Effects of different sidewalk designs on soil characteristics and on the growth and physiology of shade tree species

2013 | Dr. Alessio Fini, University of Florence
The project is aimed at comparing four different profile designs for parkings lots, sidewalk, and other paved areas. Treatments compared are: A) impervious pavement (asphalt on concrete sub-base); B) pervious (curb on crushed stone sub-base); C) permeable (resin bound pavement on crushed stone sub-base); D) unpaved. In 2011, an experimental plot with these treatments (and 6 replicate) was built in Vertemate con Minoprio (CO, Italy). Two urban tree species (Fraxinus ornus and Celtis australis) were planted in a 1 x 1 m planting pit, in the differently paved subplots in spring 2012.
The project is then aimed at evaluating the effects of different profile designs and soil cover on:
• Soil temperature, which will be measured at 25-30 cm below grade, where most of roots are located
• Soil moisture (v/v), which will be measured at 25 cm (5 cm below the sub-base) and at 45 cm below grade, in order to describe how moisture varies at different depths within the rootzone
• Soil O2 content and CO2 efflux from soil
• Leaf gas exchange (photosynthesis, transpiration, water use efficiency), water relations (pre-dawn water potential) and growth of trees planted in pits surrounded by the different materials
• Air temperature and humidity in the different plots

Thanks to the TREE Fund, I am able to obtain a quality education and focus on my studies instead of on tuition bills. I greatly appreciate the support and reassurance I have received, knowing that there are professionals in the industry who care and support my education and success at Kansas State University. Thank you!
