Title
Effects of Crop and Weed Management on Density and Vertical Distribution of Weed Seeds in Soil
Melinda L. Hoffman; Micheal D. K. Owen; Douglas D. Buhler Agronomy Journal 1998. doi:10.2134/agronj1998.00021962009000060013xa
Other claims from this paper (9)
- Intervention effect Treatment effects on weed seed numbers were more repetitive in soybean/corn rotation than in continuous corn.
- Association Foxtails were the weed class most affected by the treatments.
- Association Tillage affected the vertical distribution of weed seeds in soil.
- Association Weed control practices regulated the quantity of weed seeds in the top 5 cm of soil.
- Association Seed numbers differed among soil depths when herbicides were banded or omitted.
- Association Seed numbers were uniform among soil depths when herbicides were broadcast.
- Observation In conventional tillage, weed seeds were uniformly distributed among sampling depths.
- Observation In reduced tillage, weed seeds were concentrated near the soil surface.
- Recommendation Reducing weed seed deposition could help maintain weed seed numbers in reduced tillage systems at levels similar to intensively tilled systems.
