Other claims from this paper (14)
- Intervention effect Nitrapyrin was effective in decreasing the nitrification rate of both fall- and spring-applied N.
- Intervention effect With nitrapyrin, an average of 12% of fall-applied N was recovered as ammonium from the top 15 cm of soil in early June, whereas fall-applied N without nitrapyrin was nitrified by mid-March.
- Intervention effect More ammonium-N was recovered from soil in early June when N was applied in the fall with nitrapyrin than in the spring without nitrapyrin.
- Intervention effect Nitrate accumulated at 45 cm depth when fall urea had no nitrapyrin, but did not accumulate below 15 cm when urea was applied in the fall with nitrapyrin or in the spring with or without nitrapyrin.
- Intervention effect Nitrapyrin did not affect the concentration of P, K and Ca in the ear leaf, grain or stover.
- Intervention effect Nitrapyrin did not affect the concentration of Mg, Cu and B in the ear leaf, grain or stover.
- Intervention effect Nitrapyrin did not affect the concentration of Mn in the ear leaf, grain or stover.
- Intervention effect Nitrapyrin increased the concentration of Fe in the ear leaf by 10%.
- Intervention effect Nitrapyrin added with 67 kg/ha fall-applied N increased N concentration in the ear leaf by 15%.
- Intervention effect With spring-N, nitrapyrin increased the spring-N concentration in the stover by 13%.
- Intervention effect With spring-N, nitrapyrin increased the spring-N concentration in the grain by 17%.
- Intervention effect Nitrapyrin applied with 134 kg/ha spring N increased N concentration in the ear leaf by 14%.
- Intervention effect Nitrapyrin applied with 134 kg/ha spring N decreased N concentration in the grain by 11%.
- Intervention effect Nitrapyrin increased grain yield by 27% when applied with 67 kg/ha fall-N.
