Turfgrass Management

Studies with established turf and golf courses have indicated minimal risk of nitrate pollution of groundwater resulting from turfgrass management, but soil nitrate flux in turfgrass sod production farms and golf courses has received less attention. Information about nitrate-N flux at a particular location can be helpful to the sod producer or the golf course manager when efficiently applying N fertilizers and minimizing risk of nitrate pollution. We used an ion exchange resin capsule system to continuously monitor soil nitrate-N fluxes at 12 sites in southern Rhode Island, including turfgrass sod production farms and a low-maintenance environment. Four capsules were placed in the soil at each site and retrieved at intervals coinciding with management and meteorological events to determine nitrate ion accumulation. We found that the golf course green exhibited significantly higher nitrate-N fluxes than the sod farms and the low-maintenance turf. There was significant interaction between sampling date and study site, indicating that seasonal variation in soil nitrate-N fluxes was affected by turfgrass management. The cultural practice of late fall fertilization to stimulate early spring growth in the following year appeared to present some risk of nitrate loss during the winter from the golf course greens in our region. We conclude that site-specific and time-relevant monitoring is needed to produce and manage turfgrasses in an environmentally sound manner.

In the last ten years, the number of golf courses has been increasing in some countries as the game gains popularity. This indicates, a need to estimate the nutrient loading from golf courses in order to prevent the eutrophication of water bodies. Nutrient concentrations and flow rates of a brook were measured once a week from 1989 to 1990 at two sites: Site A of a brook flowing out from D-golf course (53 ha) and Site B of the same brook discharging into the golf course from an upper forested basin (23 ha) covered mainly with planted Japanese cypress (Chamaecyparis obtusa SIEB. et ZUCC). The bedrock of the area was granite. The annual values of precipitation and mean temperature were 1947 mm and 13.5°C in 1989, respectively. The arithmetic average values of discharge from the forested basin and the golf course were 0.392 and 1.26 mg/l total nitrogen (TN), 0.0072 and 0.145 mg/l total phosphorus (TP), 0.82 and 3.53 mg/l potassium ion (K+, 5.92 and 8.24 mg/l sodium ion (Na+), 2.1 and 9.9 mg/l suspending solid (0.001–2.0 mm, SS), 0.087 and 0.147 mS/cm electric conductivity (EC), and 0.031 and 0.037 m3/km2•s specific discharge, respectively. The loading rates of the forested basin and the golf course were 5.42 and 13.5 TN, 0.133 and 3.04 TP, 8.84 and 33.9 K+, 55.0 and 73.0 Na+, and 54.3 and 118 SS in kg/ha•y. The leaching and runoff rate of nitrogen in the chemical fertilizers applied on the golf course was calculated as 32%. These results indicated the importance of controlling the phosphorus loading for the management of golf courses.

Abstract Controlled subsurface drainage irrigation systems promote crop productivity; however, these land management systems also allow an efficient pathway for the transport of elements from soils to surface water resources. The nitrate and macro-element effluent concentrations from tile-drainage involving a 40 ha controlled subsurface drainage irrigation system are described and compared to soil nitrate availability. Soil nitrate concentrations generally show an increase immediately after soil nitrogen fertilization practices and are sufficiently abundant to promote their transport from the soil resource to the tile-drain effluent waters. The data indicates that: (1) the transport of nitrate-N in tile-drain effluent waters is appreciable; (2) denitrification pathways effectively reduce a portion of the soil nitrate-N when the controlled drainage system establishes winter-early spring anoxic soil conditions, and (3) the best strategy for reducing nitrate-N concentrations in tile-drain effluent waters is adjusting N fertilization rates and the timing of their application. The development of bioreactors for simulating wetland conditions may further limit nitrate concentrations in surface waters because of soil drainage.

Abstract One of the management techniques used in greens (final areas of the holes) of golf course is the fertilizer. To correct fertilization program of these areas should know the consumption of nutrients throughout the plant cycle. The objective was to determine the export of nutrients by clipping of Tifdwarf bermudagrass (Cynodon dactylon (L.) Pers. x Cynodon transvaalensis Burtt-Davey) used in golf courses greens in the four weather seasons, as information to improve nutritional management. The research project was conducted in two golf courses in Sao Paulo State. Four greens were studied in each field, for a period of one year, using a 4x2 factorial (weather seasons x golf courses) in a completely randomized design. The production of dry matter and nutrient concentration were evaluated, and the absorption and exportation of nutrients by leaf clippings was subsequently calculated. The amount of nutrients exported by turfgrass clippings was different between the two golf courses. The summer was the season of greatest accumulation and export of nutrients in FG, except for Fe. Autumn was the season of greatest accumulation and export of nutrients in FCA, except for Mn and Zn. Considering the amount of nutrients exported by the greens clippings of the Tifdwarf bermudagrass from the two golf courses studied, the macronutrients were exported in the following order: N>K>Ca>P>S>Mg (21.8, 4.3, 2.0, 1.9, 1.8, 0.7 g m-2) and the micronutrients were exported in the following order: Fe>Zn>Mn>Cu>B (257.8, 27.4, 23.6, 7.8, 6.0 mg m-2).

Abstract This experiment was conducted on fairways at the Jackson County Golf Course in Jackson County on the Gulf Coast of Mississippi. Soil type was sandy clay loam. Experimental design was a RCB with 4 replications. Each replication was 10,000 ft2. Treatments were made on 7 Oct between 4:00 and 5:30 p.m. Both treatments were applied with a Snyder Polyolefin Agro-Tank tractor mounted hydraulic sprayer. Total spray volume was 50 gal water/acre using 8003 T-jet flat nozzles with 50 psi. Immediately before and after treatment, VS inch irrigation water was applied to all plots except the Orthene treated plots. All plots were irrigated with V* inch of water each afternoon after treatment for four weeks. Rainfall of 1.5, 0.5, and 1.5 inches occurred on 1,3, and 4 Nov, respectively. At the time of application soil and ambient temperatures were 73° and 75° F, respectively. Relative humidity was moderate with a cloud cover of 20%. Mole cricket damage ratings were made using a 1 m2 frame divided into nine equal, square-shaped sections. The frame was placed on the ground in 20 locations/rep. The presence of mounds and tunnels was determined visually and by touch. Damage ranged from zero (no damage in any of the nine sections) to nine (nine sections contained mounds and/or tunnels). Pre-treatment counts were made on 6 Oct and post-treatment counts were made on 21 Oct and 4 Nov.

The influence of golf course operation and construction on benthic algal communities in headwater streams on the Precambrian Shield was investigated using a reference condition approach. Streams were sampled for water chemistry and epilithic benthic algae on operational golf courses, on courses under construction, and from nearby minimally impacted reference locations. Epilithic diatom community structure was different in reference streams than in operational golf course streams, the latter indicating nutrient enrichment, higher pH, and disturbance. Full counts of diatoms and soft algae revealed that there was a lower proportion of diatoms relative to other algal groups, cyanobacteria in particular, in operational golf course streams compared with samples from reference locations. Dominance by a single taxon was also significantly higher in operational golf course streams. Although differences relative to the reference streams were less marked for the streams on courses under construction, full counts of diatoms and soft algae provided evidence of disturbance and nutrient enrichment. In particular, high proportions of filamentous green algae were recorded. Overall, our results indicate that golf course land management on the Shield is associated with significant differences in the abundance of certain benthic algal taxa in headwater streams.Key words: diatoms, periphyton, biomonitoring, golf courses, canonical correspondence analysis (CCA), Precambrian Shield.

Qoi Resistance

Turfgrass anthracnose, caused by Colletotrichum cereale (ex. Colletotrichum graminicola), is an important disease of turf used on golf course putting greens. Recent management of the disease has become increasingly difficult, partly due to the possible development of practical resistance to the QoI fungicides. In all, 558 single-conidia isolates of C. cereale were collected from 10 California golf courses, 8 of which had been exposed to QoI fungicides and 2 where no fungicides had been used. Isolates were tested using a mycelial expansion assay on azoxystrobinamended media. For the two nonexposed populations, in vitro 50% effective dose (ED50) values ranged from 0.0060 to 0.089 μg/ml. All isolates from the exposed populations could not be fully inhibited by doses of azoxystrobin as high as 8.0 μg/ml. A subset of these isolates were tested in vitro with the QoI fungicides pyraclostrobin and trifloxystrobin and found to be similar in response, indicating that these isolates were fully cross-resistant to all three fungicides. In greenhouse pot experiments, three isolates nonresponsive to QoI fungicides in vitro were not controlled by label rates of the fungicides. Spore germination assays also were examined; for 10 isolates identified as sensitive by mycelial expansion assays, ED50 values for axoystrobin ranged from 0.0040 to 0.0047 μg/ml; for 25 isolates identified as QoI-resistant, 93 to 100% of the conidia germinated at azoxystrobin concentrations as high as 8.0 μg/ml relative to the nonamended check treatments. Mitochondrial cytochrome b genes from a subset of 15 isolates (12 resistant and 3 sensitive) were partially cloned and sequenced; all resistant isolates had an alanine substitution that corresponded to position 143 of the gene product. These results indicate that QoI resistance is present in California populations of C. cereale and is contributing to the difficulty in controlling this disease.
