UNITED STATES DEPARTMENT OF AGRICULTURE <br /> SOIL CONSERVATION SERVICE 318 4th Street, Castle Rock, CO 80104 <br /> ' Fertilization rates will be according to what soil tests recommend but <br /> not less than 40 pounds available Nitrogen and Phosperous per acre. <br /> ' A follow-up application of fertilizer a year of two following seeding <br /> is also recommended. After fertilizing, the seedbed will be smoothed <br /> and firmed. <br /> ' The method of seeding will depend on the amount of coarse rock fragments <br /> in the regraded surface layer. Drilling is the preferred method, but if <br /> too many rock fragments are encountered the seed will have to be broad- <br /> cast. If broadcasting is the method chosen., then after broadcasting, the <br /> area will be dragged to cover the seed to 1/2 - 3/4 inch depth. <br /> 1 Rates applied will be according to the attached co-cons-6 form. These <br /> rates are for broadcasting. If drilling is used then these rates will <br /> be halved. <br /> It is important that all these operations be done in the proper sequence, <br /> within a short period of time, and at the right time of the year. Timing <br /> 1 should be such that no regraded area is left bare throughout the entire <br /> winter. <br /> Mulching: After seeding, a mulch of native prairie hay at 40001,E/acre <br /> 1 will be applied. This mulch must be anchored in place by means of a <br /> crimper or a tackifier, such as asphalt, which is applied with the <br /> mulch. The use of a crimper will be dependent on the amount of crushed <br /> ' rock that occurs in the regraded surface layers. Other mulchers may be <br /> used provided they meet SCS Standards and Specifications. <br /> Snrub and Tree Planting: After mulching is complete, shrubs and/or trees <br /> will be planted adjacent to the 1:1 slopes for erosion control and <br /> aesthetics. Containerized seedlings are recommended. Shrubs must be <br /> planted at 5-6 foot spacings and trees must be planted at 11-12 foot <br /> 1 spacings. Scattered plantings of additional shrubs on the 5:1 slopes <br /> are also recommended. <br /> 1 The shrubs and tress may need supplemental water the first growing season <br /> to ensure establishment. A list of approved shrubs and trees is attached. <br /> 1 _ <br /> ' er��x�C.Iir�=yE <br /> ,—^ 26 <br />
