Advanced planning should <br /> enable you to avoid or minimize the disturbances on steep terrain. The following <br /> revegetation guidelines are suggested. <br /> ******Large areas of disturbance shall be graded and shaped to blend in with the <br /> surrounding topography. The soil should be packed to remove looseness. <br /> ' ******Large areas of disturbance shall be mulched to prevent soil erosion while the <br /> vegetation is establishing. This can be accomplished using oat straw or native grass hay <br /> 10 inch in length and spread evenly over the area at a rate of two tons per acre and <br /> crimped into the soil three to four inches deep. Sandy soils (i.e. loamy sands or courser <br /> surface textures) should have 'chunky" manure spread over the disturbed area at a rate of <br /> ' twenty tons per acre followed by the straw or grass hay mulching application described <br /> above. <br /> ' ******Enhance soil fertility to aid seedling establishment through the application of about <br /> 40 pounds per.acre of available nitrogen and phosphorus. <br /> ' ******Overly compacted soils resulting from equipment traffic should be ripped or <br /> subsoiled, smoothed, and then packed to the required firmness. <br /> ' ******The most successful seeding window for southeastern Colorado is from about <br /> November 15 through April 30. The optimum planting depths for the recommended seed <br /> ' mixtures is one half to three fourths of an inch with firm soil coverage surrounding the <br />
