Spring is officially here! If you are like me you are ready to get to work in your yard. Before you head out to one of the big box stores or your favorite nursery, head to your local UGA Extension office and pick up a soil sample bag and/or a soil probe. Fertility plays a big part in getting a beautiful showy flower or an abundance of vegetables even in a small space. Soil sampling should be done well in advance of planting or spring green-up. This allows adequate time for sample analysis, data interpretation and fertilizer and line application. Sampling depth depends on the type of plants being planted. For lawns, sample to a depth of 4 inches. For gardens, ornamentals, and mixed fruit trees, sample to a depth of 6 inches.
When and how often should soils be tested?
A: Soils can be tested any time during the year. However, allow enough time for the analysis and for fertilizer and lime application. Lime reacts slowly and, if possible, it should be mixed with the soil two to three months before planting. Generally, fall is the most desirable time to sample because landscapes and gardens are usually dry and easily accessible.
Once medium or high fertility levels are established, lawn and ornamental areas need to be sampled every two to three years.
Vegetable gardens should be sampled every 1 to 2 years.
How soon will I get my results back (turn-around-time)?
A: The analysis takes two to three working days from the time the lab receives the samples. In general, it takes 7 to 10 days from the time we receive the samples to the time you get your test reports back.
Q: Who do I contact regarding my soil test results and recommendations if I don’t understand the numbers?
A: The Soil Test Report provides an interpretation of all soil tests done by the Soil Testing Lab and is accompanied by appropriate nutrient and lime recommendations. If you need further information about your test results, contact your local University of Georgia Cooperative Extension office at 1-800-ASK-UGA1.
