Abstract
Information is needed on microclimatic differences present in different landscapes such as openpasture versus silvopasture in the Southeast USA This research tested a hypothesis that microclimatic conditions in maturepine silvopasture would be milder compared to openpasture The research objective was to quantify microclimatic differences between maturepine silvopasture and open pasture The research was conducted in a loblollypine Pinus taeda Lbahiagrass Paspalum notatum Flugge silvopasture and an open bahiagrass pasture 5ha each in Chipley Florida Microclimatic parameters air temperature soil temperature at 5 and 10cm depths wind speed gust speed wind direction humidity dew point rainfall soilmoisture content total solar radiation and photosynthetically active radiation were collected from November 2005 to January 2008 using HOBO© weather stations located in each pasture type Data were analyzed to determine overall as well as seasonal monthly and diurnal differences between pasture types Evapotranspiration was calculated from air temperature wind speed relative humidity and total solar radiation The overall average values for all microclimatic parameters were lower in silvopasture compared to openpasture Seasonal monthly and diurnal differences between pasture types were also detected for several parameters These results indicate that milder microclimatic conditions occur in silvopasture versus openpasture on the Coastal Plain of the Southeast USAThe authors acknowledge the generous cooperation of Mr George Owens Owens’ Farm Chipley Florida for access to his property for location of weather stations and the Southern Sustainable Agriculture Research and Education Program SSARE for financial support
