Abstract

In the arid west large areas of soil contain soluble salts in sufficient concentrations to inhabit crop growth. Of the 1,416,957 acres of soil surveyed in Utah from 1899 to 1920, reported that 43.58 per cent contained 0.2 per cent or more of salts. The management and reclamation of these soils present serious problems. The difficulties are further accentuated by the fact that many streams used for irrigation contain appreciable quantities of salt. Generally under these conditions removal of the salt from the soil becomes impracticable, and the problem is one of elarning how to get along in spite of the salt. An early study by Lipman and gericke and some preliminary tests at the Utah Agricultural Experiment Station have indicated that crops growing on salty soils may be benefited by applications of copper salts. Because of the economic importance of any procedure for increasing crop production on salty soils, additional studies were proposed to further investigate the problems involved. The research on this problem was planned to investigated the value of copper sulfate in increasing crop yields on salty soils and to study ways in which copper might benefit plants under these conditions. Further studies were planned to determine whether an antagonism can be produced in saline soils between sodium chloride and copper sulfate and to determine whether this antagonism is specific for copper or whether it might also be produced by other ions.
