Irrigation with water high in sodium can lead to a breakdown of clay particles in the soil, a process known as deflocculation. This tends to clog the soil's void spaces, reducing the degree of aeration and reducing the soil's capacity to transmit water. The effect is of particular concern to golf course superintendents and to managers of parks where turf is subjected to heavy use. For both golf courses and high-use turf parks (for example, football or baseball stadiums), infiltration and percolation problems can render the turf unusable for its intended purpose — potentially an expensive error, if such could be avoided by a more careful choice of irrigation water.
