Soil salts affect turf mostly by withholding moisture from plant tissues. They may also compete for uptake of nutrient ions. Salts will destroy soil tilth and cause much-reduced water percolation rates. Irrigation with clean, low-sodium, fresh water is probably the most important practice to follow when leaching salts from the root zones of soils, but with lower percolation rates, this could take several months. That is why a good rainy season is usually much better for turf than a lot of irrigation.
