on Cal Poly Land Salinas Soil |

  |

| The
Salinas series is a very deep and well-drained soil that has formed on water transported alluvium derived from sedimentary rocks and deposited along streams. The soil fills valley floors as alluvial fans and plains. Included with the soil are small areas of Cropley and Mocho soils. The Cropley soil contains more clay while the Mocho has a neutral pH throughout the profile. Our best and most productive farmland is located on these soils. The area around the Crops Unit, the Citrus Orchard, the alfalfa fields along Highland Drive and Field 25 (the vegetable plots along Highway 1) are underlain by these soils. They are listed as Class I and II land when irrigated. Cal Poly has control of less than 100 acres of these excellent soils. It is often a challenge to prevent development on these prime agriculture resources.
