Urban ecosystems are rapidly expanding and their effects on atmospheric nitrous oxide (N2O) inventories are unknown. Our objectives were to: (i) measure the magnitude, seasonal patterns, and annual emissions of N2O in turfgrass; (ii) evaluate effects of fertilization with a high and low rate of urea N; and (iii) evaluate effects of urea and ammonium sulfate on N2O emissions in turfgrass. Nitrog...

BACKGROUND Turfgrass species are agriculturally and economically important perennial crops. Turfgrass species are highly susceptible to a wide range of fungal pathogens. Dollar spot and brown patch, two important diseases caused by fungal pathogens Sclerotinia homoecarpa and Rhizoctonia solani, respectively, are among the most severe turfgrass diseases. Currently, turf fungal disease control ma...

Kansas represents the northernmost region in central United States where bermudagrass (Cynodon spp.) can be successfully grown as a perennial turfgrass. Historically, few cultivars that have both acceptable quality and adequate cold tolerance been available to local growers. Because new introductions are continually being selected for improved hardiness quality, seeded vegetative types need reg...

Turfgrass is often planted along roadsides because of its adaptability and capacity to perform a wide range functions. Like other roadside vegetation, it must withstand biotic abiotic stresses while persisting long term with minimal management inputs. In cold-weather climates, snow ice practices on roads include the use deicing salts. Deicing salts can have negative impacts infrastructure envir...

Turfgrass managers have suspected that runoff-independent movement of herbicides and fertilizers is partially responsible for uneven turfgrass quality in sloped areas. We hypothesized subsurface lateral solute transport might explain this phenomenon especially areas with abrupt textural changes between surface horizons. A study was conducted to track using bromide (Br−), a conservative tracer, ...

Irrigation effects on pesticide mobility have been studied, but few direct comparisons of pesticide mobility or persistence have been conducted on turfgrass versus bare soil. The interaction of irrigation practices and the presence of turfgrass on the mobility and dissipation of mefenoxam [N-(2,6-dimethylphenyl)-N-(methoxyacetyl)-D-alanine methyl ester] and propiconazole (1-[[2-(2,4-dichlorophe...

The identification of minimal N requirements for sustaining turfgrass quality and functionality became necessary to reduce fertilization inputs avoid potential environmental impacts in the European Union. A two year study was conducted at Padova University Legnaro, northeastern Italy investigate performance four tall fescue (Schedonorus arundinaceus (Schreb.) Dumort.) cultivars (‘Lexington’, ‘R...

P turfgrasses are characterized by an extremely fine, fibrous root system. This leads to considerable frustration on the part of researchers due to the time-consuming, costly procedures required to accurately study and measure turfgrass roots. Nevertheless, the monitoring of rooting depth and functional viability on a regular basis is an important dimension in any turf manager's information ass...
