Evaluations of turfgrass quality were based on The National Turfgrass Evaluation Program's guidelines while soil samples were analyzed for chemical attributes and microbial activity.

Fifteen soil samples and turf quality observations from each treatment were collected for pretest data. Then, post-test data were collected after each additional seasonal test period over the course of one year for each of the four plots. For the four plots, the site which received compost tea applications and regular irrigation received significantly higher turf quality ratings, and compost tea improved turf quality ratings beyond that of regular irrigation. No differences were found in microbial populations given the compost tea application. While the study results provided evidence of the value of compost tea to overall turf quality aesthetics, more research is recommended regarding compost tea applications and beneficial soil microbial populations in turf.\u0000 Species used in this study: Bermudagrass (Cynodon dactylon) L.

An improvement in seed germination and emergence can occur when a soil surfactant is applied directly to the seed and/or to the water repellent soil at sowing. Therefore, a coating process was developed to utilize seed as a soil surfactant carrier. Greenhouse experiments were conducted to evaluate establishment of perennial ryegrass (Lolium perenne L.) seed coated with a soil surfactant (SCS = surfactant- coated seed), as compared to uncoated seed (CHK). Both SCS and CHK were sown in two hydrophilic substrates (100% sand [WSAND], 90:10% v/v sand:peat [WSP], and in two severely hydrophobic sands (100% hydrophobic stearic acid-treated sand [HSS], and hydrophobic 90:10% v/v sand:peat [HSP]). Due to the weight of the coating, SCS was sown at half the amount as compared to CHK; however, final turfgrass establishment in all rootzones with SCS was similar or better than CHK. In WSAND, WSP, and HSP, the volumetric water content was consistently higher in rootzones of SCS treatments versus CHK. SCS represents an opportunity to improve stand establishment and rootzone soil-water dynamics in challenging environmental conditions such as limited precipitation.\u0000 Species used in this study: Perennial ryegrass, Lolium perenne L.","PeriodicalId":15780,"journal":{"name":"Journal of environmental horticulture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45196301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

T.M. Waliczek and N.C. Wagner.Journal of Environmental Horticulture 41(1):1–6As the fourth largest crop in the U.S. by acreage, the management of turfgrass is of environmental significance. Additionally, the turfgrass industry continues to grow along with interest in organically managing this crop. However, research regarding the use of compost tea as a management strategy for turfgrass is relatively recent and limited. Studies have suggested that compost soil amendments and teas can reduce reliance on pesticides by suppressing disease, and reduce reliance on fertilizers by increasing soil and plant health. Thus, this study investigated the effects of compost tea soil drench applications on turf quality and soil microbial activity. Results presented in this study provide evidence of the value of compost tea to overall turf quality. Specifically, compost tea improved turf quality ratings beyond that of irrigation applications. While this study illustrates turf quality can be positively impacted using compost tea drenches in turfgrass, more research is needed. Specifically, application timing, rate, and long-term effects of compost tea applications in terms of turf quality and soil biochemical attributes need to be further explored to develop best management practices.Greater Appeal of Native Plants for Environmentally Conscious Consumers. Alicia Rihn, Bridget K. Behe, Susan Barton, and Ariana Torres.Journal of Environmental Horticulture 41(1):7–13Native plants are one category that would benefit from improved marketing and communications to stimulate consumer demand. Marketers realize that not all markets are homogeneous and dividing a marketing into segments enables savvy marketers to capitalize on the attitudes, preferences, perceptions, and behaviors common within individual market segments. In the present study, researchers identified three consumer segments regarding their perceived importance of native plants: Native plant champions segment (50% of the market) believes native plants are very or extremely important; Pro-native plant segment (33% of the market) perceives them as moderately important; and Ambivalent segment (17% of the market) who believe native plants are not or only slightly important. While results showed that there were multiple differences regarding pro-environmental behavior, few differences were identified regarding demographic characteristics. Key behavioral differences in this study were the use of rain barrels, composting, and recycling gardening plastics. Marketers should consider adding native plant messages (e.g., benefits) near the areas where these products are merchandised to attract consumers to the available plants.An Update of the Literature Supporting the Economic Benefits of Plants: Part 2 – Increased Property Values.

Buxus sempervirens ‘Suffruticosa' (English boxwood) and B. sempervirens (American boxwood) were the most popular Buxus taxa planted for hundreds of years. But in the 1970s and 1980s, ‘Suffruticosa' lost popularity due to boxwood decline, and many commercial nurseries began to search for new cultivars. However, many of the popular new varieties, such as ‘Justin Brouwers', ‘Green Beauty', ‘Green Mountain', and ‘Green Velvet' were very susceptible to boxwood leafminer (Monarthropalpus flavus Schrank). In 2011 boxwood blight, caused by the fungus Calonectria pseudonaviculata, was identified in the eastern United States and Oregon. Based on early reports that both leafminer and blight were variety-specific, Saunders Brothers Inc., a wholesale nursery in Virginia specializing in boxwood, began field trials to search for cultivars with natural resistance to boxwood leafminer and boxwood blight. Reported here are field evaluations of 146 cultivars in leafminer trials and 75 cultivars and selections in blight trials. In these trials, cultivars ‘Peergold', ‘Cole's Dwarf', ‘SB 108’, ‘SB 300’, and ‘Wee Willie' and selections SB17 and 9-00-174 had low susceptibility (resistance) to both blight and leafminer.\u0000 Species used in this study: Buxus harlandii Hance; B. microphylla Seibold & Zucc.; B. microphylla var. japonica D.

Increased demand has resulted in problems with stock plant management and propagation due to the relatively small and slow vegetative growth. The objective was to determine if gibberellic acid, benzyladenine, ethephon, or auxin [indole-3-butyric acid (IBA)] plant growth regulators (PGR) applied as a foliar spray on Wee One lavender plants could be used to increase the number of cuttings for production. Fifteen replications of Wee One Lavender were evaluated for four months for plant height, width, number of cuttings, and fresh and dry weight of the cuttings. This study was replicated twice, the first experiment was performed from March 2020 to July 2020 and the second experiment from August 2020 to December 2020. A secondary propagation study was conducted simultaneously to check if PGR residuals effected rooting. The use of different PGRs caused an increase of cuttings from stock plants throughout both experiments. Foliar applications of gibberellin (ProGibb T&O) at 100 mg·L−1 (ppm) increased stem length and branching in one experiment, resulting in a higher number of cuttings produced compared to nontreated control stock plants, although that effect was not seen in the other conducted study.
