The pedons exhibited differences in sequence of horizons; whereas Pedon A6 consisted of only one genetic soil horizon (Ap), the others consisted of 3-4 horizons (Table 2).
It seems that both processes of tillage and water erosion participated in reduction of pedon. Measurements of deposited soil material showed that a majority of the eroded soil was maintained within the study area.
Based in Northern Italy, Pedon employs 750 people worldwide in seven factories, with a focus on five business areas including dried pulses and grains, dessert ingredients and dried mushrooms.
Saturated hydraulic conductivity was estimated by measured and qualitative means for each representative soil pedon. A Compact Constant Head Permeameter (CCHP; and also known as an Amoozemeter; KSAT Inc., North Carolina) was employed to measure [K.sub.sat] via constant-head well permeameter techniques detailed in Amoozegar (1989).
Two C and N samples were analyzed for each depth increment in each pedon. The Sharpsburg soils sampled for this study have been leached free of carbonates (pH is about 6.0) (30); therefore total carbon is assumed to also represent total soil organic carbon (SOC).
The traits of a pedon are set by the combination of factors that formed it.
Soils were classified to the subgroup level using information about texture, pH, horizons present, depth to bedrock, color and pedon structure, shape and size.
Photographs of dye-stained soil profiles together with field measurements of soil physical properties and root distribution were used to measure and understand preferential flow at the pedon scale.
