Iowa leads the nation in the number of conservation buffers, which naturally filter sediment and nutrients out of water. A saturated buffer is a type of buffer that lets scientists monitor water that flows from farm fields after heavy rain. By diverting some of the water underground to flow above the ground, we let agriculture nutrients (such as Nitrogen and Phosphorus) soak back into the soil. Iowa water quality is improved and farmers keep their nutrient-rich soil, a win-win!
