Irrigation Water Testing

The quality of irrigation water is essential for the yield and quantity of crops, maintenance of soil productivity, and protection of the environment. Water quality also has an effect on irrigation systems that transport and deliver it too. Poor irrigation water quality, particularly excessive amounts of soluble salts (salinity), can cause saline and sodic conditions in the soil and induce crop water stress, resulting in a loss of crop yield, degradation of the land and pollution of groundwater. Regularly monitoring irrigation water quality is helpful to manage potential negative impacts of irrigation water.

STEMart provides comprehensive Irrigation water testing service to determine if there is evidence of negative environmental impact.
