| Abstract/Contents: | "In an effort to generate more information on the use of biosolids in the turf industry, a study was conducted to compare the effectiveness of biosolids with recommended organic sources in enhancing soil microbial populations and N availability in putting green sand rootzones. The treatments included four types of rootzones as follows: sand (control), sand mixed with Dakota reed-sedge peat (10%, v/v), sand mixed with yard-waste compost (10%, v/v), and sand mixed with biosolids (10%, v/v), which were established at the North Shore Country Club golf course, Glenview, IL, USA in 1997. All plots received the same fertilizers mainly in organic forms at 100 kg N ha-1 year-1. Creeping bentgrass (Agrostis palustris) turf was established, and was managed as a practice putting green. Soil microbial biomass in the rootzone (0-30 cm) was higher either under compost (fall 2004 and summer 2005) or biosolids (summer 2003) than other treatments. Rootzone ammonium oxidizer populations were higher with biosolids (5400 g-1 soil) than peat (1200 g-1 soil) and compost (500 g-1 soil) amendment and in control (400 g-1 soil) in summer 2003. The nitrite oxidizer populations were higher with biosolids (24000 g-1 soil) than compost (8300 g-1 soil) and peat (4700 g-1 soil) amendment and in control (3700 g-1 soil) in summer 2005. Soil potentially mineralizable N, also being lowest in control, was higher in the biosolids-amended than compost- and peat-amended rootzones. In most seasons, the nitrate concentrations in biosolids rootzone (3.16-19.3 mg kg-1) were higher than in compost (2.79-17.7 mg kg-1), peat (1.83-14.4 mg kg-1), and control rootzone (0.81-15.2 mg kg-1). The study indicates that while compost could restore soil microbial biomass better than peat, biosolids could maintain greater N supply than peat and compost." |
