Compost Science and Engineered Soils

Start Date
End Date
Starting with a tour of an active commercial composting facility we will provide a first hand experience and understanding of compost and how it is made.
We will cover all aspects of manufacturing compost starting with the fundamentals of compost science digging deep into the biological and chemical elements. With this base of knowledge we will then discuss raw feedstock materials, compost recipes, compost processing, storage and handling.
Following the tour we will cover Engineered Soils in greater detail. Engineered soils not only provide the growing medium for aesthetically pleasing landscapes but also play critical roles in stormwater management, reduction of irrigation requirements, mitigating heat island effects and in certain cases provide thermodynamic insulation properties. The implementation of engineered soils is a rapidly evolving practice, and as such, the current state of specifications in the field are divergent and constantly advancing. This course will provide perspective on what constitutes a quality engineered soil, how it is made, how it works, as well as recommendations for writing the most effective specifications.
