Water testing is essential in agriculturefield also. For crop growth water testing is required. Test water to be usedfor irrigation by a reputable laboratory to determine the quality of the waterfor irrigation, choice of fertilizers for optimum plant growth, and to minimize the risk of discharging pollutants to surface or ground water. Once the source of water is identified, water to be used for irrigation should be tested by a reputable laboratory to determine the quality of the water to be used for irrigation, to aid in the choice of fertilizers for optimum plant growth, and to minimize the risk of discharging pollutants to surface or ground water. Agricultural crop irrigation and livestock water resources are major considerations for agricultural water testing.
Salts in soil or water reduce water availability to the crop to such an extent that yield is affected. Fruit and vegetable crops and the soil that they are grown in, depend on quality water that will provide the right amount of nutrients and sustain or improve yield and quality. Major concerns of agricultural water for crops are salinity, infiltration and toxicity categories. These categories can impact the quality of the water that is used for irrigation water purposes and often result in excess salt, high and low calcium in soil and water, accumulation of ions. These problems can result in low crop yields, crop damage and strange deposits on crops and plants. So water testing is essential for all agricultural activity for better crop growth and yield.
