Soil chemistry testing provides analytical information about the chemical characteristics of a submitted soil sample.
Depending on the project, testing may include:
PBR Laboratories provides soil chemistry testing support from Edmonton for environmental, industrial and agricultural projects throughout Alberta, Western Canada and Canada.
The appropriate testing program should be selected around the soil matrix, project objective, suspected issue and decision the results must support.
Soil chemistry testing measures selected chemical characteristics of soil to support environmental, agricultural, industrial or reclamation decisions.
Testing can help answer questions such as:
The laboratory result should be interpreted against the relevant site or land-use context rather than treated as an isolated number.
Soil pH indicates whether the submitted sample is acidic, neutral or alkaline under the applicable analytical method.
pH can influence:
What does an unusual pH result mean?
An unexpected pH result may reflect natural soil conditions, historical site use, contamination, amendments or other local factors.
It does not by itself identify the cause.
The next step should consider:
sample location → soil type → site history → other chemistry results → project objective
Electrical conductivity provides information related to the soluble ionic content of the soil extract and is commonly used to evaluate salinity-related conditions.
When is electrical conductivity useful?
It may support:
Electrical conductivity should be interpreted together with other soil characteristics where appropriate.
Sodium adsorption ratio provides information about the relative amount of sodium compared with calcium and magnesium.
It can support evaluation of sodicity-related soil conditions.
Is salinity the same as sodicity?
No.
Salinity and sodicity are related but different soil conditions.
Electrical conductivity and sodium adsorption ratio therefore answer different analytical questions and should not be treated as interchangeable.

PBR’s existing Soil Chemical Testing page identifies major anion and cation analysis among its soil chemistry capabilities.
These measurements may support:
The required ion list should be selected according to the project objective and applicable criteria.
Total organic carbon provides information about the carbon content of the submitted soil.
Depending on the application, the result may support:
The meaning of the result depends on the soil type and project context.
Cation exchange capacity provides information related to the soil’s capacity to retain positively charged ions.
It may be useful in:
The laboratory result should be evaluated together with other relevant soil parameters.
PBR’s documented Soil Chemical Testing capabilities include total:
Testing can support soil characterization for agricultural, environmental and reclamation applications.
A nutrient result reports the amount measured in the submitted sample under the applicable analytical method.
Interpretation depends on:
PBR should provide the analytical result and practical testing guidance without implying agronomic fertilizer recommendations unless that service is separately verified.
Environmental projects may require soil chemistry to characterize baseline conditions or investigate suspected impacts.
Relevant testing may include:
What decision does testing support?
Results may contribute to:
baseline characterization → contamination investigation → remediation planning → reclamation → follow-up monitoring
The test panel should be based on site history and the potential contaminants or conditions being investigated.
PBR’s existing Soil Chemical Testing page includes petroleum hydrocarbon testing among its documented soil capabilities.
Where a site may have been affected by fuel, oil or related releases, testing can support:
A hydrocarbon result should be interpreted against the applicable criteria and sample location.
Metals may be relevant in environmental, industrial and selected agricultural investigations.
Testing may help determine whether concentrations are elevated at a particular sample location.
The result should be interpreted in the context of:
Agricultural soil chemistry testing may help characterize:
The appropriate test panel depends on the crop, soil, land-use objective and management question.
PBR should position itself as the analytical laboratory providing reliable chemistry data, while avoiding unsupported claims around agronomic recommendations.
An elevated value means the laboratory measured a result above the reference or criterion being used for that project.
It does not automatically identify:
Additional investigation may be needed.
The decision path should be:
result → applicable criterion → site context → sample location → investigation objective → next action
A laboratory result represents the submitted soil sample.
If the result will support a site-level or field-level decision, sample design matters.
Common sampling problems include:
PBR’s decision framework emphasizes representative sampling, correct containers and clear decision objectives before testing.
Ask PBR about sample requirements before collecting soil samples.
PBR Laboratories provides soil chemistry testing support from Edmonton.
PBR supports environmental, industrial and agricultural projects throughout Alberta with soil chemistry analysis and technical communication around sample requirements and testing objectives.
Clients throughout Western Canada can work with PBR for applicable soil chemistry testing related to environmental, agricultural and reclamation projects.
PBR supports Canadian organizations requiring soil chemistry data for environmental, industrial and agricultural decisions.
PBR’s goal is to help clients understand what the result means in the context of the site or soil question—not simply provide analytical numbers.
Depending on the project, soil chemistry testing may include pH, electrical conductivity, major ions, sodium adsorption ratio, total organic carbon, cation exchange capacity, nutrient-related parameters, hydrocarbons, metals and other applicable analyses.
Soil pH helps characterize whether soil is acidic or alkaline and can influence nutrient availability, metal behaviour and other soil processes.
Electrical conductivity provides information related to soluble ionic content and is commonly used in evaluating salinity-related conditions.
Sodium adsorption ratio evaluates the relative amount of sodium compared with calcium and magnesium and can support assessment of sodicity-related conditions.
No. Salinity relates to soluble salts, while sodicity relates to sodium dominance. Different analytical parameters are used to evaluate them.
Yes. PBR’s documented soil chemistry capabilities include total nitrogen, phosphorus, potassium and sulfur.
Yes. Soil chemistry can support baseline characterization, contaminated-site investigations, remediation and environmental monitoring.
Sampling should be designed around the site, depth, suspected issue and decision the results need to support. Representative sampling is important.
Yes. PBR supports projects throughout Alberta, Western Canada and Canada.
