A reclamation program was developed for soils <br />with adverse saline/sodic concentrations and increased produc- <br />tion/development cost considerations were identified based on the <br /> <br />observed soil physical characteristics. <br /> <br />1.3.4 Crop Suitability <br />The suitability and estimated yield of crops judged suitable for <br />production under natural resource and climatic conditions on Ute <br />Indian Reservation lands are summarized in Table 1.3. Table 1.3 <br />summarizes both traditional and non-traditional crops judged to be <br />capable of sustaining economic levels of production under irrigation <br />considering project area natural resource and climatic conditions. <br />Dryland crop suitability and yield are also identified based on the <br /> <br />1- 11 <br />
