The Substance of Soil

Soil is the basis of survival. Without soil, humans and most other living beings could not exist. Conor Guidarelli, who has dug deep into the soils of the Arnold Arboretum will present an overview of soil, from its formation and components to its properties. He will discuss ways to analyze soil quality and health to determine whether or not amendments are needed based on the soil outcome/use desired. Participants are encouraged to bring a pint glass jar with about a cup of soil in it to class.
