Title
Effects of Nitrapyrin on Corn Yields and Recovery of Ammonium‐N at 18 Site‐Years in Iowa
M. E. Cerrato; A. M. Blackmer jpa 1990. doi:10.2134/jpa1990.0513
Other claims from this paper (5)
- Intervention effect Nitrapyrin significantly increased corn yields at only two of the 72 rate-site-years
- Intervention effect Nitrapyrin did not influence recovery of labeled N in grain at 22 of 24 rate-site-years
- Intervention effect Nitrapyrin decreased recovery of labeled N at the two other rate-site-years
- Intervention effect Nitrapyrin had no significant effect on labeled N recovery in soils 8 weeks and 14 months after application
- Recommendation Nitrapyrin use was not cost effective for corn producers at any of the sites studied
