| Abstract/Contents: | Results are reported for 4 topdressing studies. The studies were conducted on a Penneagle or Penncross creeping bentgrass green. The first study was initiated in 1982 and was continued through 1988. Treatments were 3 replications of 4 topdressing programs in combination with 3 and 6 lb annual N/M. In 1988, quality ratings were taken on 7/12, 8/8, 9/26 and 10/26. As observed in the past the higher nitrogen resulted in higher quality ratings than the lower N rate. The non-topdressed plots (check) ranked significantly lower than where topdressing treatments were applied. The check plots developed a significant thatch layer which resulted in a lower quality turf. Using the surface hardness tester the non-topdressed plots were found to be considerably harder than where topdressing was applied. The impact readings were in the 71-74 range on topdressed plots compared to an average value of 86 on the check plots. In spite of the thatch layer on the non-topdressed plots, the soil below the thatch became highly compacted while topdressed plots exhibited more resilience. The second study was initiated in spring 1986. Treatments were 100% sand, 100% sand and cored, 80% sand + 20% peat, and 60% sand + 20% peat + 20% loamy topsoil. Treatments were applied at 3 cu.ft./1000 every 3 weeks or 12 cu. ft./1000 in the spring and fall. In 1988, quality ratings were taken from April through November. Peak turf quality occurred on plots topdressed in spring and fall after these treatments had been applied while those plots topdressed every 3 weeks tended to have a more consistent quality throughout the growing season. On a few dates topdressing with sand mixes (80% sand, 20% peat or 60% sand, 20% peat, 20% loam topsoil) turf quality ranked better than when sand was used alone. All topdressed plots ranked better than non-topdressed plots. The third and fourth studies were established in 1985 on a modified loamy sand and dune sand, respectively. In 1988, dew ratings were taken on 10/17 for both studies and were determined on 4/26, 10/4 and 11/1 for the third and 7/6, 7/20 and 8/8 for the fourth study. Applying Sand Aid with sand topdressing improved turf quality on some dates during the growing season especially on the dune sand green. Combining coring with Sand Aid had little effect on turf quality. Plots that were cored had less dew on 10/17 than plots which were sand topdressed or not treated. This rating was taken during a period of frequent rainfall and low evapotranspiration so differential soil moisture was not considered a factor in the differential in dew formation. |
