  abstract = {{H}igh fertilizer input is necessary to sustain high yields in oil palm agroecosystems, but it may endanger neighboring aquatic ecosystems when excess nutrients are transported to waterways. {I}n this study, the hydrochemical dynamics of groundwater and streams under baseflow conditions were evaluated with bi-monthly measurements for 1 year on 16 watersheds. {H}ydrochemical measurements were related to the spatial distribution of soil and fertilization practices across a landscape of 100 km(2), dominated by oil palm cultivation, in {C}entral {S}umatra, {I}ndonesia. {T}he low nutrient concentrations recorded in streams throughout the landscape indicated that the mature oil palm plantations in this study did not contribute to eutrophication of aquatic ecosystems. {T}his was ascribed to high nutrient uptake by oil palm, a rational fertilizer program, and dilution of nutrient concentrations due to heavy rainfall in the study area. {S}oil type controlled dissolved inorganic {N} and total {P} fluxes, with greater losses of {N} and {P} from loamy-sand uplands than loamy lowlands. {O}rganic fertilization helped to reduce nutrient fluxes compared to mineral fertilizers. {H}owever, when {K} inputs exceeded the oil palm requirement threshold, high {K} export occurred during periods when groundwater had a short residence time. {F}or higher nutrient use efficiency in the long term, the field-scale fertilizer management should be complemented with a landscape-scale strategy of fertilizer applications that accounts for soil variability.},
