Agricultural Materials Laboratory

What We Do...

The Agricultural Materials Laboratory conducts analysis primarily for compliance and regulatory purposes. The samples submitted to the laboratory are submitted by the Regulatory Officers within the West Virginia Department of Agriculture; however, consumer samples are accepted to verify the quality of forage.

A diverse number of analysis are performed on animal feed (including pet food), fertilizer, forage and lime. This includes protein, crude fat, crude fiber, loss on drying (moisture), acid detergent lignon, acid detergent fiber, neutral detergent fiber, ash, dietary starch, nitrogen, soluble potash, and direct available phosphorus.

Fertilizer and lime samples are analyzed at the Charleston Laboratory. The WVDA Regulatory Officer submit official samples, and service samples can also be submitted by individuals, county extension agents, and companies. Emphasis in testing is placed on confirmation of label claims of these products. Quality control procedures within the laboratory are stringent and personnel routinely participate in proficiency sample programs (i.e. Magruder Fertilizer, and the AFPC Fertilizer programs) to assure the precision and accuracy of the laboratory’s results and the competency of the laboratory staff. The laboratory also has the capabilities of performing microscopy to check samples for adulteration or contamination

Meat chemistry is also conducted within this laboratory and all testing is performed according to the US Department of Agriculture Food Safety and Inspection (USDA FSIS) Chemistry Laboratory Guidebook. The analyses include crude protein, fat, moisture and salt.
