Detritus Input & Removal Treatment Project (DIRT)

Project Abstract: 
The goal of the DIRT project is to assess the role of plant litter (both from above and belowground) in controlling the accumulation and turnover of organic matter and nutrients in forest soils. This is done by systematically increasing or decreasing inputs of litter from aboveground and by either allowing or excluding tree roots from growing into permanent plots located in temperate forests.
