本研究调查了在两种对比植被管理 (VM) 处理下，植被管理对生长在俄勒冈州中部海岸山脉 (CR) 的 16 至 18 年生花旗松 (DF)、西部铁杉 (WH)、西部红杉 (WRC) 和大冷杉 (GF) 林以及生长在俄勒冈州喀斯喀特山麓 (CF) 的 DF 和 WRC 的各种组织和生态系统组成部分的养分浓度的长期影响。处理包括：对照，种植后不施用除草剂；VM，施用五年的春季除草剂。两种处理都包括秋季场地准备除草剂的应用。生态系统分为作物树木（分为树叶、活枝、树皮和干木）、中层树种（分为树叶和茎）、林下植物、森林地面、细根和矿质土壤（深度增量为 0.0–0.2 m、0.2–0.4 m、0.4–0.6 m 和 0.6–1.0 m）。分析所有样品的总碳、氮、磷、钾、钙、镁、硫、硼、铜、铁、锰、钠和锌的浓度。这项研究设计报告了 1,740 个独特的营养浓度结果。 VM（处理）对组织浓度的影响因养分、植被作物种类（物种）、生态系统组成部分和地点而异。森林地面和作物树皮，其次是细根，是所有物种中显示出最多处理效果的生态系统成分养分浓度。不同地点的土壤浓度存在很大差异，但通常不受处理和物种的影响。在 CR 地点，不同物种的 VM 地块土壤镁和钙浓度较高，而锌浓度较低。处理对土壤养分浓度没有其他影响，但存在一些显着的处理与作物种类的相互作用。最值得注意的是，在 CF 站点，VM 地块中的 C 和 N 浓度高于 DF 的对照地块，而 WRC 的情况正好相反。虽然土壤总浓度通常不受处理的影响，并且从长远来看不太可能受到不利影响，但 VM 可能会减少 WRC 等生长缓慢物种的土壤氮。
This study investigates the long-term effects of vegetation management on nutrient concentration of various tissues and ecosystem components of 16 to 18 year-old Douglas-fir (DF), western hemlock (WH), western redcedar (WRC), and grand fir (GF) stands growing in Oregon’s central Coast Range (CR) and DF and WRC growing in Oregon’s Cascade mountain foothills (CF) under two contrasting vegetation management (VM) treatments. The treatments consist of: Control, which received no herbicide application post planting, and VM, which received five years of spring release herbicide application. Both treatments include a fall site preparation herbicide application. The ecosystem was broken down into crop trees (separated into foliage, live branches, bark, and stemwood), midstory species (separated into foliage and stem), understory, forest floor, fine roots, and mineral soil (with depth increments 0.0–0.2 m, 0.2–0.4 m, 0.4–0.6 m, and 0.6–1.0 m). All samples were analyzed for concentration of total carbon, nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, copper, iron, manganese, sodium, and zinc. This study design resulted in 1,740 unique nutrient concentration results being reported. The effect of VM (treatment) on tissue concentration varied by nutrient, overstory crop species (species), ecosystem component, and site. Forest floor and crop tree bark, followed by fine roots, were the ecosystem component nutrient concentrations that showed the greatest number of treatment effects across all species. Soil concentrations showed large variation across sites but were generally unaffected by treatment and species. At the CR site, magnesium and calcium soil concentrations were higher in VM plots across species, while zinc concentrations were lower. There were no other effects of treatment on soil nutrient concentrations, but there were some significant treatment × crop species interactions. Most notably, at the CF site, the concentration of C and N were higher in VM plots than control plots of DF, while the opposite was true for WRC. While total soil concentrations were generally unaffected by treatment and are unlikely to be adversely affected in the long term, it is possible that VM can reduce soil nitrogen for slow growing species like WRC.
