Abstract: Techniques for managing roadways often incorporate use of sodium chloride, or roadsalt. Use of this substance can vary greatly depending on whether state or local municipalities are prescribing management for particular roadways. Roadsalt has the potential to affect the chemical composition of roadside soils. This study sought examine relationships between winter management techniques and soil chemical properties as distance increased from roadsides. Transects were set up perpendicular to 5 roads managed by the State of New York, and 5 roads managed by towns in Franklin County, New York. 10 samples were removed from the soil surface at each transect, every two meters back from each roadside from 2 to 20 meters. pH, conductivity, abundances of Ca, Na, K, Mg, Cl, % Na on CEC, & % Ca on CEC were determined for each sample. Using ANOVA equations pH, % Na, and Cl concentration were found to have significant relationship with distance while %Na, % Ca, and Na concentration had significant relationships with regards to management. It was concluded that Na is displacing large amounts of Ca on exchange near state managed roads, decreasing soil fertility specifically in those areas. Results follow trends found in other studies that cite increasing concentrations of both Na and Cl on watershed scales.
