Biosolid Residues as Soilless Media for Growing Creeping Bentgrass Sod

in HortTechnology

Two biosolid-containing waste media [composted sewage sludge (Com-Til) and incinerated biosolids (flume sand)] were evaluated as soilless media for growing `Crenshaw', `Penncross', and `ProCup' creeping bentgrass sod (Agrostis palustris). The media were combined with sand and either sphagnum peat or a commercial growing mix (Metromix) and leached with 5.1 fl oz (150 mL) tap water either zero, one or three times before seeding. Leaching with tap water to remove soluble salts had no beneficial effect on germination or dry mass accumulation. Flume sand was not a particularly good rootzone component for growing creeping bentgrass sod; however, a sieved [0.08-inch (2-mm)] medium consisting of sand, Com-Til and Metromix (8:1:1, by weight) seeded with `ProCup' creeping bentgrass at 2 lb/1000 ft2 (9.8 g·m-2) and grown over 4-mil (0.004-inch, 0.10-mm) plastic in 3.5 × 7.5 × 2-inch deep (9 × 19 × 5-cm) trays produced good sod in about 6 weeks.
