Abstract EN
Leaf litters of jarrah (Eucalyptus marginata Donn ex Sm.) and banksia (Banksia menziesii R.
Br.) were decomposed at woodland and wetland conditions for two years to test site influence on the rates of decomposition.
Weight loss was rapid in early rains but slowed substantially in the following months, resulting in 2/3 to 1/2 weights remaining after two years of field exposure.
Litter weight loss was well described by a two-substrate quality decay model (R2=0.97−0.99), and the half-lives were 2.6–3.2 weeks (labile fraction) and 6.4–6.9 years (recalcitrant fraction) for jarrah, and 1.0–1.7 weeks (labile) and 6.6–9.9 years (recalcitrant) for banksia.
The nutrient mobility was K≈Mg≈S>Ca>P, and the losses of K, Mg and S were correlated with the weight loss of litter (R2=0.77−0.94, P<0.03).
P mass increased by 129% in jarrah litter and 174% in banksia litter in the woodland site, suggesting woodland with tree cover provided a better habitat for microbial biomass than non-inundated wetland, hence a notable P conservation in the decomposing litter.
