To prevent chlorosis in chestnuts, Derick compared broadcasting and localized application of nutrient amendments to no amendment controls. After a year of growth, he measured tree height and leaf nutrient status.
In a Nutshell
- Derick detected no difference in plant health or leaf nutrient status between the two amendment methods. Given the extra labour involved with the localized treatment, he will not broadcast any amendments moving forward.
- He detected higher leaf potassium levels in the amended trees, which is important for iron availability in the plant.
