Other claims from this paper (10)
- Method / resource The manifold prepared 3 kg ammonia at 1.2–1.5 atom % enrichment in a working day.
- Method / resource Collection capacity was 3000% above prior systems.
- Intervention effect Fall nitrogen raised grain yield by an average 46% at five sites.
- Observation Grain fertilizer nitrogen uptake efficiency ranged 12 to 34%.
- Observation Biomass fertilizer nitrogen uptake efficiency ranged 16 to 42%.
- Observation Fertilizer derived nitrogen never exceeded 50%.
- Intervention effect Nitrapyrin significantly increased uptake efficiency at only two sites.
- Intervention effect The experimental alternative did not significantly increase uptake efficiency.
- Association Soil organic carbon and mineralizable nitrogen differences had larger effects on corn labeled nitrogen uptake.
- Recommendation Accounting for soil nitrogen mineralization can improve uptake efficiency.
