Other claims from this paper (8)
- Intervention effect P fertilization increased corn yields every study year.
- Intervention effect Zn fertilization raised mean corn yield by 2 bu/acre over 26 years.
- Intervention effect Corn yield response to Zn was similar across applied P levels in most years.
- Intervention effect Highest P application raised soil test P several times beyond yield optimizing levels.
- Intervention effect Zn fertilization raised initially marginal available Zn to very high levels.
- Intervention effect Zn fertilization increased yields in 5 of 26 years.
- Recommendation Excess P fertilization would reduce producer profits.
- Recommendation Excess P would not raise Zn fertilizer need.
