How accurate are the soil test results?
The soil testing laboratories do a good job of determining the salt pH and nutrient content of the soil sample you submitted. The University of Missouri has two soil testing labs, one in Columbia on the University campus and the other in Portageville at the University Delta Center. To ensure accuracy, check samples are continually run with samples submitted by you. Also, the University lab exchanges samples with several private labs to assure accurate results from all labs involved. Even though the tests are accurate, the results are only as good as the sample you submit. Well taken soil samples yield good results while poorly taken samples yield poor results. How do I get a good soil sample? Most problems with unreliable test results are due to improper sampling. In general, you should take at least 10 to 15 soil cores per soil sample per field.
