Carbon Sequestration in Reclaimed Mined Soils of Ohio

PDF Version Also Available for Download.

Description

This research project is aimed at assessing the soil organic carbon (SOC) sequestration potential of reclaimed minesoils (RMS). The experimental sites, owned and maintained by the American Electrical Power, are located in Guernsey, Morgan, Noble, and Muskingum Counties of Ohio. These sites, characterized by age chronosequences, were reclaimed with and without topsoil application and are under continuous grass or forest cover. Among the three sites chosen for this study one was reclaimed in 1978 (Cumberland), one in 1987 (Switch Grass) and one site was reclaimed in 1994 (Tilton's Run). All three sites were reclaimed with topsoil application and were under ... continued below

Description

This research project is aimed at assessing the soil organic carbon (SOC) sequestration potential of reclaimed minesoils (RMS). The experimental sites, owned and maintained by the American Electrical Power, are located in Guernsey, Morgan, Noble, and Muskingum Counties of Ohio. These sites, characterized by age chronosequences, were reclaimed with and without topsoil application and are under continuous grass or forest cover. Among the three sites chosen for this study one was reclaimed in 1978 (Cumberland), one in 1987 (Switch Grass) and one site was reclaimed in 1994 (Tilton's Run). All three sites were reclaimed with topsoil application and were under continuous grass cover. Eighteen experimental plots were developed on each site. Five fertilization treatments were applied in triplicate on each experimental site. During this quarter, water infiltration tests were performed on the soil surface in the experimental plots. Soil samples were analyzed for soil moisture characteristics. This report presents the data on infiltration rates, volume of transport and storage pores, and available water capacity (AWC) of soil. The infiltration rates after 5 min (i{sub 5}) showed high statistical variability (CV > 0.62) among the three sites. Both steady state infiltration rate and cumulative infiltration showed moderate to high variability (CV > 0.35). The mean values for the infiltration rate after 5 min, steady state infiltration rate, and cumulative infiltration were higher for Switch Grass (2.93 {+-} 2.05 cm min{sup -1}; 0.63 {+-} 0.34 cm min{sup -1}; 113.07 {+-} 39.37 cm) than for Tilton's Run (1.76 {+-} 1.42 cm min{sup -1}; 0.40 {+-} 0.18 cm min{sup -1}; 73.68 {+-} 25.94 cm), and lowest for Cumberland (0.63 {+-} 0.34 cm min{sup -1}; 0.27 {+-} 0.19 cm min{sup -1}; 57.89 {+-} 31.00 cm). The AWC for 0-15 cm soil was highest at Tilton's Run (4.21 {+-} 1.75 cm) followed by Cumberland (3.83 {+-} 0.77 cm) and Switch Grass (3.31 {+-} 0.10 cm). In 15-30 cm depth Switch Grass had higher AWC (3.15 {+-} 0.70 cm) than Tilton's Run (3.00 {+-} 0.43 cm) and Cumberland (2.78 {+-} 0.34 cm). In 30-50 cm depth Tilton's Run had higher AWC (4.31 {+-} 1.25 cm) than Switch Grass (3.18 {+-} 0.70 cm) and Cumberland (2.95 {+-} 1.07 cm). The volumes of transport and storage pores were fairly similar among sites up to 30 cm depth, but were variable for 30-50 cm depth. These preliminary results along with those reported earlier for the third quarter suggest that the management effects are important and indicative of these sources of variability.
