Evaluate the effectiveness of the microclimate modified by agroforestry practices on production efficiency a silvopasture system.
The project involves comparison of the water and light use efficiency of forages grown under the shade of widely-spaced trees (silvopasture) and in a conventional pasture in Fayetteville, Arkansas. The research approach utilizes surface energy balance methods to quantify differences in evapotranspiration and microclimate between forage grown beneath rows of five tree species and in the open. Forage height, biomass, and leaf area index will be measured before each grazing event. Forage produced and cumulative water use from the onset of growth or since the last grazing event will be used to calculate water use efficiency.
