'., <br /> <br />Class 2 lands are somewhat limited in productivity owing to a slight <br />deficiency in one or more of the factors considered. They may be <br />slightly rough or uneven, with slopes less than four percent, or <br />smoother slopes up to eight percent. The soils may be sandy or <br />clay textured, with slightly unfavorable drainage and moderate <br />salt accumulations. <br /> <br />Class 3 lands have a restricted utility because of more extreme <br />deficiencies than allowable for second class lands in one or more <br />of the factors considered. The soils may be shallow, somewhat <br />rapidly permeable, coarse-textured, and may contain limiting <br />amounts of gravel in the plow zone, but they are suitable for <br />development under irrigation. <br /> <br />Class 5A lands include those having open, pormeable soils which <br />contain a higher concentration of soluble salts than is permis- <br />sible for third class lands. They have, under present ~onditions, <br />a very low productive capacity which can be enhanced by proper <br />reclamation measures that would include leaching the excessive <br />concentrations of soluble salts out of the soil or to greater <br />depths in the profile below the root zone. <br /> <br />Class 5M lands comprise those which are affected by seepage and high <br />water table during a greater part of the gro~~ng season, or are <br />suscepttr,le to periodic.floeding. Their present limited produc- <br />tivity and adaptability, principally as meadow or pasture, may <br />be enhanced by the provision of flood control and improved drain- <br />age under project develcpment. <br /> <br />Class 6 lands include those which fail to meet the mLnlmum require- <br />ments of the preceding classes. These lands are too low in <br />productive capacity to meet all production costs and pay construc- <br />tion assessments throughout the repayment period. <br /> <br />The results of the classification show a total net acreage of class <br />1, 2 and 3 lands of 62,280 acres, of which 11,460 acres are class 1, <br />32,990 acres are class 2 and 17,830 acres are' class 3. The class 5 A lands <br />total 3,010 acres and the 5M lands comprise 9,520 acres. The total of <br />irrigated lands on the division includes 73,890 acres, of which 50,020 <br />acres 2.:'8 first, second and third class lands. <br /> <br />19 <br />
