What is Source?
Source operates at the intersection of plant physiology and sustainable farming. Its core product, a specialized foliar spray, functions as a biological catalyst that increases nutrient efficiency by fixing nitrogen and unlocking phosphate throughout the growing season. This approach directly addresses the rising costs of synthetic fertilizers and the environmental challenges associated with nutrient runoff. By improving the internal metabolic processes of plants, Source enables growers to achieve higher yields with lower input requirements, effectively bridging the gap between intensive farming and ecological stewardship. The company's market position is bolstered by its ability to integrate seamlessly into existing agricultural workflows, making it an attractive partner for large-scale cooperatives and commercial growers globally.
