This file is a soil analysis spreadsheet prepared by the Illinois Department of Natural Resources for the Black Crown Marsh State Natural Area located within Moraine Hills State Park. The spreadsheet documents soil sampling data collected on December 1, 2021, and processed on December 3, 2021, from four sample locations across Agricultural Lease Site 2459. The data includes geographic coordinates (latitude and longitude) for each sampling point and comprehensive soil chemistry results measuring pH levels, nutrient concentrations (phosphorus, potassium, calcium, magnesium, sulfur, boron, copper, iron, manganese, and zinc), organic matter content, and cation exchange capacity. All four samples were analyzed under the same report number (21-335-0908) and represent field conditions at Moraine Hills State Park.

The soil analysis results indicate varying soil chemistry profiles across the four sample locations, with pH levels ranging from 4.7 to 5.7, phosphorus levels between 22-38 ppm, and potassium levels between 56-121 ppm. Calcium concentrations ranged from 474-845 ppm, while magnesium levels varied from 113-224 ppm. The data includes calculated saturation percentages for cations (potassium, calcium, magnesium, hydrogen, and sodium) and nutrient exchange metrics (meq values). Estimated nitrogen release values ranged from 80-90 ppm across the samples. This soil characterization data would inform agricultural management practices and fertilizer application recommendations for the farm lease operation at Black Crown Marsh.
