Abstract/Contents:"Lolium perenne and Poa pratensis are coolseason turfgrasses often mixed together and widely used for in sub-continental and mediterranean zones where, during the late spring and summer months, rainfalls are lower than the evapotranspiration (ET) and grasses suffer of drought stress. The water deficit (Rainfall < ET) can widely vary in terms of lenght and intensity, from few days without rain and/or few mm, to up to the entire period or ET. In case of water deficiency or restrictions of use of water for turf irrigation, cool season grasses may deeply suffer drought stress. Different strategies are possible: accurate irrigation, use of tolerant varieties (Bingru Huang, 2007), enhancement of the soil Water Holding Capacity via superabsorbents, nutrition strategies such as e.g. larger application of potassium (Shearman R.C., K.S.Erusha and L.A.Wit, 2005). Potassium is known for reducing drought stress due to the role of K in the control of the transpiration (Carrolm M.J., and A.M. Petrovic, 1991) (Trenholm L.E., R.N. Carrow, R.R.Duncan, 2001) but not many studies are available about the effectiveness of different sources of potassium."
