Other claims from this paper (11)
- Intervention effect Liquid swine manure gave corn yields comparable to inorganic fertilizer.
- Intervention effect Solid swine manure gave inconsistent corn yield across years.
- Intervention effect Composted swine manure had minimal agronomical value for corn.
- Intervention effect Soybean with inorganic fertilizer had the highest grain yields, 3,468 and 3,761 kg ha −1 in 2005 and 2007.
- Observation Gain N removal of soybeans was comparable between the two alternative years.
- Method / resource N use efficiency indices NUE, NUpE and NUtE discriminated the manure effects on corn, but NPE and NHI did not.
- Method / resource N agronomic efficiency and N recovery efficiency discriminated the manure effects on corn.
- Method / resource N physiological efficiency and N harvest index did not discriminate the manure effects on corn.
- Observation Legacy effects from the preceding corn on soybean yield were detected by NAE and NRE.
- Intervention effect Inorganic fertilizer performed the best and liquid manure followed in grain yield together with N use efficiency parameters.
- Method / resource NUE, NUpE, NUtE, NAE and NRE used for chemical fertilizer N were also applicable to manure N efficiency.
