Litterfall production and litter decomposition experiments: in-situ datasets of nutrient fluxes in two Bornean lowland rain forests associated with Acacia invasion

This dataset contains the original data from which the figures and tables for the article "Differential impacts of Acacia invasion on nutrient fluxes in two distinct Bornean lowland tropical rain forests" were prepared. It documents parameters relevant to nutrient fluxes via litterfall production and leaf litter decomposition rates from 2016 to 2017 in two selected lowland rainforests in Brunei Darussalam that are associated with Acacia invasion. Both litterfall sample collection and litter decomposition bag experiments followed standard protocols. Leaf litterfall fractions from the litterfall production experiment were analysed for nutrient contents of nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg), and calcium (Ca). Nutrient addition and nutrient use efficiency values were calculated based on nutrient concentration and monthly leaf litterfall production in the different habitat types studied. The mean percentage of litter mass remaining, K day^-1, K year^-1, half-life t_0.5, pH values, and nutrient concentrations (N, P, K, Mg, Ca) were calculated for leaf litter samples collected after 336 days in the different habitats.
