| (A) Schematic representation of the microcosms used (not drawn at scale). The soil used in the experiment was a sandy loam of the White Store series and was collected from the top 30 cm of mineral horizon in the Duke Forest, Durham, North Carolina (35º 55´N, 78º 52´W), USA. (B) Detail of a plastic cylinder. (C) View of the plastic cylinders placed in each microcosm. (D) Detail of nutrient (right) and control (left) cylinders in a heterogeneous microcosm. (E) View of the microcosms in the greenhouse after two months of growth. |
