Study examines how herbicide adds to phosphorus levels in soil and waterways

With a strange verdict by a jury in San Francisco, it became open season on glyphosate, a common weedkiller in use for generations. One new claim is that it leads to higher phosphorous levels.Yet glyphosate only contains trace nutrients, nothing like what fertilizer has. Overuse of phosphorus-based fertilizer in some areas have led to a saturation of the soilís capacity to hold the nutrient, which increases the likelihood that any additional phosphorus applied to the land will run off into waterways and cause of harmful algal blooms and deoxygenation leading to fish death.read more
