The mixture is unique because all the varietiesused are UK bred varieties from the IBERS breeding programme, UK bred for UKconditions. All varieties are chosen to complement each other perfectly and create amixture that is environmentally and economically sustainable, perfect for the time inwhich we now live.AberNile ‘Stay-Green’ Perennial RyegrassAberNile ensures rapid establishment and gives the mixture the degree of weartolerance required for general amenity use. Unique ‘Stay-Green’ quality ensures thatthe visual appearance of the sward is maintained throughout the year. This deep rootedvariety displays exceptional drought tolerance.What the STRI says:“Stay-Green grasses differ from traditional grasses in respect of both yellownessand greenness. It is concluded that stay green grasses can increase the greennessand perceived visual quality of grass mixtures.”Comparative visual objective colour measurements of stay green and traditionalgrass mixtures – STRI Trial report 2001.AberFleece Sheeps FescueThe foundation of the mixture AberFleece exhibits very short vegetative growth andwill not typically exceed 140mm when left un-mown. A dark green colour is exhibitedthrough the year and coupled with inherent drought, low nutrient tolerance andfineness of leaf gives the mixture a strong base but fine appearance.AberCharm Slender Creeping Red FescueAberCharm produces a very dense compact sward with exceptional winter and summergreenness, which exceeded those of all other varieties in trials. Inherently fine leaved,drought tolerant and disease resistant this stoloniferous grass supports the attributesof AberFleece and AberNile and binds the mixture together.AberRoyal Browntop BentAberRoyal offers exceptional shoot density to assist AberCharm to bind the swardtogether, a very fine leaf and exceptional winter and summer greenness further ensurethe sward has a good visual appearance.Improved soil structure is seen in the soil core with ahigher clover content.AberAce White CloverAberAce is the smallest leaved whiteclover† and this makes it perfect forblending into amenity sward so thatthe benefits of clover can be utilisedwithout the plant dominating thegrasses. AberAce has a very highstolon density, this allows it to fix onaverage 150 kg N/ha, eliminating therequirement for additional fertilisersin amenity areas with low to mediumintensity usage. White clover rootsystems improve soil structure andcan help to overcome problems ofsoil compaction.Studies at IBERS have demonstratedimproved soil structure resulting froma white clover component in the sward:White clover has been shown tosignificantly decrease the bulk densityof soils and increase porosityGeneral movement of nutrientswas improved, making them moreavailable to plants and subsequentlyimproving plant health† NIAB Recommended Grass and Clover Lists 2012Sowing rate: 40g/m 2 (400kgs/ha)Overseeding rate: 20g/m 2 (200kgs/ha)Cutting height: Down to 30mmAberNile Perennial Ryegrass in trial at IBERS.15
