The presentation introduces the use of biological stimulants in soil.  Motivation to use the diverse portfolio of products available based on market demand is reviewed and along with a few examples of how these projects are intended to work.  Although interest in this field is strong, on farm results are highly variable including negative responses.  In addition to the use of biological stimulants, the use of biochar applied to soil is introduced. The properties of biochar are reviewed along with a discussion about when it is appropriate to use biochar as a soil amendment.
