Seasonal variations in salinity of soils supporting different levels of barley grass (Hordeum murinum L.)

Abstract

Abstract Measurements of soil salinity taken throughout the year from barley grass sites and nearby areas showed that salinity levels tend to be high in soils where barley grass occurs and that sahmty vanes conSIderably dunng the year, reaching particular high levels In the late summer on barley grass sites.It is suggested that this high sahmty senously affects the survival of perennial pasture species over the summer whereas barley grass, being an annual,avoids these adverse growing conditions and can readIly Invade the bared areas in the autumn.
