Coarse-textured surface horizons are common in highly weathered southeastern US coastal plain soils. These soils have historically been managed under conventional tillage practices, but conservation tillage management practices are increasing. Although clay (<2 �m) contents are low in these surface horizons (typically <100 g kg−1), the reactive nature of this fraction tends to play a dominant r...

Pollution of soils with poiycyciic aromatic andheteroaromatic compounds (PACS) from various uses of oil products has impontant economic and toxicological implications for the polluted areas. The larger PACS are quite refractory to microbial degradation. Due to the ability of the fimgal ligninolytic enzyme systems to also degrade a range of environmental pollutants, e.g. PACS,white rot fimgihave...
