Why Test Soil?
Over 200,000 soil samples are analyzed in Wisconsin each year, and the results of these tests guide Wisconsin farmers in the use of lime and nutrient applications. The appropriate use of lime, fertilizer, manure and other nutrient sources significantly increases Wisconsin farm income. Just as importantly, following nutrient application guidelines prevents over-application of nutrients. This, in turn, enhances profitability and reduces the potential for environmental degradation.
Analysis & Reporting
Your soil test report will provide an accurate index of the level of available nutrients in the soil; indicate the degree of nutrient deficiency that may exist for the various crops grown; suggest how the deficiency might be corrected; and provide the results in a meaningful way so that you can make the appropriate decision as to what nutrients to add.
Laboratory analysis will include soil pH, percent organic matter, phosphorus and potassium. Additional secondary and micro-nutrient analysis of calcium, magnesium, boron, manganese, zinc and sulfur are also available for an additional charge.
Your report is also available in PDF format accompanied by a spreadsheet containing the laboratory results and a SNAP-Plus compatible input file.
