This file is a soil analysis report prepared by the Illinois Department of Natural Resources (IDNR) for agricultural land at Hanover Bluff State Natural Area, a 940-acre property designated as Ag Lease Site 2565. The report documents soil sample results collected on January 13, 2023, and analyzed across multiple field locations (940-2, 940-6, 940-7, 940-8, 940-10, and 940-12) within the natural area. The data includes precise geographic coordinates for 14 soil sample locations and comprehensive laboratory analysis of soil chemistry parameters including pH levels, phosphorus, potassium, calcium, magnesium, sulfur, boron, copper, iron, manganese, zinc, sodium, and organic matter content. The samples were processed and reported on January 16, 2023, under IDNR report number 23-013-0520, providing baseline soil characterization necessary for agricultural management decisions.

The soil analysis reveals variable conditions across the sampled fields. Most samples demonstrate neutral to slightly alkaline pH levels ranging from 5.5 to 7.8, with the majority clustering between 7.0 and 7.8. Organic matter content is consistently measured between 7 and 12 percent across all samples. Macronutrient levels show substantial variability, with potassium ranging from 782 to 2539 ppm, calcium from 772 to 2487 ppm, and magnesium from 176 to 581 ppm. Field samples 8-1, 8-2, and 10-1 through 10-3 exhibit notably lower pH values (5.5 to 6.3) with corresponding buffer pH measurements, indicating potential acidity concerns requiring lime application. The data supports informed decision-making for the agricultural lease operation and provides documentation of soil conditions at the time of analysis for baseline comparison purposes.
