Soil Testing

Many customers come to our office with questions about their lawn, garden, trees, etc., and we always recommend beginning with a soil test. That's because under all, it is the soil that carries nutrients to plants. Therefore, with a proper soil analysis we can make evidence-based recommendations that are specific to your situation. Here is a link that will show you how to collect your soil sample:  Soil test sampling instructions.

It is not necessary to come by and pick up the bags first. Bring your dry sample in a ziplock bag, cup, or any container, and we will transfer it to a UGA soil bag before shipping. We will need at least 1 cup of dry soil. One sample is sufficient for each lawn. The cost per sample for the basic soil test is $8.00 (cash, check or credit card) and results can either be mailed or emailed. It usually takes about 10 to 12 days to receive your results.

Here is a tip to help dry your soil quicker: Place your wet soil in a shallow pan and place on the dashboard of your vehicle with the windows rolled up in the sunshine. It will dry it out quickly.

Water Testing

Water testing is important for monitoring water quality for people who get their water from a well.

When you pour yourself a glass of water to drink, it may appear clean, taste good and you may expect it to be safe. However, many sources of water we assume are safe can contain dissolved minerals, organic compounds or even live organisms at harmful concentrations. Contaminated water used for drinking and cooking may affect your health. Also, high concentrations of certain minerals in your water can result in quality issues such as unpleasant taste and odors or staining of bathroom fixtures and/or laundry.

The quality and safety of drinking water is of great concern to many Americans today because of an increased interest in health and environmental quality. This focus on water quality has led many Americans to consider testing their water.

To have your water tested, please bring in about 8 oz of the water. The cost per sample for the basic water test is $22.00 (cash, check or credit card) and results can either be mailed or emailed. It usually takes about 10 to 12 days to receive your results.
