SOC storage in B-horizon soils was much higher than in A-horizon soils (0.
The B-horizon soils had the highest SOC storage (0.
1999) and therefore increase EC and ESP in the B-horizon.
Such reductions in penetration resistance in the deep-ripped soils at both sites reflect greater opportunities for water transmission to depth, despite the fact that the reductions in penetration resistance caused by deep-tipping were not reflected in measurements of dry bulk density or macroporosity at the interface between and A- and B-horizons (data not shown).
The heavier texture of the B-horizon limited further infiltration and lateral subsurface flow would occur along the A/B interface, which would have allowed for continuing infiltration.
The negative relationship between B-horizon clay and the P load is interesting (Table 6); however, the heaviest B-horizons occurred at the WW1, WW3, and WAL3 sites, all of which had low to very low bioavailable (Bray) P concentrations in the top 30 mm of the soil and thus low P loss potential (Cornish et al.
As the contrast in the dielectric constant between the 2 adjacent media increases, the intensity of the reflected radar pulse would increase; thus, the character of the B-horizon affects the amplitude of the reflected signal.
However, as is discussed below, the nature of the underlying B-horizon proved to be different at G-2 to G-4.
ponding of water on top of the B-horizon, even though they did seem to exhibit the normal macromorphological characteristics.
