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:
- Laboratory method used for each analysis.
- Units reported for each analysis.
- 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.
