Accelerated rates of formation of the petrocalcic horizons occurred when extrinsic (pulses of loess deposition) and intrinsic (engulfment of burrowed horizons) thresholds were exceeded.

Stratigraphic evidence suggests that the soil formation that accompanied the rise in the land surface due to additional loess deposition may have occurred during the late Wisconsin glaciation when giant glacial outburst floods in the channeled Scabland triggered a new cycle of loess deposition.

Sequence stratigraphic analysis reveals 32 seismic sequences developed by 30 glaciation during last 2.8 m.y.

Facies analysis describes different kinds of sedimentary environments that was active during deposition of Naust Formation.

During late Neogene a thick succession of Naust Formation prograded westward.

Yet, an equilibrium profile must be anchored at both ends.

Concurrently, a nodal avulsion site developed at 55 km inland, creating avulsions by-annexation.

Geomorphic evidence suggests movement along a normal listric fault occurred in proximity to the nodal avulsion site.

Differences in soil organic carbon, nitrogen and carbohydrates as a result of different tillage practices under continuous cropping were studied in a 12 year old sorghum/rye rotation experiment in the Georgia piedmont.

Soil organic C and N concentrations in an aggrading agroecosystem (no-tillage, NT) were significantly higher than in a degrading agroecosystem (conventional tillage, CT) at all dates.
