Woody biomass residue retention effects on soil quality indicators in the Lower Coastal Plain of Georgia and North Carolina
MetadataShow full item record
Levels of woody biomass retention (no retention guidelines- all operationally accessible residue removal, 15 or 30% retention, or no residue harvest) and the post-harvest redistribution of these materials (distributed or clustered) were evaluated for impacts on soil quality indicators in Georgia and North Carolina. Overall, the treatment effects on soil C and N were minimal. However, soil compaction increased following harvesting and site-preparation. Windrow or pile size after site preparation did not significantly affect the soil organic carbon, soil organic nitrogen or soil extractable macro-nutrients (Ca, Mg, PO4-P, K). In the case of ion-exchange resin recoverable macronutrients, no elements were affected by pile size but K did decrease with distance from windrows. In general, in the first year after harvest, woody residue retention levels had few impacts on measured soil attributes.
