- Description:
- Eight "single tree" multi-nutrient screening trials were established on granite, granodiorite, tonalite, and basalt rock types in central Idaho. Foliar nutrient concentrations, contents, and needle weights ofindividually fertilized ponderosa and lodgepole pine [Pinus ponderosa (Law.) and Pinus conlorla var. loti/olio (Engelm.) trees were examined one year following multi-nutrient fertilization. Diagnosis and interpretation ofnutrient status using graphical vector analysis identified that N, S. and B were deficient at every research site. Significant needle weight increases, up to 47%, were observed over the control needle weights from application ofN, NKS + micros. or NPKSMg + micros fertilizer treatments. Vector analysis also identified Mg deficiencies on tonalite lithologies, K deficiencies on granodiorite lithologies, and eu and Zn deficiencies on basalt and tonalite lithologies. respectively. Screening trials proved effective in determining nutrient deficiencies across soil parent materials on similar habitat types within one growing season. Untreated foliar nutrient concentrations were significantly different between rock types and rock mineralogy and soil textural differences combined to explain tree foliar nutrient diO'erences for some elements.
