Explanation of Soil Test Report Form

Soil testing services are available through the St. Charles County Extension Center to help provide guidance for applying the correct amount of fertilizer and lime to lawn and garden soils. The fee for testing is $10.00 and requires about 2 cups of soil (please air dry first).

The information on this page also explains the results that are provided on the soil test report from the University of Missouri Extension Soil Testing Lab. Should you have questions on any soil test report you have received, please feel free to contact us at the University of Missouri Extension Center of St. Charles County. (636-970-3000)

The Soil should be tested every two to three years to determine the effects of your fertilization practices and to develop a new set of fertilizer and limestone guidelines.


Explanation
of Soil Test Report Form

one-a.gif (924 bytes) "Sample ID" (such as for a lawn or garden) This is information you provided upon submitting your soil sample. The fertilizer suggestions are based on this, so be sure it is correct. [back to form]

two-a.gif (943 bytes) "Ratings" indicates how high or low your soil is considered in each category. [back to form]

three-a.gif (946 bytes) "pHs" indicates how acid or alkaline your soil is considered. Most lawns like a pHs of around 6.5, but grow well from pHs 6.0 to 7.0. Vegetables and flowers grow best from 6.5 to 7.5, but there are wide ranges of tolerance. [back to form]

four-a.gif (935 bytes) "Phosphorus, potassium, calcium, and magnesium" are listed on the next four lines and show the level of nutrients in your soil in pounds per acre (a historical convention from when soil tests were primarily for commercial growers). The numbers have little meaning for most homeowners. The ratings, however, indicate if these nutrients are considered low or high for your soil. [back to form]

five-a.gif (941 bytes) "Organic Matter" is the percent of organic matter found in your sample. As it decays organic matter provides nutrients and humus, which helps soil hold nutrients and water. Organic matter levels between 1% and 3% are fine for lawns, but 4% to 6 % is better for vegetables or flowers. The rest of the information on this line means little to you, but is used by the soil lab to determine factors about your soil. [back to form]

six-a.gif (953 bytes) "Fertilizer and Limestone Suggestions" indicates how much nitrogen, phosphate, potash (potassium), and lime your soil needs. This is the most important part of the report for home gardeners. The rates are in pounds needed per 1000 square feet. See the back of this page for more information about fertilizers and how to apply them. [back to form]

seven-a.gif (927 bytes) The soil test finishes with notes about the soil test in general, and below the dashed line, notes with specific recommendations for your soil.[back to form]
