Bonduel Testing Methods

For the best use of soil testing results, it is important to know the following:

  1. Laboratory method used for each analysis.
  2. Units reported for each analysis.
  3. Any conversion or calculation used for specific tests.

Actual nutrient availability in the soil is determined by changing factors including: soil moisture, temperature, pH, clay content, internal drainage, organic contact and physical barriers. As any of these factors change, the availability will also change.
