Controlled drainage uses stoplogs or flashboards to dam outflowing drained water, resulting in a rising water table. This keeps the soil appropriately saturated, improves yields (26-60bu/ac), decreases expenditures on fertilizers (~30%) and decreases dependency on inefficient irrigation techniques during periods of limited rainfall.

This environmentally responsible option also decreases water outflow by 20%, reduces nitrate losses by 45% and cuts phosphorus runoff by 35%. These drastic reductions have a positive impact on the environment and your bottom line.
