Other claims from this paper (6)
- Method / resource Dead forage and accumulated degree days explained 75.9% of standing-crop nitrogen variation.
- Method / resource The fitted equation had prediction error variance of 0.026.
- Method / resource The regression coefficient of observed on predicted nitrogen was 0.995 +/- 0.125.
- Method / resource The validation intercept did not differ from zero.
- Method / resource Validation prediction error variance was 0.042.
- Recommendation The authors say the equation can predict forage nitrogen in Northern Great Plains rangelands.
