Soil properties and processes were evaluated on three types of colonial agricultural land-use - plowing, pasturing, and selective tree removal in a woodlot that ceased in the mid to late 1800s. Plowing, the most intensive type of agricultural disturbance, mixes soil to a depth of approximately 15cm, homogenizing the soil resources and likely reducing diversity in microenvironments. Removing trees and replacing them with grasses for pasture decreases the organic matter amount and types of inputs to the system, decreasing resource diversity. Woodlots, altered by selective and chronic tree removal, would have more limited decreases in resources and microenvironments. This study examined soil surface (at 10cm above the soil surface) CO2 concentrations and soil respiration at the land use sites. Soil respiration and surface CO2 concentrations were highest in the woodlot sites and lowest in the formerly plowed sites.

Intersection points within the 5m x5m grid were used as loci for measurements of soil surface CO2 concentrations and soil respiration. Concentrations and soil respiration were measured weekly from July 1997 through October 1997 using a Li-Cor 6200 gas analyzer and Li-Cor 6250 IRGA chamberhead. Concentrations were determined at 10cm above the soil surface; fluxes were measured using 10cm PVC rings that were inserted 2cm into the forest floor and were left affixed to the soil during the entire measurement period. Soil temperature (upper 5 cm of forest floor) and air temperature (at 10 cm above the soil) were measured concurrently with concentration measurements; soil temperature was measured concurrently with respiration measurements.
