    Nutrient cycle in TRF:

    -rapid and continuous

    -high annual turnovers

    a) Biomass:

    -hot and wet climate

    -lush vegetation growth

    -huge storage of nutrients

    -store mainly in vegetation

    -uptake lots of nutrients from soil due to lush vegetation

    -transfer little nutrients to litter by leaf fall because trees are evergreen

    b) Litter:

    -hot and wet climate

    -rapid decomposition and leaching

    -low nutrient storage

    -little surface litter accumulation

    -receive many nutrients from rainfall and leaf fall due to heavy rainfall

    -little nutrients loss by runoff due to high infiltration rate

    -transfer many nutrients to soil by decomposition

    c) Soil:

    -intense and prolonged weathering +active leaching

    -base are totally removed

    -hot and wet climate speed up nutrient transfer

    -low storage capacity for nutrients

    -receive many nutrients from weathering and decomposition

    -much nutrient loss by leaching and uptake by plants
