Sampling Instructions

If you would like your soil tested please bring in soil samples (limit of 3 at a time) taken 4-5″ deep from various parts of a bed or lawn. You will want to collect the samples of soil at the plant or lawn root zone (around 6″ deep). You should be gathering about a 1/2 cup amount from several sites within the same area to be tested. Mix them together, allow the soil to dry overnight on newspaper. Next, place 1 cup of the mix in a paper bag or clean container and label it. Collect separate samples from different areas on your property such as vegetable gardens, lawns and flower gardens. Bring all the samples to the soil testing location as listed below under “Soil Testing Dates”.

Soil Nutrient Analysis

Complete soil analysis is available through the University of Connecticut Soil Lab and the University of Massachusetts Soil & Plant Nutrient Testing Laboratory for a nominal fee. It is suggested to test soil every few years, and is particularly important when installing new garden beds or in established gardens that are not performing well.  These tests determine:
1. Nutrient levels and fertilizer recommendations;
2. Elevated lead levels or other toxic heavy metals; and
3. Proper soil amendments to avoid pollution of local waterways.
