OMAFA accredited soil testing laboratories
OMAFAs agronomic soil laboratory accreditation program was established in 1989 to:
- Ensure accurate results, within acceptable ranges, from any of the accredited labs.
- Support the use of soil test extractants appropriate for Ontario soils and for which fertilizer response calibration data exists.
- Promote the use of OMAFA accredited labs to Ontario’s agriculture and horticulture businesses.
- Promote the use of Ontario Soil Management Committee (OSMC) approved fertilizer recommendations.
- Approve new soils laboratories that meet the performance criteria.
The accreditation program requires independent appraisal of the soil testing quality by OMAFA in coordination with the North American Proficiency Testing Program (NAPT), as well as rigorous self-evaluation by participating labs. Accreditation ensures reliability (precision and accuracy) of soil testing and a commitment to continuous quality enhancement.
As of now, there are eight tests accredited by OMAFA for soil testing in Ontario:
- pH
- buffer pH
- nitrate-nitrogen
- phosphorus
- potassium
- magnesium
- zinc (reported as Zn index)
- manganese (reported as Mn index).
The following laboratories are accredited to perform soil tests for pH, buffer pH, P, K, Mg, Mn index, Zn index and Nitrate-N on Ontario soils. For specific questions regarding the soil testing analysis or specifications, contact the appropriate company for their latest information.
