Soil pH Testing
UF/IFAS Hillsborough County Extension provides soil pH testing for $3.00 per sample. pH testing provides the pH (acidity or alkalinity) of the soil. It does not provide information about nutrients, diseases, insects or nematodes. Soil pH is important because it governs how available nutrients are to plants. Homeowners can use soil pH information to determine if existing plants are suited to a location, choose new plant material best suited to the site, and to select and apply the proper amount of fertilizer and soil amendments.
pH tests are conducted most Friday mornings, so samples should be submitted no later than close of business Thursday afternoon.
How to take a soil sample:
- Using a trowel or shovel, take 10 "slices" of soil (4-6" deep) from the area you want to test.
- Combine the slices into one sample which should equal at least 1 cup of soil.
- Spread the soil on a piece of newspaper and allow it to dry completely before bringing or mailing the sample to the Extension Office.
- Be sure to note what plants are growing in the soil to be tested e.g., vegetables, citrus, St. Augustine grass, azaleas, etc.
- Make checks payable to: Extension Overall Advisory Committee.
The results of the soil test will be mailed to you early the following week.
Other soil testing (soil fertility test, micronutrients) must be sent to the UF/IFAS Analytical Services Extension Soil Testing Laboratory in Gainesville. For information on available tests, costs, and sampling instructions, please visit this link: http://soilslab.ifas.ufl.edu/ESTL Home.asp
