The Texas A&M Agrilife Extension Service Soil, Water, and Forage Testing Laboratory offers soil testing. You can print off a submittal form below, or you may pick one up from the Gillespie County Extension Office. We have soil sample bags at the Extension Office that you may use to submit your samples to the laboratory. Once you collect your sample, you will need to ship it to the laboratory for testing. There are instructions on how to collect the soil sample attached to the submittal form. We also have a soil 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.
