Maintaining high‐quality athletic field playing surfaces without the use of synthetic pesticides is challenging. Little research is available regarding the best overseeding strategies for non‐irrigated, pesticide‐free, cool‐season athletic fields. The objectives of this study were to determine the effects of turfgrass species, cultivar, seeding rat...
Article
Weed control in turfgrass systems without herbicides can be challenging. Cost effective and reliable weed control options are needed in turfgrass systems managed organically or pesticide‐free. The objectives of this research were to determine i) the efficacy of selective, mechanical broadleaf weed control and ii) assess Weedbine injury potential in...

Many intensively trafficked areas such as athletic fields and golf courses require constant overseeding to maintain suitable turfgrass cover. Rapid seed germination and development are critical to managing these high wear areas. The objectives of this research were to determine the effect of water aeration, seed soaking duration, and water temperat...

This study examined how different presentation formats affected knowledge gain among school grounds managers. Results indicate large-group participants (presentation to ≈50 participants at a turfgrass field day) had greater knowledge retention than small-group participants (presentation to 6-10 participants at an interactive workshop). Small-group...
Article
Glyphosate is routinely used to eradicate existing turf in golf course fairway renovations. However, current label recommendations suggest delaying cultivation of glyphosate treated areas for 7 days. A 2-year field study was conducted to assess how various seedbed preparation techniques (i.e., verticutting, core-cultivation, or verticutting + core-...
Article
Many current sports venues routinely host non-sporting events that require vehicular traffic over playing surfaces. These events often occur during the season of play and are a challenge to sports turf managers to protect the playing surface. The objectives of this study were to determine the effects of portable roadways on: (i) turfgrass performan...
Article
Many organic products have been used effectively in turfgrass management programs, but their exclusive use in athletic field maintenance and effect on playing surface characteristics and soil physical properties have not been extensively researched. The objectives were to determine the effects of management regimes and overseeding perennial ryegras...
Article
Many organic products have been used effectively in turfgrass management programs, but their exclusive use in athletic field maintenance and effect on playing surface quality has not been extensively researched. The objectives were to determine the effects of management regimes and overseeding during simulated traffic on (i) turfgrass color and qua...
Article
Particle shape of prospective root-zone sands is evaluated qualitatively, but a quantitative shape determination may be more useful for sand selection. The objectives of this research were to: determine how particle shape complexity relates to bulk density, total porosity, and mechanical behavior (resistance to displacement given a vertical load);...

... In addition, these materials are easily absorbed by the plant and move quickly to be used [8]. Adding organic fertilizers by foliar feeding method works to distribute nutrients homogeneously on the plant, and since plants respond and absorb foliar nutrients faster and their costs are lower, they are preferred over ground fertilization [9]. Therefore, the study aims to increase the tolerance of the lawn and the effect of some factors that act as growth enhancers in increasing the survival of the lawn and increasing its homogeneous appearance for the longest possible period and retaining moisture through these improvements. ...
... As noted by Bartholomew et al. (2015), most school grounds managers surveyed in 2012 indicated that the perceived quality of their school grounds/athletic fields decreased with the implementation of the pesticide ban, with 40% indicating that expenditures to maintain these properties increased. Passing legislation such as a pesticide ban can completely alter the management practices of those charged with maintaining school properties (Henderson et al., 2013), along with a decrease in understanding of acceptable alternative pest management practices (Campbell et al., 2018;Wallace et al., 2016). Many cities/municipalities currently work with limited and strict financial budgets. ...
... herbicides have yet to show efficacy as high as synthetic herbicides (Miller & Henderson, 2012;Turner et al., 2012). Overseeding turfgrass areas to increase density is more successful at reducing weeds compared to organic herbicides (Miller & Henderson, 2012), and this may be a good management tool for turfgrass managers who cannot use pesticides (Elford, Tardif, Robinson, & Lyons, 2008). ...
... Figure 13a represents the juxtaposition of soil and fly ash particles. As the irregular shapes and protrusions of more angular particles likely prevent tight packing (Miller and Henderson 2011), the spherical glass-like particles of fly ash fill up the voids as shown in Fig. 13a, b, and increase the bulk density of soil. Since soil-carbon management is an important strategy for improving soil quality and mitigating soil erosion (Agronomy Fact Sheet 91 2016), the high content of carbon in fly ash will help to reduce soil loss eventually by using FAS in slope. ...
... Previous research conducted by King and Beard (1969) also reported the influence of soil texture on sod rooting, with sod transplanted on organic soil producing greater rooting than sod transplanted on a mineral soil. Henderson et al. (2009) studied the effect of the timing of Kentucky bluegrass sod installation on sod rooting strength. In their study, sod rooting was measured as the lifting force required to detach the sod from the underlying soil using a digital force gauge. ...
