Bonduel Testing Methods

Certifications

Our agricultural testing lab in Bonduel routinely evaluates its performance with internal and external proficiency certification programs, and holds the following industry certifications:

  • Soil Science Society of America (NAPT-PAP)
  • Agricultural Laboratory Proficiency Program (ALP)
  • Manure Analysis Proficuency (MAP)
  • Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP)

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.
