| Abstract/Contents: | "Creeping bentgrass turf responded during grow-in to varying rootzone mixes in a study conducted at Rutgers University. Among the study's findings: The most consistent and best performing turf over the first year of establishment was observed and organic amended plots at higher amendment rates including 20% compost, 20% sphagnum peat, 10% reed sedge peat and 20% Irish peat mixes; these mixes had capillary porosity greater than 25% which exceeds the USGA upper limit. The 20% loam had water retention capacity similar to the 20% sphagnum and 10% reed sedge mixes. Turf performance suggested that compaction (low air-filled porosity and Ksat) was producing some stress on the 20% loam plots, yet these plots were not failing. Mixes with higher CEC also improved turf performance during grow-in. Low water retention potential in a mix with high CEC (high relative to sand-based mixes) offset this advantage as irrigation and fertilization objectives shift away from establishment toward a maintenance goal. Adequate turf establishment was observed on most mixes with inorganic amendments (exception Greenschoice). However, more consistent and higher levels of turf performance were observed on rootzones amended with organic amendments. Sand amended with kaolin-cellulose recycled paper product (Kaofin) produced highly variable turf performance, yet the longer term turf response was very positive. Thus, the product could have potential if problems at early establishment can be overcome. Longer term studies of turf responses to these rootzone mixes is needed to verify the persistence of responses, especially considering that some of the better turf responses occured on mixes having unacceptable indexes based on current evaluation criteria." |
