Facilities Improvement, Andrews Experimental Forest: Automated CNS Analysis of Plant and Soil Samples

H. J.安德鲁斯实验森林是俄勒冈州立大学运营的一个跨学科研究站点，俄勒冈州立大学、华盛顿大学、美国林务局、美国环境保护局、美国地质勘探局和其他大学的合作研究人员积极使用该站点。该地点位于威拉米特国家森林，是美国国家科学基金会支持的17个长期生态研究地点之一，也是美国国家科学基金会本科生研究体验地点。PI要求支持一台CNS分析仪、一台土壤/组织样品磨机和一台用于数据采集的微型计算机。这些仪器将提供给该站植物/土壤分析实验室的常驻和访问调查员。拟议的仪器获取将增加实验室的硫分析能力，增加在该站进行的分析数量，减少可以分析的样品的大小，并降低化学分析的每个样品的成本。这些分析对于森林正在进行的木材分解和通过生态系统的化学通量的研究至关重要。该仪器的获得将对许多当前和未来的研究项目产生重大的有益影响。

The H. J. Andrews Experimental Forest is an interdisciplinary research site operated by Oregon State University, and actively used by collaborating researchers from OSU, the University of Washington, the U. S. Forest Service, the U.S. Environmental Protection Agency, USGS, and other universities. The site is located in Willamette National Forest, and is one of 17 NSF-supported Long-Term Ecological Research Sites and the venue for an NSF Research Experience for Undergraduates Site. The PI requests support for a CNS analyzer, a soil/tissue sample mill, and a microcomputer for data acquisition. These instruments would be available to resident and visiting investigators in the Station's Plant/Soil Analysis Lab. The proposed instrument acquisition would add sulfur analysis to the Lab's capabilities, increase the number of analyses performed at the Station, decrease the size of the samples that could be analyzed, and decrease the per sample cost of chemical analysis. These analyses are critical to the studies of wood decomposition and chemical flux through ecosystems that are underway at the Forest. Acquisition of this instrument will have a significant beneficial impact on many current and future research projects.
