Section 2.04.3 Page 8 December 2021 (RN-02)  <br />Developed Water Resources (DWR). This land use category ranks as the smallest of the four <br />DRMS land use categories found in the NHN Mine Area. Included in this land use category is <br />the surface area of the Second Park Lateral Ditch and the livestock ponds found within the NHN <br />Mine Area. <br /> <br />Land Capability and Productivity <br /> <br />Yields of crops and pasture for the undisturbed soil types mapped by the NRCS within the NHN <br />Mine Permit Area are summarized in the NRCS soils survey described in response to Section <br />2.04.9. According to the existing NRCS soils mapping of the site, there are seven identified <br />NRCS soils mapping units found on this site. These include soils mapping units, 10, 71, 77, 78, <br />81, 82 and 88 (see Map 2.04.9-1, New Horizon North Mine NRCS Soils Map). Crop and pasture <br />yield data are presented in the soils survey for four of these soils mapping units, that being soils <br />map units 10, 71, 81 and 82. The reported yields under high levels of management for five <br />different crops and pasture types grown on these soil types are presented in Table 2.04.3-1, <br />NRCS Land Capability & Yields per Acre of Crops and Pasture. <br /> <br />Forage production yields for the undisturbed soil types mapped by the NRCS within the NHN <br />Mine Permit Area are summarized in the NRCS soil’s survey described in response to Section <br />2.04.9. Crop and pasture yield data are presented in the soil’s survey for six of these soils <br />mapping units, that being soils map units 10, 71, 77, 78, 81 and 82. The reported yields under <br />high levels of management for native vegetation on these soil types are presented in Table <br />2.04.3-2, NRCS Land Capability & Yields per Acre by Ecological Sites. <br /> <br />Table 2.04.3-1, NRCS Land Capability & Yields per Acre of Crops and Pasture <br />Soils Map <br />Unit <br />Ecological <br />Site <br />Grass Hay Alfalfa Hay Barley Corn Silage Oats <br />10 Aquolls 4.5 tons/ac* - - - - <br />71 Nyswonger - 5.5 tons/ac 95 bus/ac 25 tons/ac 100 bus/ac <br />81 and 82 Progresso 4.5 tons/ac 5.5 tons/ac 100 bus/ac 20 tons/ac 80 bus/ac <br />*Grass Hay yields are for non-irrigated conditions, all other yields are for irrigated conditions. <br /> <br />Table 2.04.3-2, NRCS Land Capability & Yields Per Acre by Ecological Sites <br />Soils Map <br />Unit <br />Soils Phase Ecological Site Forage Production (Dry Weight #/acre) <br />Kind of Precipitation Year <br />Unfavorable Normal Favorable <br />10 Aquolls Salt Meadow 1,500 2,000 2,500 <br />71 Nyswonger Foothill Swale 2,000 2,500 3,000 <br />77 and 78 Pinon Pinyon - Juniper 100 300 500 <br />77 and 78 Progresso Semi Desert Loam 400 600 800
