Crop and pasture yield data are presented in the soil's survey for six <br />of these soils mapping units, that being soils map units 10, 71, 77, 78, 81 and 82. The reported <br />yields under high levels of management for native vegetation on these soil types are presented in <br />Table 2.04.3 -2, NRCS Land Capability & Yields Per Acre by Ecological Sites. <br />Section 2.04.3 <br />Page 8 <br />April 2011 <br />
