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 (is) 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 mini;
0.63 0.34 cm mini; 113.07 +39.37 cm) than for Tilton's Run (1.76 1.42 cm min~; 0.40 +0.18
cm mini; 73.68 25.94 cm), and lowest for Cumberland (0.63 +0.34 cm mini; 0.27 0.19 cm
mini; 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)
