We test several human pathogens on produce and water samples.  All of our procedures are AOAC approved methods.  Positives on produce are confirmed with DNA analysis.

What is Nitrogen Mineralization?  It is the measurement of the nitrogen from the organic matter that will be released during the growing season?

We offer grid testing for fertility, nematodes and diseases on most crops.  Grid samples are done on 0.25 to 2.5 acre grids.  Grid size depends on the crop and tests required.  We have a collecting crew available and can make your maps and shapefiles for your VRT equipment

The lab runs 24 hours a day during the summer months.  Our database includes 220 crops for recommendations.  We offer monitoring programs where the crop is checked weekly for soil and plant nutrients.  We also offer a one-time Commercial Plant Test.

Our water analysis includes salts, major and minor nutrients, alkalinity, water hardness and pathogens such as coliform bacteria and E. coli.  This test is to measure the quality of your irrigation water.


Since August 1st, 2014 we have been able to test alfalfa hay for the presence of the Roundup Ready Alfalfa. In our test trials we are able to detect 0.1 percent GMO alfalfa in Non-GMO material.  With this new test we can maintain a 24-hour turn around and give you the results at the same time as our Verticillium albo-atrum assays.​

Our soil testing Lab has 24 to 48 hour turn around time.  With six weighings, we specialize in problem soils and our reports come with recommendations based on your crop.  Our most popular soil tests are Agriculture, Garden, City Parks, Golf Courses (including turf and lawn), Dryland Wheat , Giant Pumpkin and Grid sampling

We offer complete nematode testing including cyst nematodes.  Root knot nematodes and cyst nematodes are separated by species.  Nematode results are generally published within 48 hours after receiving the sample.

Western Laboratories has been involved with the Atlantic giant pumpkin growers for several years and we have been instrumental​ in the helping pumpkin growers to break the records. We help the pumpkin growers to better understand soil and diseases reports.

Our feed testing is all wet chemisty.  For dairy feed testing we recommend our test #31 which includes a calcium to phosphorus ratio.  We also offer nitrate testing with guidelines.

We offer plant disease testing for most common crops including but not limited to potatoes, onions, gardens and giant pumpkins.  We test for soil born diseases including pink root (onions), verticillium, rhizoctonia (to AG-level), fusarium and pink rot (potatoes). Plant diseases are broken down to species level with DNA analysis .

Testing includes manure (wet or dry), compost, lagoon and holding ponds.  This test explains pounds of nutrients per ton of dry manure and pounds of nutrients per 1,000 gallons of lagoon/slurry water.  We can test fertilizers for % of nutrient available in product.
