Soil health plays a critical role in both the quality and quantity of the food we produce. Unfortunately, many of us are faced with the reality of toxins in our soil, which limit our soil’s health and expose gardeners and consumers to risk. In this Sunday, March 27 workshop, beginning at 2 pm at the Codman Community Farms, 58 Codman Road in Lincoln,Â you will learn about the possible contaminants gardeners face (from lead to residual herbicides and pesticides) and how to accurately test soil to assess potential risks. Instructor Derek Christianson (below) will then go over strategies on how to exclude, mitigate, and/or remediate compromised soils. Underlying his conversation will be discussions and hands-on activity designed to help you understand the basics of soil chemistry and build an understanding of soil amendments used to correct mineral deficiencies in our soils. Cost: $30.Â Derek Christianson is a farmer and community educator at Brix Bounty Farm in Dartmouth, MA (www.brixbounty.com).
