Automatic inground irrigation is a common option for residential homeowners desiring high-quality landscapes in Florida. However, rapid growth straining water supplies some areas of the state. The first objective this study was to document use Central Florida ridge region on typical (T1). second determine if scheduling by setting controllers based historical evapotranspiration (ET) (T2) and reducing percentage turf area combined with ET (T3) would lead reductions use. time frame 30months...
Double-ring infiltrometers are routinely used by turfgrass specialists, soil scientists, and other professionals to measure the infiltration rate of field sites. Measurement is important in proper golf course design development scenarios that require estimates runoff. This study compared several commonly performed double-ring methods as follows: 30- (inner) 60-cm (outer) diameter rings with a constant water depth (head), 15- 30-cm head, falling inner head. In addition, Mariotte siphon device...
Overirrigation of lawns with limited resources potable water has increasingly become an issue for the state Florida. A previous study showed that soil moisture sensors systems (SMSs) could lead to irrigation savings during relatively wet/normal weather conditions. This research, as a follow-up comparison, was conducted under dry The first objective statistically evaluate potential different commercially available SMSs half 2006. In second half, objectives were quantify use and turfgrass...
Increasing competition for water and the desire high-quality turfgrass require sound irrigation management. The main objective of this study was to evaluate two types commercially available control technologies: one based on evapotranspiration (ET) estimates other feedback from a soil-moisture sensor (SMS). Irrigation treatments were combinations controller technology: timer-based standard system (TIM), an add-on (1 set point) SMS (SMS1), (ET)-based (ETB), watering frequency: weekly, twice...
Abstract Fraise mowing and hollow‐tine aerification are disruptive cultural practices that alter soil physical properties. The objective of this study was to evaluate the effects fraise followed by on properties in a Cecil sandy loam (loam) sand‐capped soccer field (sand) beneath established ‘Tifway’ hybrid bermudagrass ( C. dactylon x transvaalensis Burtt. Davy). Three depths (0.25, 0.5, 1.0 inches) were applied mid‐June two consecutive years. Turfgrass quality (TQ), thatch‐mat depth,...
Abstract Fraise mowing has traditionally been used as an aggressive cultural practice for bermudagrass thatch management in golf and sports turf settings. Despite expanded applications, its effect on edaphic characteristics yet to be thoroughly explored. The objective of this research was evaluate physical properties two soil types beneath established Tifway hybrid ( Cynodon dactylon × C. transvaalensis Burtt. Davy) following fraise mowing. A study conducted during the summers 2016–2019 a...
Because high rates of nitrogen fertility are necessary for producing high-quality turfgrasses, quick, reliable methods determining the N status turfgrasses would be valuable management tools. The objective this study was to evaluate capacity a hand-held chlorophyll meter (SPAD-502) provide relative index concentrations, and visual quality in St. Augustinegrass [ Stenotaphrum secondatum (Walt.) Kuntze]. Two experiments were conducted greenhouse 1998 utility SPAD readings. Established pots...
New technologies could improve irrigation efficiency of turfgrass, promoting water conservation and reducing environmental impacts. The objectives this research were to quantify use evaluate turf quality differences between (1) time-based scheduling with without a rain sensor (RS); (2) schedule compared soil moisture (SMS)-based system; (3) different commercially available SMS systems. experimental area consisted common bermudagrass [Cynodon dactylon (L.) Pers.] plots (3.7m×3.7m), located in...
The plant breeding program has developed many cultivars of tall fescue ( Festuca arundinacea ) with low maintenance and stress tolerance. While the root-associated microbial community helps confer tolerance in host plant, it is still largely unknown how microbiota varies under water stress. study aimed to characterize drought-responsive bacteria fungi roots rhizosphere different cultivars. Intact grass-soil cores were collected from six grown a field trial no-irrigation for 3 years. Tall...
SUMMARY Maize seedlings have been shown to absorb more phosphorus (P) from soil long term zero‐till plots than the same after disturbance, apparently because of greater vesicular‐arbuscular (VA) mycorrhizal colonization in undisturbed soil, A growth room experiment was conducted determine effect P availability on this phenomenon. grown for three 3‐week cycles initially disturbed soil. Phosphorus mixed with create five P‐amendment rates: 0, 40, 80, 120, and 160 μg Pg −1 After each cycle, half...
Tropical signalgrass is one of the dominant weeds in Florida turfgrass industry and potentially troublesome for southeastern industry. especially problematic St. Augustinegrass sod producers because lack control options. The objectives our research were to determine effect light, pH, temperature, water potential, planting depth on tropical germination emergence. does not require light optimum at pH 5 6, temperature 25 C, potentials greater than − 0.4 MPa. shoots emerged from depths 0 7 cm,...
