P.' M. , Jackson County, Colorado. According to the Soil Survey of Jackson County Area, Colorado the entire proposed site is a Cabin sandy loam. A representative profile of the Cabin series shows that the Al and B1 Horizons from 0 to 8 inches is capable of supporting plant roots. Below 8 inches of depth only a few fine roots are found. Therefore (1) (c) (i) you should specify that the top a inches of soil shall be stockpiled separately to be used as the plant growth medium to be replaced prior to seeding. In (1) (c) (ii) should specify fertilization at recommended rates as determined by soil tests by at least one independent laboratory. The soil test should specify 1000 pounds annual production of non-irrigated native grasses. Should soil amendments be needed, they should be applied by broad casting and disced in prior to seeding. The seedbed preparation methodshould be discing. Section (1) (c) (iii) should reference the attached seed mix. The quantities for the seed mix were determined for seed drilling. Species selection was based on the Range Site Descriptions found in Section II of the NRCS Field Office Technical Guide, tempered with recommendations found in the Planting Guide for Critical Sites in Northwestern Colorado, and considerable field experience with other plantings in the local area. Seeding rates are determined using NRCS Colorado Agronomy Note No. 61 , Seeding Rates. In Section (1) (c) (iv) the seeding application method should be by drilling.
