Retracted: Comparing Throughfall And Litterfall Nutrient Fluxes In A Rubber (Hevea Brasiliensis Willd. Muell-Arg) Plantation Agro-Ecosystem At Ikenne, South-West Nigeria, Oludare H. Adedeji, Adeniyi S. Gbadegesin

Applied Environmental Research

This study compares nutrient fluxes (throughfall and litterfall) in a rubber (Hevea brasiliensisWilld. Muell-Arg) plantation agro-ecosystem at Ikenne, SW Nigeria. Throughfallsamples were collected bi-weekly under the rubber canopies (40-, 15-, and 5-year-old) using throughfall funnel collectors with 10 replicates. Litterfall was collected on a monthly basis in the three rubber stands using twenty-four 0.25 m2litter traps (eight replicates in each of the three rubber stands) positioned randomly to estimate total annual litter production (dry biomass)and its main fractions. Throughfall and litterfall samples were analyzed for total nitrogen, sodium, phosphorus, calcium, potassium and magnesium. The annual means of throughfall in the …
