enough room for the animals and minimize the area that contributes polluted runoff. This is the first step to decreasing environmental risk. Table 1 can be used to properly size open lots.
If buffer space outside a pen is limited, reduce the number of animals in the lot before reducing the pen space. Keeping the same number of animals in a smaller lot may negatively affect animal health and comfort. If grass can be established or if an adequate buffer area is available, the amount of space for each animal may be increased.
Divert Clean Water
“Dirty” runoff should filter through grassy areas before reaching ditches, streams, and other surface water. “Clean” water is runoff from crop fields, hay fields, pastures, roofs, or farmsteads. Direct clean water away from the barnyard or open lot.
