| Abstract/Contents: | "Physical property criteria are used to select construction materials for golf putting greens, however, relationships between physical properties and turf performance are not well known especially across microenvironments. This field study evaluated creeping bentgrass (Agrostis palustris Huds. `L-93') establishment as affected by root zone physical properties and microenvironment. Five sand size distributions were used to construct root zone plots in two microenvironments varying in air circulation. Microenvironment had a subtle but inconsistent effect on turf establishment. Over both microenvironments, rapid establishment was associated with a capillary porosity (water retention) of 0.250 m3 m-3 or greater. Reducing the depth of the root zone profile was more effective in improving establishment on coarse-medium and medium sand mixes. Turf cover and ratings of turf density and quality corroborated establishment ratings. In contrast to shoot responses, root mass one year after seeding was strongly affected by microenvironment; 32% more root mass had developed under turf in an open microenvironment. Root mass was greater in the 300 mm deep coarse sand mix at depths below 150 mm than some of the finer sand mixes. Root mass was similar in shallow depth sand mixes compared to 300 mm deep mixes. Thus, turf establishment on mixes with a capillary porosity equal to or below 0.204 m3 m-3 can be delayed even though development at depths below 150 mm may be increased. Reducing profile depth of sand mixes having low capillary porosity can improve turf establishment rate without detriment to root system development." |
