Other claims from this paper (7)
- Method / resource Species composition models gave the best herbage yield predictions.
- Method / resource Ellenberg N-values and NMDS scores performed equally well.
- Method / resource Ellenberg N-values and NMDS scores outperformed R- and F-value models.
- Method / resource Soil-variable predictions were least accurate.
- Method / resource N-value models predicted productivity rank order accurately in 2002.
- Method / resource NMDS models predicted productivity rank order accurately in 2002.
- Method / resource Neither N-value nor NMDS models predicted actual site yield.
