Phospholutions is developing a new fertilizer additive called RhizoSorb to improve phosphorus use efficiency in agriculture. RhizoSorb is embedded into fertilizer during production and releases phosphorus based on plant needs rather than environmental conditions, allowing crops to utilize more of the applied nutrients. Trials have shown RhizoSorb can preserve crop yields while reducing phosphorus use by 50%. This has sustainability benefits like decreasing fertilizer costs, runoff, and greenhouse gas emissions. Phospholutions is currently selling RhizoSorb in the US and seeking funding to further partnerships and commercialization efforts to make phosphorus fertilizer use more efficient and sustainable globally.
