Suitablity evaluation considered all soil parameters analyzed, soil descriptions and <br />the proportion of soil represented by each sampled horizon within the profiles as well the area and <br />volume from each soil map unit. <br />.I <br />Revision Date: 6/30/06 <br />Revision No.: PR-02 <br />
