SGS-LTER Historical LTER Soil water - neutron probe: lysimeter field data (1983-1992) on the Central Plains Experimental Range, Nunn, Colorado, USA, ARS Study Number 10

This data package was produced by researchers working on the Shortgrass Steppe Long Term Ecological Research (SGS-LTER) Project, administered at Colorado State University. Long-term datasets and background information (proposals, reports, photographs, etc.) on the SGS-LTER project are contained in a comprehensive project collection within the Digital Collections of Colorado (http://digitool.library.colostate.edu/R/?func=collections&collection_id=3429). The data table and associated metadata document, which is generated in Ecological Metadata Language, may be available through other repositories serving the ecological research community and represent components of the larger SGS-LTER project collection.
Long-term (1985-1992) dynamics and spatial variations in soil water below the evaporative zone were evaluated for a shortgrass steppe with a low and variable precipitation regime. Each of sandy loam, clay loam, and two sandy clay loam sites compromised a toposequence with upland, midslope, and lowland positions. Soil water was monitored at 15cm intervals providing estimates covering 22.5 to 97.5 cm depths. Soil water throughout the profile was highest in the clay loam and lowest in the sandy loam. However, stored soil water did not vary systematically among slope positions.

该数据集由从事科罗拉多州立大学管理的短草草原长期生态系统研究（SGS-LTER）项目的研究人员制作。关于SGS-LTER项目的长期数据集及背景信息（提案、报告、照片等）均收录于科罗拉多数字收藏馆的全面项目集中（http://digitool.library.colostate.edu/R/?func=collections&collection_id=3429）。该数据表及相关元数据文档，采用生态元语言编制，可能通过服务于生态研究领域的其他存储库获取，并代表SGS-LTER项目集的一部分。对1985年至1992年期间蒸发层下方土壤水分的长期（1985-1992）动态变化和空间变异进行了评估，研究对象为具有低且多变的降水模式的短草草原。每个砂壤土、壤土以及两个砂壤土地点构成了一个包括高地、中坡和低地位置的坡序。土壤水分在15cm的间隔内进行监测，提供了涵盖22.5至97.5cm深度的估计值。在整个土壤剖面中，壤土的土壤水分最高，砂壤土的土壤水分最低。然而，储存的土壤水分在不同坡位之间并未表现出系统性差异。更多信息及参考文献可查阅：http://hdl.handle.net/10217/82912。本数据集中包含的资源：资源标题：指向HTML文件的网站指针。文件名：网页，网址：https://portal.edirepository.org/nis/mapbrowse?scope=knb-lter-sgs&identifier=148 包含信息和数据文件下载链接的网页。
