Title

Other claims from this paper (6)
- Association Green wheel tracks were correlated with lower soil and leaf tissue nitrate.
- Intervention effect Added nitrogen decreased soybean grain yield with or without oats.
- Intervention effect An oat companion crop increased soybean yield at one of four sites.
- Intervention effect An oat companion crop decreased soybean yield at the moisture-limited site.
- Mechanism The authors consider nitrate a significant inducer of soybean iron deficiency chlorosis.
- Mechanism The authors suggest variation in nitrate and bicarbonate explains much of the year-to-year field variation in chlorosis.
