| Abstract/Contents: | Discusses the use of recycled water for municipal irrigation. States that "all recycled waters contain some dissolved mineral salts and chemicals. Some soluble salts are nutrients and thus are beneficial to turfgrass growth; others, however, may be phytotoxic or may become so when present in high concentrations." Lists "the parameters that should be considered when evaluating irrigation water quality", including salinity, soil water infiltration, and specific ion toxicity. Discusses the sodium adsorption ratio (SAR), stating that "the high sodium content common to recycled water can cause deflocculation or breakdown of soil clay particles, reducing soil aeration and water infiltration and percolation...soil permeability is reduced by a recycled irrigation water high in sodium." Discusses the effects of bicarbonate, carbonate, pH level, chloride, chlorine, boron, nutrients, and suspended solids (SS) in recycled water. Concludes that "recycled water quality must be analyzed on an individual basis. There are very few recycled water sources that are absolutely unsuitable for turfgrass irrigation...Climate, soil chemistry and physics, use patterns, and turf quality expectations will all contribute both to any problem and to any potential rememdies." |
