Other claims from this paper (6)
- Method / resource Direct LAI and estimated PAI were highly correlated, with R2 = 0.93.
- Method / resource The tested protocol had the lowest RMSE, 0.21.
- Method / resource Eight measurements below the canopy were sufficient for accurate LAI estimation.
- Method / resource Applying the empirical calibration equation yielded accurate LAI estimates.
- Recommendation Local calibration is required for the estimation method.
- Recommendation The method is recommended for rapid, precise LAI estimation and canopy management decisions.
