ISHS Acta Horticulturae 274: International Symposium on Diagnosis of Nutritional Status of Deciduous Fruit Orchards
USING LEAF ANALYSIS RESULTS TO MANAGE MATURE MCINTOSH APPLE TREES |
| Authors: | E.N. Estabrooks, I. Ghanem |
| Abstract:
A McIntosh apple research orchard, planted in 1972 and fruiting since 1976, was monitored for nutrients by leaf analysis, block by block, during the past six years. Changes in leaf nutrient levels were attributed to changes in crop load and fertilizer applications. Differences in nutrient uptake were detected between the rootstocks used in the orchard. Leaf analysis results in the research orchard were compared to commercial apple plantings in the region. | |
