| Abstract | Effect of the practices of forest establishment on the soil organic carbon and soil aggregate stability in the North-East of Argentina This study evaluated the behaviour of organic carbon, labile carbon and aggregate stability under different residue management systems after harvesting of Pinus elliottii E. at the beginning of the second rotation. After 3 years and 5 month of applied the treatment was compared the following systems of site preparation: 1) extraction of forest residues, 2) burning and tillage, and 3) conservation of residues on the soil. The extraction of residues, and burns with disk caused a fall in the organic carbon soil OC of the 20% and 37% in the 0-5 cm and 5-15 cm layer. The loss of light carbon was of the 35% in surface and of the 50% in subsurface. The aggregate mean weight diameter wet sieving was affected by residue extraction. The smaller aggregates were found following the application of burning and tillage practices. The change in aggregate diameter indicated a marked process of loss of the structure associated with the decrease of the organic carbon and with the light carbon to apply intensive practices of site. |
