The Effectiveness of Leaching and Soil Amendments in Improving a Salt-Affected Soil of the Hooper Area of Utah

Haycock, Edwin Baugh 01 May 1963 (has links)
In the relatively low lying delta area west of Ogden, Utah several thousand acres of potentially productive lands have been seriously affected by the accumulation of soluble salts and the associated condition of excessive exchangeable sodium. As a part of the Weber Basin Project, much of this large area of undeveloped or only partially developed land is proposed for irrigation. Successful irrigation of these salt-affected lands, however, is dependent upon their reclamation and improvement.
