<br />the last tillage operation for the soil to settle and <br />firm up. <br />2. Planting Period: Dormant planting is possible anytime <br />after October 15`h, or when temperatures are cold enough <br />to prevent seed germination. Avoid seeding on frozen <br />soils. Planting may also be done in the spring until <br />the end of April and between July lit and September ls`. <br />3. Planting Method: Planting will be done with a grass <br />drill or modified grain drill with depth bands or <br />packer wheels. Depth of seed placement shall between ~ <br />to 'a inch and row spacing shall be 7 to 12 inches. In <br />areas where the use of a drill is not feasible, <br />broadcasting seed is acceptable at double the seeding <br />rate. Raking will be necessary to cover the seed to a <br />depth of '-~ to 3a inch. <br />4. Seeding Mixture: See attached CO-ECS-5 grass seeding <br />planned. <br />5. Fertilization: Apply a starter fertilizer at a rate of <br />90 pounds of available nitrogen and 40 pounds of <br />phosphorus per acre (harrow into the soil) during the <br />last operation of seedbed preparation if soil tests <br />note any nutrient deficiencies. <br />6. Mulching: Clean and weed free mulches such, as grass <br />or straw hay shall be applied to seedbed. Apply enough <br />to cover soil surface well, approximately 9,000 <br />lbs./ac. Anchoring by crimping shall be done to a <br />depth of approximately 9 inches. <br />7. Post emergent weed control: Control of competitive <br />weeds shall be done. Mowing or chemical applications <br />are effective means to control weeds following grass <br />seedings. Chemical weed control can be done once <br />grasses reach the 3 to 4 leaf stage. Follow all label <br />recommendations for handling application of herbicides. <br />Chemical weed control should not be used if fortis are <br />included in the seed mixture. <br />C. OTHE_$_C9NSIDERATIONS: <br />~ - -- <br />/1. All equipment and fuel storage tanks shall be kept away <br />1\ from any drainages and precautions taken, such as <br />berming, to prevent any contaminants from entering the <br />drainages; . <br />The vegetative, soils, and climatic information for Exhibit <br />B - Site Description is attached to this letter. <br />
