RECEIVE: <br />7. The level and slopes of the new field has to be similar since it can impact irrigation and <br />seeding processes (intermountain alfalfa management, UC California, publication 3366). <br />I reviewed soils data gathered by Key Ag Services on the Morgan property in November and <br />December of 2011. My understanding of that data is that it was orderd by DRMS as part of <br />additional permitting review and oversight. Based on a comparison of data obtained by Key <br />Ag Services. The following essential conclusions can be made: <br />1. pH of Bench 1 substitute soil > Lift B> lift A» undisturbed soil; <br />2. EC of Bench 1 substitute soil > Lift B> lift A » undisturbed soil; <br />3. OM% of undisturbed soil >> Bench 1 substitute soil > lift A > lift B; <br />. 4. Rocks >2rum ( %) of Bench 1 substitute soil >> Lift B> lift A» undisturbed soil; and <br />5. Big rocks present in the Bench 1 substitute soil were not accounted for and should be <br />quantified. <br />in summary, the bench 1 substitute soil is significantly more alkaline (high pH) and <br />saline (high EC) than the undisturbed soil. The bench 1 substitute soil contains significantly <br />less organic matter (OM %) than the undisturbed soil. Finally, the rock content and size <br />(>2mm ( %)) is higher in the bench 1 substitute soil than the undisturbed soil. AU of these <br />findings suggest that the bench 1 substitute soil is likely to be less productive than the <br />undisturbed soil.
