SGS-LTER Historical LTER Soil water - neutron probe: field data (1984-1992) in Section 15, Sandy 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. Additional information and referenced materials can be found: http://hdl.handle.net/10217/82912,,

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. Our objective in this study was to evaluate effects of land use on in situ net N mineralization in shortgrass steppe by comparing native and abandoned fields and cultivated fields, and by comparing soil under and between plants within native and abandoned fields. We also compared mineralization patterns between in situ and laboratory incubations to evaluate the role of environmental restrictions in determining N supply across management treatments and microsites.

Soil Moisture Neutron Probe Data (FIFE)
공공데이터포털
The neutron-probe data present a series of measurements of volumetric water content in the soil profile compiled using the neutron method. These data were collected from throughout the FIFE study area from May 1987 through August 1989. The neutron method of measuring soil water content uses the principle of neutron thermalization. When both hydrogen and oxygen are considered, water has a marked effect on slowing or thermalizing neutrons. Thermal neutron density is easily measured with a detector, if the capture cross-section remains constant then the thermal neutron density may be calibrated against water concentration on a volume basis.

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. Our research on abandoned fields at the CPER has two aspects,vegetation recovery and soil recovery. We wish to monitor these fields for the tem of the LTER project (decades or centuries), and to address some specific research questions. Our questions are: 1. Does vegetation on shortgrass steppe recover 55 years following cultivation? Specifically, does Bouteloua gracilis, the dominant shortgrass steppe species, recover? Prior results indicated that B. gracilis reovers on some fields, and does not on others. The fields that do not are dominated by buffalo grass. In this new work at the CPER, we ask an additional question: 2. What determines whether B. gracilis recovers? 3. Does soil organic matter recover following abandonment? Specifically, do indices of soil fertility such as nitrogen availability recover? 4. Does small-scale patterning associated with individual plants recover following disturbance? 5. Does the rate of soil recovery depend upon the rate of vegetation recovery? Past results on the Pawnee National Grasslands indicated that only small amounts of organic matter had accumulated following abandonment but that nitrogen availability had recovered to its original levels under B. gracilis plants on the abandoned fields. Specifically, we are interested in whether it makes a difference to soils if blue grama recovers or not.
