| Abstract/Contents: | "The overall goal of this project is to develop a better understanding of the impact of grow-in procedures on putting green establishment and performance. Impacts on the physical, chemical, and microbiological factors associated with the USGA root zones and rhizosphere are emphasized in the project. The five year project is composed of three phases, One: Construction and Grow-in, Two: Microbial Community Assessments, and Three: Grow-in Procedure Impacts on the Long-term performance of the Putting Green. Phases One and Two span three year periods, while Phase Three will involve experiments repeated over the five years of the project. Two separate USGA-specification root zone mixtures - one composed of sand and peat (80/20 ratio) and one a combination of sand, soil, and peat (80/5/15 ratio) - were developed in 1996. Materials used for construction complied with USGA Greens recommendations for physical characteristics and organic matter content. First year greens (1997 Greens) were constructed in late summer of 1996, allowed to settle over the winter, and were seeded with Providence creeping bentgrass (1.5 lbs/1000 ft2) in the spring (May 30) of 1997. Second year greens (1998 Greens) were constructed in the summer of 1997, allowed to settle over the winter, and were seeded with Providence creeping bentgrass (1.5 lbs/1000 ft2) in the spring (May 27) of 1998. Results to date indicate the following: Microbial biomass was not affected by root-zone mix or grow-in procedure on plots established in 1997. Microbial biomass increased over 200% from Spring to Fall and decreased 40-60% as sampling depth increased. Water infiltration from these same plots were not affected by root-zone or grow-in procedure when measured in 1998. The following establishment results were similar in plots established in 1997 or 1998: For two consecutive years it was found that higher inputs will initially increase cover during grow-in. This increase may not translate to earlier opening for play if environmental stress conditions occur that result in damage to lush, immature turf. A root-zone mix containing soil will establish quicker and recover from environmental stress faster than a soilless mix. A soil-containing mix will also be harder and may result in longer ball roll distance. Addition of soil to the root zone mix will not effect water infiltration during the establishment year." |
