The Soil Test Results sheet
that you receive from the LSU AgCenter Soil Testing and Plant Analysis Laboratory
may not be easily understood if this is the first time you have submitted a soil sample. The values on that page that are to the right of the nutrient or elemental name are numbers that were found after testing the soil with a particular method or test. The numbers are important; however, the ratings are most important. These are a range of values within each rating. Thus, if your soil test value for a nutrient falls within that range, then that rating will be found on the Soil Test Results sheet just to the right of the value for that nutrient.
Soil test recommendations are given on the lower half of the Soil Test Results sheet. The recommendations are given as ounces or pounds of a fertilizer form on the basis of per bush, per foot of row, per 100 or 1,000 square feet or per acre.
