You indicated this was for native shrubs and grasses. <br />The nitrogen and phosphorus levels are low in this soil. Generally, nitrogen is not <br />recommended for establishment of perennial dryland grasses. More often steps must be <br />taken to reduce the nitrogen level prior to planting native dryland grasses and shrubs. The <br />latter is not the case for this site. <br />The phosphorus test Ward uses needs to be converted to AB -DPTA test and that is <br />accomplished by multiplying by .17. Thus the phosphorus level of this soil is 1.87 ppm. <br />Apply and incorporate 40 lbs P205 /ac prior to seeding. <br />All other nutrients are adequate. <br />Sincerely, <br />Curtis E.
