Introduction
The vegetative buffer or filter area allows runoff nutrients from manure to be taken up by the plants in the filter and ensuring that no contaminated water enters movement lanes or waterways. This buffer was designed according to USDA-Natural Resources Conservation Service specifications for size and grass composition. The buffer extends 35 feet behind the pit down a gradual slope. The vegetative buffer is composed of cool-season grasses and legumes including white clover (2 lb/acre), orchard grass (6 lb/acre), and smooth brome (6 lb/acre). The buffer is fenced off from animals and only maintained with a mower as needed.
