Seed positioning in extruded pellets

Count data of emergence / survival of Jacksonia furcellata (Grey stinkwood), a native Banksia woodland shrub. Seeds were either positioned precisely at 2 mm (top), 6 mm (middle) and 12 mm (bottom) within pellets (+/- AC) or left untreated (non-enhanced) and sown under the soil surface in the equivalent positions. In two controlled trials; 1) extruded pellets sown above the soil surface and 2) extruded pellets sown below the soil surface and trays were either treated with a pre-emergent herbicide (Simazine), or left unsprayed
