Conservation buffers are strategically planted grasses, trees, and other ground cover.
When planned and implemented to match the site, they reduce the impact of runoff from adjacent fields.
Buffers can reduce up to 80% of sediment and 40% of phosphorous (on average) from reaching surface water by trapping it in the vegetation.
Significant amounts of nitrate can be removed from the system by the root structure and stored in the plant material.
Buffers also can reduce wind borne pollutants.
Several years of cost analysis show areas suitable for buffers are often the least profitable areas in the field. In fact, the continuous buffer sign-up for the Conservation Reserve Program (CRP) can turn unprofitable acres into a profitable situation.
Buffers can also:
Trap any escapes of crop protection products on the surface and in the root zone to allow natural decomposition processes to occur
Allow plants in the buffer zone to use potential pollutants as nutrients
Reduce wind and water erosionIncrease infiltration and reduce runoff
Increase fish and wildlife habitat
Trap snow to increase moisture available to crops
Add aesthetics to the landscape both visually and in terms of plant and animal populations
