This is a soil analysis data file prepared by the Illinois Department of Natural Resources documenting soil sample results from Chauncey Marsh State Natural Area, a state-owned agricultural property. The file contains geographic coordinates for 14 soil sampling locations within Field ID 3485 and presents comprehensive soil chemistry test results from samples collected on May 2, 2023, and reported on May 3, 2023. The samples were analyzed for standard soil metrics including pH, phosphorus, potassium, calcium, magnesium, sulfur, boron, copper, iron, manganese, zinc, sodium, organic matter, and estimated nitrogen release, with results reported in parts per million (ppm), percentages, and pounds per acre. Sample locations were distributed across multiple sub-sections of the field (3485-6, 3485-9, 3485-10, and 3485-18), with latitude and longitude coordinates ranging from approximately 87.79° to 87.80° west longitude and 38.86° to 38.87° north latitude.

The soil data reveals generally neutral to slightly acidic conditions across the site, with pH values ranging from 5.1 to 7.0 and buffer pH readings from 6.67 to 6.87. Cation exchange capacity (CCEC) values ranged from 4.4 to 9 meq/100g, indicating variable soil fertility characteristics across the field. Organic matter content was consistent across samples at approximately 13 to 15 percent, while phosphorus levels were generally low to moderate (3 to 17 ppm) and potassium levels varied considerably (44 to 86 ppm). Report number 23-122-0593 was assigned to all samples, indicating a single comprehensive testing event. This soil data would support agricultural lease bidding by providing potential farmers with detailed baseline information regarding soil conditions, nutrient availability, and management requirements for the Chauncey Marsh State Natural Area property.
