Types of samples:
P = Ground vegetation, sampled with a 30*30cm frame
LF = OL+OF material, sampled with a 30*30cm frame
H  = OH material, sampled with a 30*30cm frame
0_5  = mineral soil 0-5cm depth, sampled with soil corer (68 mm diameter) 
5_10  = mineral soil 5-10cm depth, sampled with soil corer (68 mm diameter)
10_30  = mineral soil 10-30cm depth, sampled with soil corer (68 mm diameter) 
30_70  = mineral soil 10-70cm depth, sampled with soil corer (68 mm diameter) 
H2 = OH material, sampled with soil corer (68 mm diameter), material wasn´t identified in the field as OH, it was seperated in the laboratory from the mineral soil sample
FFLRM = Forest floor litter raking material, sampled at a 1m² area
ROM = Remaining organic material (after forest floor litter raking), sampled with a 30*30cm frame
Litterfall = Litter fall, sampled at a area of 0.173 m²
