The US Composting Council (USCC) and the American Society of Landscape Architects (ASLA) are excited to be sharing a new partnership focused on #compost, #soils and #climatechange solutions.

To launch and promote a better understanding of compost and compost uses Landscape Architects should join us Wednesday, October 18th from 2-3pm EST for a webinar.

In this webinar, USCC staff and a panel of industry experts will delve into the historical origins of Test Methods for the Evaluation of Compost & Composting (TMECC), the Seal of Testing Assurance (STA) program, and the foundational research driving their development. The presenters will shed light on the Compost Analysis Proficiency (CAP) Program, tasked with overseeing the quality of participating laboratories. Furthermore, they will furnish practical, real-world examples of compost end-use specifications, illustrating its efficacy in enhancing soils within their natural context by adhering to these well-established standards. Lastly, a comprehensive review will be provided on the methods and terminology employed when specifying the application of compost for on-site soil improvement.

Learning Objectives:

  • Comprehend the rationale behind the creation of the STA Program and the effectiveness of the labs that participate in it, which represents the development of a national testing initiative.
  • Gain proficiency in the interpretation of compost testing data, as presented on a STA Compost Technical Data Sheet (CTDS).
