There are three major soils types at the Niew Hodzon Mane 2 area (sce Soils Map of the. perrm application): Progresso-Bond Complex, 2 to 1.5 Pa=t slopes, Bari sandy loam, 1 to 4 percent slopes; and Haptaquolls, 1 to 3 percent stages The Progresso-Bond complex is comprised of Oil peroent Progresso, 40 peroet?t Bond, 10 percent Bari (sae below), '5 percent Travesilla, and 5 perxat Bowdisb series soils. The Progresso series is classified as a fine-loamy, mixed, mesic, Ustollk 1Haplargid. The Bond series is a loamy, mixed, tnesic Lithic Ustollic Haplargid. The main dim between these two is the distance to bedrock; Bond soils are shallow (17 to 19 inches to bedr k) while Progresso soils are fairly deep (36 inches to bedrock). "This complex, is found on goody to strongly sloping irrigated uplands over much of the New Horizon Mine 2 area. The soils are shallow to moderately deep, well-drained sandy lomns formed in sandstone derived alluvium. Topsoil quality is good to an average depth of 2.1 feet.
