Description:
A 4-year study was conducted on the effects of precipitation management on salt movement and spring wheat yields on an imperfectly drained saline silt loam in the northern Red River Valley of North Dakota. Partial leaching by artificially applied water at the beginning of the experiment was compared to leaching benefits by impounded precipitation. Average monthly water table fluctuated from 2 to 11 feet with rainfall and was usually lowest in late winter or spring and highest during the summer. Average yearly precipitation is 20 inches.Impounded precipitation was found effective in partially desalinizing the soil. Summer rain was more effective than winter precipitation. Wheat yields were inversely related to soil salinity with the highest correlation coefficients occurring on springtime data for the 6- to 16-inch depth.
