According to data from the Rural Development Administration, the spraying of sun-dried salt-added water into the cultivation area after diluting the density of the salt to an adequate level contributes to preventing powdery mildew by 81 percent and gray mold rot by 49 percent.
For sweet potatoes, potatoes, garlic and spinach, the sun-dried salt-added water contributes to improving quality and productivity.
