The original <br />farm consisted of the tract on the upper right, 620 acres. Additional range land and idle <br />land was leased to obtain a unit large enough for a farm-conservation plan. Symbols show <br />erosion, slope, and soil type. Slight water erosion is shown by 2, slight wind removals and <br />accumulations by PF. More severe removals; R, moderate, S, severe, 58, very severe. <br />Accumulations: K, moderate, L, severe. The entire farm is on A slope, less than 2 percent. <br />Soil symbols are: 4, Baca clay loam; 6, Mansker clay loam; 8, Campo clay loam, all belonging <br />to group 4" medium-depth, moderately heavy soils (hardlands); 17, Spri-ngm' sandy loam of <br />group 5; 35, nandall clay, the playa lake..bed soil of group 88. <br /> <br />obtained, and a plan was worked out <br />,for the larger unit which provided a <br />total of 1,046 acres of pasture and <br />reduced the cultivated land, upon which <br />feed crops were to be planted, to 214 , <br />acres. This reduction of cultivated <br />acres was brought about by the planned <br />retirement of 46 acres in field 6, which <br />was of class VI land. Most of field 2' <br />was affected by accumulations 12 to 36 <br />inches in depth, and therefore was <br />class VI land, not suitable for cultiva- <br />tion. By leveling the drifts and then <br />farming according to the intensive <br />practices recommended for class IV <br />land, however, the operator will be <br />able to use the land safely for the grow- <br />ing of feed crops. This is preferable to <br />the plowing of grassland to provide <br />enough cropland for the unit. <br />Farming for soil and moisture con- <br />servation on this unit is illustrated in <br />figure 14. Fields 1 and 4, consisting of <br />324 acres of pasture, are contour fur- <br /> <br />32 <br /> <br />rowed. Grazing on all pastures is to be <br />limited to the carrying capacity. In <br />addition, diversions were constructed <br />to bring runoff water from the road to <br />be spread on these fields. One diver- <br />sion brings additional water into a site <br />on which trees are planted near the <br />farmstead. An earth pond, supplied <br />from a windmill, providcs storage of <br />water for the family garden and a small <br />vineyard. Narrow-base terraces for <br />moisture conservation were constructed <br />on all cropland, fiolds 2, 5, and 7. <br />Thesc fields are to be farmed on the <br />contour. Grain and forage sorghums <br />arc to be the principal crops. Whcn <br />broomcorn is seeded for a cash crop, it <br />is to be strip cropped with thc sorghums. <br />In years when moisture conditions are <br />especially favorablc, a small acreage of <br />wheat or ryc may be secdcd for winter <br />pasture in strip pattern with the sor- <br />ghums, affording additional protection <br />against wind damage.
