Key Effects
Four actions that contribute to soil environment and crop growth management
01
Acidified Soil Improvement
Gradually improves acidified soil to create a soil environment better suited to crop growth. With continued use, soil condition improves progressively, supporting healthy soil management.
02
Suppression of Harmful Bacteria & Pathogens
Suppresses the proliferation of harmful bacteria and pathogenic microorganisms in the soil and around crops, creating a healthy growing environment. This can support eco-friendly farm management with reduced pesticide use.
03
Bacterial Leaf Blight Management in Rice
Helps suppress the occurrence and spread of bacterial leaf blight, a significant problem in rice cultivation, and supports prevention and management of the disease.
04
Long-Term Soil Health
Regular, sustained application rather than one-off use gradually improves the soil environment and can support stable crop growth and improved productivity.
500x
Surface Area Expansion
Over 500 times that of conventional sulfur through 3µm nano grinding

Global Reach
Beyond Sri Lanka,
to farmland worldwide
In 2022 we completed formal export declaration and customs clearance for Sri Lanka (DAHAMSA INTERNATIONAL). We continue to build trust through welcome events for local government and state-enterprise delegations, and through large-scale drone application trials on sugarcane and rice farms.
"For more than ten years we struggled badly with viruses. I have farmed for twenty years, and after using JIPYEONG I saw growth like this for the first time. The difference is unmistakable."
