The Texas A&M Agrilife Extension Service Soil, Water, and Forage Testing Laboratory offers forage testing. You can print off a submittal form below, or you may pick one up from the Gillespie County Extension Office. Once you collect your sample, you will need to ship it to the laboratory for testing. There are instructions on how to collect the forage sample attached to the submittal form. For prussic acid testing, you would select the TVMDL submission form. This lab also does nitrates testing on fresh and baled hay with a faster turn around time. If you need to test your hay, our office has a hay probe available to check out from the Extension Office on a first-come-first-serve basis.
The Texas A&M Agrilife Extension Service Soil, Water, and Forage Testing Laboratory’s website has soil fertility recommendations and fertilizer calculators that you can use one you have the results. If you want to visit their website, please click here.
