Researches in selected areas have shown that an incorrect siting of roads in farming aress may lead to considerable pollution of creeks, lakes and reservoirs by phosphorus, nitrate and ammonium present in the runoff. Farm roads should not be sited in basins or depressions. They should not be built up slopes greater than 8%, or across slopes greater than 3%. When built across slopes, the use of the land above the road for arable farming and the land below the road as grassland or woods is recommended.
