"In the face of climate challenges,
we deliver clear answers to lower farm costs and boost harvest yields."
Welcome, I am Donggil Jang, Chief Executive Officer of DOF.
Since our establishment in 1994, DOF has walked a single dedicated path in eco-friendly fertilizers, biostimulants, chelated micronutrients, and biological crop protection.
Intensifying extreme weather conditions—from late spring frost to historic summer heatwaves and droughts—along with escalating farming input expenses place immense burdens on modern growers. Through strategic collaborations with global leaders like Norway's YARA and continuous R&D at our in-house Biological Resources Research Institute, DOF delivers scientifically validated, full lifecycle solutions rather than mere commodities.
3 Guiding Principles of DOF
Scientific and sustainable convictions transforming the future of agriculture.
Ecological Sustainability
Utilizing natural organic matter, cold-extracted seaweed, and amino acids to minimize environmental load, restore soil ecosystems, and preserve fertile farmland.
Field-Proven Science
Strictly delivering products verified through HPLC precision analysis and extensive nationwide field trials to ensure dependable efficacy and visible growth results.
Farmer Prosperity & Cost Savings
High-absorption concentrated formulations reduce spraying frequency and labor, while maximizing premium harvest ratios to generate real income growth for farms.
30 Years of Unwavering Passion
Leading Agricultural Innovation
From our foundation in 1994 to becoming a trusted global bio-agricultural innovator, explore three decades of scientific breakthroughs, farmer partnerships, and sustainable growth.
