Effects of slash management on tree growth and nutrient cycling in second-rotation Eucalyptus replanted sites in the Congo
Since 1998 an experiment has been conducted in the Congo to evaluate harvesting methods with respect to sustainable management of eucalypt plantations. The results showed: (1) a marked negative effect on tree and stand growth when all slash materials were removed; (2) a risk of nutrient teaching after harvesting due to the high rate of decomposition of organic residues; (3) a production of inorganic nitrogen in the surface soil layer which depends on slash management; and (4) a high rate of nitrification and a risk of N tosses in the early stage of stand development.
