
- Association Under chisel plowing, weed seed concentration decreased linearly with depth.
- Observation Moldboard plowing gave a uniform distribution of weed seed in the top 19 cm of soil.
- Intervention effect Preemergence metolachlor plus atrazine decreased weed seed population by 50% compared with no treatment over all tillage systems.
- Intervention effect One year of herbicide plus handweeding did not reduce seed numbers in chisel or moldboard plowing compared with herbicide alone.
- Intervention effect No-tillage with weed-free conditions decreased seed numbers by 40% relative to herbicide alone.
- Intervention effect Common lambsquarters germination was 40% greater under moldboard and chisel plowing than under no-tillage.
- Association Germination was highest for seed taken from 9 to 19 cm deep under moldboard plowing.
