Hiland soils have less than 15 percent <br />carbonates in the calcic horizon. Solirec soils are in MLRA 34 and receive maximum precipitation in <br />spring and fall. Similar soils and previously competing series are (Ustic Haplargids) Bowback, Cambria, <br />Cushman, Decolney, Forkwood, Fort, Maysdorf, Pugsley, Teckla, Yenlo and (Ustollic Haplargids) Balon, <br />Buckle, Cerrillos, Clovis, Fattig, Fernando, Flaco, Gaddes, Gapbutte, Hagerman, Harboard, Los <br />Alamos, Millett, Oelop, Olney, Palacid, Penistaja, Pokemen, Potts, Progresso, Quagwa, Redpen, <br />Scholle, Selpats, Spangler, Spenlo, Sundance, Tapia, Threetop, Toluca, and Tuweep. Only Cerrillos, <br />Clovis, Fernando, Millett, Scholle, Tapia, Toluca, and Tuweep soils are reclassified to Calciargids under <br />the 7th Edition. Cerrillos soils are dryest from October to May. Clovis soils receive more than half of their <br />precipitation between the months of July and October. Fernando soils contain 50 to 80 percent silt in <br />(Revised June 2008) Attachment 2.04.9-3-4
