Abstract
Description
Erosion of open fields in North Dakota is greatest in winter and spring seasons when crops are not growing. Wind picks up soil from these exposed fields and deposits it over the entire region. Nitrate-N and Bicarbonate Soluble Phosphorus are deposited along banks of streams, fill road and drainage ditches inn little 'dune-like' mounds. These two chemicals can contaminate surface and ground water supplies. The degree to which these contaminants pollute waterways and the environ is directly in proportion to amount of rainfall and wind - erosion events.
