The Compost Conundrum: Selecting the Right Amendment

Many questions enter into the compost purchase decision, such as: What is the source material? What contaminants might be present? How does one read the test information on C:N ratio, salts, microbes and metals? How will regulations such as AB 1826 organic waste recycling affect compost supply quality and quantity? and How much compost should you apply and when?  This webinar will answer these questions and address other topics, such as how to report compost applications to the Regional Water Board, what to ask when searching for a supplier, and lessons learned from those who have made poor choices. In addition to giving you the information you need to make an informed compost purchase decision, this session will cover basics such as why compost receives greenhouse gas credit in the Healthy Soils Program and future carbon credit programs, and generally how to build your soil health. A live Q&A follows the presentation.
