Armed with a specialization in bioelectromagnetics, Thomas Dykstra introduces the concept of electrical conductivity (EC) in the soil as it relates to plants and microbes. Back again by request, Dykstra discusses techniques for balancing EC, having enough conductivity for maximum plant growth but not so much that plant growth is compromised. Dykstra covers the tools needed to quickly measure EC on your farm, along with practical references outlining the impact of EC in your no-tilled soils.

You’ll Learn: How EC impacts soil health and nutrient availability & the EC conditions that some crops — & weeds — prefer to grow in.
