The incorporation of biostimulants, including microbial inoculants, into turfgrass management programs has increased during the past decade as a result of the potential benefits of their use, including increased nutrient uptake, enhanced growth, and improved stress tolerance. However, minimal research has been conducted on warm-season grasses, and...

Bermudagrasses ( Cynodon spp.) are the most preferred turfgrass species for athletic fields in the southern and transition zones of the United States. Developing and using bermudagrasses with superior traffic tolerance and surface playability under trafficked conditions benefits turfgrass managers, athletes, and sport organizations. A 2-year field...

... In fact, biostimulants have been documented to increase drought tolerance (Zhang and Ervin 2004). However, under low-stress conditions, biostimulants may result in little to no turfgrass benefit (Bolton et al. 2022). Therefore, the benefit, if any, of biostiumulants applied to well-watered turfgrass is moot; therefore, the increased use of biostimulants is questionable. ...
Nutrient use on United States golf courses increases management costs and has the potential to influence ecosystems. Therefore, it is critical to assess nutrient use and management practices to develop and teach best management practices. The objectives of this survey were to measure nutrient use and management practices on United States golf courses in 2021, and to determine if changes occurred since 2006. A survey was developed and distributed via e-mail to 14,033 United States golf facilities, with 1444 responding. From 2006 to 2021, the total projected nitrogen (N), available phosphorus (P 2 O 5 ), and soluble potash (K 2 O) applied declined by 41%, 59%, and 54%, to 54,376, 13,761, and 41,386 tons, respectively. These reductions were attributed to course closures, reduced fertilized acres, reduced application rates, and nutrient use restrictions. The percentage of facilities that did not apply P 2 O 5 increased to 21%, which is likely a result of P 2 O 5 application restrictions. Soil testing was associated with greater application rates of N, P 2 O 5 , and K 2 O. Returning clippings, using precision fertilizer applications, reducing turfgrass acreage, and considering N release from soil organic matter were associated with reduced application rates of P 2 O 5 . Golf course superintendents have contributed to nationwide reductions in N, P 2 O 5 , and K 2 O, as evidenced by the reduction in fertilized acres and the reduction in nutrient use rates from 2006 to 2021.
