In this study, we investigated the utilization of waste slag sand as a topdressing material for zoysiagrass and evaluated its potential benefits in promoting plant height, normalized difference vegetation index (NDVI), and coverage. Waste slag sand was applied either alone or in combination with river sand and compost, and plant growth over time was monitored with reference to control plants. Results indicated that while waste slag sand alone had a relatively lower impact on plant height than the control, and in combination with compost, it significantly enhanced growth, resulting in higher relative height values. NDVI measurements showed improved plant health and greenness in the areas where waste slag sand and compost mixtures were applied, surpassing those of control, waste slag sand, and river sand alone. The coverage area index also revealed that this combination supported more extensive ground coverage, thereby increasing its effectiveness in promoting turfgrass density. These findings suggest that waste slag sand, particularly in combination with organic matter like compost, can serve as an effective and sustainable topdressing material for zoysiagrass. Future research is needed to evaluate its long-term effects, including on other turfgrass species, broader applications, and other traits, such as root morphology and chlorophyll content.","PeriodicalId":100722,"journal":{"name":"International Turfgrass Society Research Journal","volume":"15 1","pages":"1075-1079"},"PeriodicalIF":0.0,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/its2.70065","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145761250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its relatively slow establishment rate, especially using vegetative propagation methods such as sprigging and plugging, limits its widespread adoption. This study evaluated the impact of planting rates and varying nitrogen (N), phosphorus (P), and potassium (K) fertilizer combinations on the establishment and performance of newly released cultivar Lobo™, a Z. japonica × Z. matrella hybrid. The experiment took place at Lake Wheeler Turfgrass Field Laboratory (Raleigh, NC) in 2024. Two planting rates (sprigs at 5 or 10 m3 ha−1) were tested, supplemented with low (9 plugs/plot) and high (16 plugs/plot) plugging rates due to drought-related sprigs loss. Sixteen fertilization treatments, combining four N rates (0, 12.5, 25, and 50 kg ha−1), two P rates (0 and 25 kg ha−1), and two K rates (0 and 25 kg ha−1), were applied weekly for the first month, then monthly. Results showed that planting rates and N rates positively influenced percent green cover. However, increasing N rate beyond 12.5 kg ha−1 did not yield additional benefits, suggesting an optimal economic threshold for sod growers. Turfgrass color, indicated by normalized difference red edge, was enhanced by a higher N rate and planting rate, and was subtly increased by a higher K rate. Phosphorus rates had no significant effect on establishment or color. This study highlights the importance of optimized planting and fertilization strategies for efficient and cost-effective establishment of Lobo™ zoysiagrass.","PeriodicalId":100722,"journal":{"name":"International Turfgrass Society Research Journal","volume":"15 1","pages":"1113-1117"},"PeriodicalIF":0.0,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/its2.70075","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145754575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Field research evaluating soil surfactants on turfgrass rely on measuring soil volumetric water content (%VWC) repeatedly over time. Field ecology research often involves sampling in a transect and utilizing the data to calculate the coefficient of variation (%CV) to provide further insight into data uniformity. Therefore, a field study was conducted on a mostly creeping bentgrass (Agrostis stoloniferous L.) practice putting green in the Mid-Atlantic US region to evaluate sampling the VWC along a transect. Two soil surfactants (“A” and “B”) were repeatedly applied in a program from April through October 2023, and a non-treated control was also included. The VWC data were collected every 14 days in a transect as 10 measurements per plot, and visual turfgrass quality also were evaluated. Plots treated with soil surfactant A exhibited consistently higher VWC, more uniform and consistent VWC over time, and higher visual turfgrass quality versus plots treated with soil surfactant B or non-treated plots. Overall, monitoring rootzone VWC as 10 equidistant measurements along a transect facilitates improved data analyses and is useful for calculating the CV for further insights on soil moisture uniformity and consistency. Therefore, this ecological transect method could be a useful approach to measuring and monitoring soil or rootzone volumetric water content in turfgrass research.","PeriodicalId":100722,"journal":{"name":"International Turfgrass Society Research Journal","volume":"15 1","pages":"1213-1222"},"PeriodicalIF":0.0,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/its2.70052","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145761233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to this situation, the integrated pest management (IPM)-Project Golf 2020–2023 was implemented by Scandinavian Turfgrass and Environment Research Foundation and the R&A Trust Company (No. 1) Limited (the R&A) to evaluate and assess new techniques and alternative products to control diseases such as microdochium patch (Microdochium nivale) and dollar spot (Clarireedia spp.) with the goal to reduce the use of fungicides. As a sub-project, the use of UV-C radiation was carried out to investigate the effectivity of UV-C radiation to prevent both diseases on golf course putting greens. This study was conducted from spring 2020 until spring 2022 on a putting green (50% Poa spp. and 50% Agrostis spp.) at the golf course of Osnabrück Golf Club (Germany). The dosages of UV-C radiation were 0 mJ/cm2, 7–8 mJ/cm2, 35–40 mJ/cm2, and 70–80 mJ/cm2 which were applied using the SGL UV-C 180 just prior to and during periods of active dollar spot and microdochium patch development. The results of the UV-C application determined that highest UV-C dosage was able to reduce the severity of dollar spot and microdochium patch by 46%–81%. Thus, UV-C radiation with enhanced dosages can be a helpful tool in IPM strategies for turfgrass management to reduce chemical fungicides with view on tolerance levels of disease infestation.","PeriodicalId":100722,"journal":{"name":"International Turfgrass Society Research Journal","volume":"15 1","pages":"949-957"},"PeriodicalIF":0.0,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/its2.70058","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145761200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Portable hand-held environmental monitoring instruments are commonly employed by practitioners; however, it is not clearly understood as to the ideal location within the soil profile to monitor and measure water and salinity. Soil samples were collected from 30 golf course sand-based putting greens during May–September in 2005–2020, representing cool- and warm-season turfgrasses in nine countries in North America, Europe, and Asia. At each site, 24 soil cores 1.9-cm diameter × 18-cm depth were randomly extracted, resulting in 12 soil cores partitioned into 3-cm segments at 0- to 18-cm depth (i.e., 0–3, 3–6, 6–9, 9–12, 12–15, and 15–18 cm), and 12 soil cores separated into 6 cm (i.e., 0–6, 6–12, and 12–18 cm). All soil samples were subjected to laboratory analysis to determine soil moisture saturation index (percent saturated water loss upon drying) and salinity (electrical conductivity of saturated soil-paste extract [ECe] and electrical conductivity of soil pore water [ECw]). Analysis of soil data confirmed soil moisture and salinity were not uniformly distributed throughout the rootzone from the 0- to 18-cm depth, and the majority of soil moisture and salinity were measured and observed within the upper layers at the 0- to 6-cm depth. Therefore, the analysis of soil samples from golf course putting green sand-based rootzones indicates an optimal placement for monitoring the highest concentrations of water (determined by the soil moisture saturation index) and salinity (determined by ECe and ECw) was 6 cm (i.e., the 0- to 6-cm depth). When using soil moisture and salinity meters, turfgrass practitioners should monitor putting green rootzones at the upper 0- to 6-cm depth.","PeriodicalId":100722,"journal":{"name":"International Turfgrass Society Research Journal","volume":"15 1","pages":"865-872"},"PeriodicalIF":0.0,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/its2.70042","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145761443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
