| USGA Summary Points: | We continued application of treatments comprised of topdressing with three sands differing in particle size distribution. Each of the three sands were applied ten times during the growing season at two rates: 50 or 100 lb per 1,000 sq ft, a 3 x 2 factorial combination of topdressing treatments. We also continued with two levels of a cultivation factor but changed the cultivated level from hollow tine to solid tine cultivation. A ProCore® 648 setup with mini tine heads (2x5 staggered holder; 5 tines per plate) and equipped with 5/8-inch diam. solid tines was used to apply the solid tine cultivation treatment. Undisturbed core (3-inch diam.) samples of the mat layers were removed from plots in April 2023 using the methods performed during the USGA ID#: 2019-01-671 grant. Determination and analyses of the surface bulk density, pore size distribution, organic matter content, and sand size distribution of the mat layers is underway. These data will conclude the grant activities of USGA ID#: 2020-03-708 and set the benchmark for data to be collected during the grant activities of USGA ID#: 2023-01-768 Seven years of hollow tine cultivation has clearly maintained a greater surface bulk density compared to non-cultivated plots; bulk density was as much as 24% greater than the non-cultivated plot. Moreover, topdressing sand size has no detectable effect on bulk density when hollow tine cultivation was also practiced on plots; whereas bulk density did respond to topdressing sand size when coring was not practiced on plots. Bulk density was greater when topdressing used a coarser sand size on non-cultivated plots. As bulk density increased in 2023 with either hollow tine cultivation or topdressing with coarser sand on plots not receiving core cultivation, surface hardness increased. Future measurements with the USGA GS3 device should provide more insight on potential ramifications of these surface responses to playability. Non-cultivated plots retain much more water in the surface than cultivated plots. Similarly, topdressing with finer sand results in greater water retention in the mat layer than coarser sand. Greater water retention with finer topdressing sand was greatly muted by cultivation; however, topdressing with the fine-medium sand still results in more water being retained albeit to a smaller degree. Two cultivation trials were initiated on creeping bentgrass maintained as putting green turf to compare 1/2-inch i.d. hollow tine, solid tine cultivation, and a non-treated control. |
