Dewey subsp. intermedium] is a high-yielding cool-season grass with adaptable uses for grazing, haying, and soil restoration. Despite its adaptability, adoption of intermediate wheatgrass has been limited due to inadequate stand longevity under grazing stress. A study was conducted near Mandan, ND USA to investigate if stand longevity of intermediate wheatgrass was affected by changes in soil properties due to grazing. Soil data from this study included measurements of soil bulk density, soil pH, soil organic carbon, and total soil nitrogen on a Wilton silt loam soil (USDA: Fine-silty, mixed, superactive frigid Pachic Haplustoll). Measurements were made in May 1997 (baseline) and again in May 2004 following four years of grazing. Data may be used to understand soil property responses to grazed perennial forages. Data are generally applicable to rainfed conditions under a semiarid Continental climate for the following associated soil types: Temvik, Grassna, Linton, Mandan, and Williams.</p>\n<p>Resources in this dataset:</p>\n<p>Resource title: Intermediate Wheatgrass Grazing Study Data Dictionary\nFile name: IWGS_Data Dictionary.xlsx\nResource description: Data dictionary for associated dataset.</p>\n<p>Resource title: Intermediate Wheatgrass Grazing Study_Soil Data for Aggregated Depths\nFile name: IWGS_Soil Data_Aggregated Depths.xlsx\nResource description: File includes data for 0-30 cm depth.</p>\n<p>Resource title: Intermediate Wheatgrass Grazing Study_Soil Data for Separated Depths\nFile name: IWGS_Soil Data_Separated Depths.xlsx\nResource description: Soil data for 0-5, 5-10, 10-20, and 20-30 cm depths.</p>\n<p>Resource title: Intermediate Wheatgrass Grazing Study_Soil Data_Aggregated Depths\nFile name: IWGS_Soil Data_Aggregated Depths.csv\nResource description: Data for aggregated depths in csv format.</p>\n<p>Resource title: Intermediate Wheatgrass Grazing Study_Metadata_Aggregated Depths\nFile name: IWGS_Soil Data_Aggregated Depths_Metadata.csv\nResource description: Metadata for aggregated depths.</p>\n<p>Resource title: Intermediate Wheatgrass Grazing Study_Soils Data_Separated Depths\nFile name: IWGS_Soil Data_Separated Depths.csv\nResource description: Soil data for 0-5, 5-10, 10-20, and 20-30 cm depths.</p>\n<p>Resource title: Intermediate Wheatgrass Grazing Study_Metadata_Separated Depths\nFile name: IWGS_Soil Data_Separated Depths_Metadata.csv\nResource description: Metadata for soils data separated by depth increment.</p>", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "https://ndownloader.figshare.com/files/44541314", "format": "xlsx", "mediaType": "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", "title": "IWGS_Data Dictionary.xlsx"}, {"@type": "dcat:Distribution", "downloadURL": "https://ndownloader.figshare.com/files/44541317", "format": "xlsx", "mediaType": "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", "title": "IWGS_Soil Data_Aggregated Depths.xlsx"}, {"@type": "dcat:Distribution", "downloadURL": "https://ndownloader.figshare.com/files/44541320", "format": "xlsx", "mediaType": "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", "title": "IWGS_Soil Data_Separated Depths.xlsx"}, {"@type": "dcat:Distribution", "downloadURL": "https://ndownloader.figshare.com/files/44541323", "format": "csv", "mediaType": "application/csv", "title": "IWGS_Soil Data_Aggregated Depths.csv"}, {"@type": "dcat:Distribution", "downloadURL": "https://ndownloader.figshare.com/files/44541326", "format": "csv", "mediaType": "text/plain", "title": "IWGS_Soil Data_Aggregated Depths_Metadata.csv"}, {"@type": "dcat:Distribution", "downloadURL": "https://ndownloader.figshare.com/files/44541329", "format": "csv", "mediaType": "application/csv", "title": "IWGS_Soil Data_Separated Depths.csv"}, {"@type": "dcat:Distribution", "downloadURL": "https://ndownloader.figshare.com/files/44541332", "format": "csv", "mediaType": "text/plain", "title": "IWGS_Soil Data_Separated Depths_Metadata.csv"}], "identifier": "10.15482/USDA.ADC/1529800", "keyword": ["Perennial forages", "Northern Great Plains", "soil organic carbon", "soil pH", "soil bulk density", "NP215", "data.gov", "ARS"], "license": "https://www.usa.gov/publicdomain/label/1.0/", "modified": "2025-11-21", "programCode": ["005:040"], "publisher": {"@type": "org:Organization", "name": "Agricultural Research Service"}, "spatial": "{\"type\": \"Point\", \"coordinates\": [-100.90610013015, 46.776374053019]}", "temporal": "1997-05-01/2004-05-01", "title": "Data from: Soil resistance under grazed intermediate wheatgrass"}
