SINAN, Nov. 26 (Korea Bizwire) — Sinan County in South Jeolla Province has been engaged in a special experiment in which sun-dried salt is added to water and sprayed on crops. This experiment turned out to have generated the effect of killing two birds with one stone. Namely, it contributed to enhancing pest control, while providing additional nutrition to crops. For sweet potatoes, potatoes, garlic and spinach, the sun-dried salt-added water contributes to improving quality and productivity.
