Fine Root Responses To Soil Decompaction And Amendment In Red Maple (Acer Rubrum), John Mcintyre
All Theses
A combination treatment (AFM), designed to decompact and amend urban soils, and its individual components (air tillage, fertilizer, and mulch) were tested to determine their effects on fine root morphology. The site was an urban area located in Anderson, SC and included 50 red maples (Acer rubrum) growing in compacted, nutrient poor soils. Treatments were installed in November 2005, and data was collected through summer 2008. Data collection included minirhizotron images, soil moisture readings, soil temperature readings, and pre-dawn leaf water potentials. The AFM treatment had the lowest root production, root standing crop, and median root lifespan. The AFM treatment …
