The Goheung Song Hyo-su National Agricultural Province announced that Song Hyo-su, Kim Jae-ki, and Lee Byeong-yeon have been selected as the "2025 Jeollanam-do Organic Farming Masters." The Organic Farming Master system is a program by the Jeollanam-do government to designate farmers who have systematically established their own unique organic farming methods through long-term experience and research in agricultural fields as masters, and to utilize them as eco-friendly agriculture masters (field professors). Goheung's Song Hyo-su is developing and using a lime-sulfur farming method utilizing natural agricultural materials. To control pests and diseases, he sprays a mixture of rice vinegar, canola oil, and boiled Ganoderma lucidum water with lime-sulfur, and after reducing straw and sowing green manure, he tills the paddy deeply.
