On this webpage you can find copies of soil maps showing the estimated concentrations (mg/Kg) of base cations, extractable P, and ammonium and nitrate for the BCI 50 ha Forest Dynamics Plot. Kriged estimates for the 20 x 20 m quadrats are available in this excel file. A copy of the protocol used for the sampling of the plot, collection and chemical analysis of soil samples is available here.
