dc.description The Carrington Research Extension Center, which began in 1960, was created to provide research on the advancement of both private and public irrigation development in North Dakota. Underground irrigation is the most direct route of water from point of delivery. Also, underground pipes wouldn't interfere with field operations. Seepage and evaporation losses could be eliminated. These various types of pipes are discussed in this article. The greatest concern regarding any underground irrigation system in North Dakota is 'Will it freeze?'. The three most factors affecting 'frost heave' were concluded as being: depth of free water table as related to depth of frost penetration, amount of capillary water movement through a soil profile, texture and permeability of the soil and duration of the annual freeze period.
