Title
Response of Soybeans Following Six Annual Applications of Various Levels of Boron, Copper, and Zinc1
D. C. Martens; M. T. Carter; G. D. Jones Agronomy Journal 1974. doi:10.2134/agronj1974.00021962006600010023x

- Intervention effect Six annual applications of boron up to 3.3 kg per hectare did not decrease soybean growth or seed yield.
- Intervention effect Six annual applications of zinc up to 11.1 kg per hectare did not decrease soybean growth or seed yield.
- Mechanism The authors partly attributed soybean tolerance to reduced micronutrient uptake at near-neutral soil pH.
- Intervention effect Six annual B, Cu and Zn applications did not raise soybean seed micronutrient concentrations to levels that preclude animal feed use.
