Glen R. Obear; William C. Kreuser; Ken Hubbard; et al. Crop Science 2017. doi:10.2135/cropsci2016.05.0440
Other claims from this paper (10)
- 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.
- Recommendation The authors advise against reflectance indices for plant health under colorant or iron.
