This study has been undertaken because of the limited knowledge of the effects of irrigation on soils in semi-arid and sub-humid climatic areas. The objectives of this research are: 1.To study irrigation systems now in operation and to determine by soil and water analysis the rates of salt and alkali accumulation; 2. To determine, by a multiple regression analysis, the laboratory determinations which most accurately estimate the exchangeable-sodium-percentage of the soil; 3. To determine the effect of various qualities of irrigation water on the accumulation of salts and alkali in the soils being developed for irrigation in South Dakota; 4. To evaluate present water quality criteria and their suitability to the conditions that exist in South Dakota.
