Other claims from this paper (5)
- Intervention effect At above-optimal nitrogen levels, adding a nitrification inhibitor increased average corn yields by 5%.
- Intervention effect Over the whole study, adding 1.12 kg/ha of nitrapyrin to manure increased corn yields the most compared with other inhibitor levels or etradiazol.
- Intervention effect Soil nutrient levels did not increase from the manure applications.
- Intervention effect There was a lower incidence of stalk rot in corn when nitrification was inhibited.
- Mechanism The response to the higher nitrogen rate indicated that more N was applied than needed for grain production, partially compensating for N loss.
