Water quality is important for many agricultural uses such as livestock watering, irrigation, and spraying.The prediction that a water quality-related problem will occur requires evaluation of the potential of the water to create soil conditions that may restrict its use or that may require the use of special management techniques to maintain acceptable yields.
Water Quality Related Problems in Agriculture
SALINITY - Salts in soil or water reduce water availability to the crop to such an extent that yield is affected.
WATER INFILTRATION RATE - Relatively high sodium or low calcium content of soil or water reduces the rate at which irrigation water enters soil to such an extent that sufficient water cannot be infiltrated to supply the crop adequately from one irrigation to the next.
SPECIFIC ION TOXICITY - Certain ions (sodium, chloride, or boron) from soil or water accumulate in a sensitive crop to concentrations high enough to cause crop damage and reduce yields.
MISCELLANEOUS - Excessive nutrients reduce yield or quality; unsightly deposits on fruit or foliage reduce marketability; excessive corrosion of equipment increases maintenance and repairs.
