A study was conducted in northern Colorado to evaluate the effectiveness of two compost products on improvement turfgrass color and quality, necrotic ringspot (NRS) disease suppression, thatch reduction. Two Kentucky bluegrass (Poa pratensis L.) home lawns with a history NRS were chosen for study. Treatments applied twice during 2018 growing season after all plots aerated consisted (a) inoculat...

in most semiarid and arid areas, fresh water shortage compels managers to use low quality water sources with high salinity to irrigate turf and landscape. recent research has noticed that management of nitrogen fertilization can alleviate salinity effects on plants. this greenhouse sand culture experiment was conducted in order to investigate morphological and physiological responses to salinit...

Diazinon (O,0-diethyl·0-(2-isopropyl"6.methyl-4-primidinyl) phosphorothioate) is widely used to control turfarass insect pests. Poor control of soil-inhabiting insects has been found where diazinon has been applied to thatched turfgrass stands. The purpose of this study was to evaluate the environmental fate of diazlnon applied to turfgrass stands. A microecosystem was used to follow the fate o...

Kentucky bluegrass can produce quality fairways in the Midwest if it is not mowed too short. Keep track of research. Climates vary widely across the Midwest, complicating the choice of fairway turf grass species. New epidemics of gray leaf spot have weakened the popularity of perennial ryegrass, long a preferred fairway species in many parts of the Midwest. Cultivars are available that accentua...

poa genus has a high value for grazing and forage conservation concerning thelivestock. in order to study the impacts of cold temperature and growing degree days(gdd) on seedling morphological trait and phonological development of two speciesinvolving poa pratensis and poa trivialis, this research was conducted in laboratory andgreenhouse and outdoor of research institute of forest and rangelan...

Regulatory mandates have increased demand for best management practices (BMPs) that will reduce nutrient loading on watersheds impaired by excess manure P and N. Export of manure P and N in turfgrass sod harvests is one BMP under consideration. This study quantified amounts and percentages of P and N removed in a sod harvest for different rates of manure and inorganic P and N. Six treatments co...

Fall season fertilization is a widely recommended practice for turfgrass. Fertilizer applied in the fall, however, may be subject to substantial leaching losses. A field study was conducted in Connecticut to determine the timing effects of fall fertilization on nitrate N (NO3-N) leaching, turf color, shoot density, and root mass of a 90% Kentucky bluegrass (Poa pratensis L.), 10% creeping red f...
