- Method / resource Visual and reflectance measures detected nitrogen rate differences.
- Method / resource With colorant, reflectance methods no longer detected N rate differences.
- Method / resource With iron, reflectance methods no longer detected N rate differences.
- Intervention effect Four colorants increased visual color ratings.
- Intervention effect Harmonizer increased CI.
- Intervention effect Foursome increased CI.
- Intervention effect Turf Screen did not increase CI.
- Intervention effect Green Lawnger did not increase CI.
- Intervention effect Three of four pigments decreased leaf chlorophyll content.
- Observation Six colorants reflected red and NIR light.
