Located inside the Exhibits Center in 4H Hall. We will test soil samples taken from your garden for proper pH and make recommendations how to correct low or high pH. Please bring no more than 6 samples for testing. Use plastic baggies with about 1/2 cup of your soil. Mark each bag with the location from which it was collected. Since we need an hour to do the testing please get your soil samples to the “testers” one hour before the days quitting time. Our hours are Saturday 9 – 4 and Sunday 9 – 3.
