composite design/sieving (if any) |
one forest plot had the size 25.8 m x 25.8 m with 400 tree individuals planted in 1.29 m distance, at each forest plot four tree individuals of each tree species were randomly selected for sampling, at each sampling tree four soil cores were retrieved at 20-30 cm distance in each direction, all four cores form one composite sample for each sampling tree |

sample collection device or method |
metal soil corer of 6 cm diameter and 10 cm height |
sample material processing |
removal of roots and stones,sieving 2 mm mesh, homogenization of 4 soil cores collected around one sampling tree, snap-freezing of about 15g soil in liquid nitrogen, transport on dry ice and storage at -80�C, freeze-drying before transport and relocation to -80�C upon arrival four days later |
