Dataset Abstract:

Fine root biomass: Fine root dry weights from bimonthly sampling over one year at 3 soil depths (0-15, 35-50, and 85-100cm) in native forest and adjacent plantation on two soil types. Roots are separated into four classes: dead, <1mm, 1-3mm, and > 3mm diameter. Data part of the MS thesis for Marlon Menzes, Faculdade de Ciencias Agrarias do Para. Fine root nutrients: The nutrient content (N, P, K, Mg, and Ca) of fine root dry weights from bimonthly sampling over one year at 3 soil depths (0-15, 35-50, and 85-100cm) in native forest and adjacent plantation on two soil types. Roots are separated into three classes: 1-3mm, and > 3mm diameter. Data part of the MS thesis for Marlon Menzes, Faculdade de Ciencias Agrarias do Para. Litterfall:
Monthly litterfall collections over 12 month period for adjacent native forests and Eucalyptus plantations on two soil types (sand and clay). Litterfall divided into leaf, woody material, and reproductive material. N, P, K, Mg, and Ca analysis. Data used for MS thesis of Elisson Savaris, Faculdade de Ciencias Agrarias do Para. Leaf decomposition: Leaf litter was sampled from a Eucalyptus plantation and adjacent native forest and decomposition followed over one year. The study was repeated on clay and sandy soils and during the wet and dry season. Dry weight and nutrient analysis (N, P, K, Mg, and Ca) were obtained for specific sampling times during the 12 months. This study was the basis for a MS thesis for Rosience Keila de Paixao at the Faculdade de Ciencias Agrarias do Para. Twig decomposition: Small (<2.5cm diameter and 20 cm in length) and large (2.5-10cm diameter and 40cm in length) twigs were sampled from a Eucalyptus plantation and adjacent native forest and decomposition followed over one year. The study was repeated on clay and sandy soils and during the wet and dry season. Dry weight and nutrient analysis (N, P, K, Mg, and Ca)were obtained for specific sampling times during the 12 months. This study was the basis for a MS thesis for Rosience Keila de Paixao at the Faculdade de Ciencias Agrarias do Para. Contact Ken McNabb (mcnabb@auburn.edu) for additional information.
