Final Grading and Planting <br /> FINAL GRADING: Prior to revegetation it will be necessary to finish grading some areas <br /> where the 3:1 slope has been made. If the slope was left in a roughened condition as described <br /> previously, that is with ridges a few inches high along the contour, and there is no significant erosion <br /> with rills deeper than about 1 to 2 inches then drill seeding should be done without further treatment <br /> of the surface of the slope. But if rills have occurred then it may be necessary to use a rock rake, <br /> harrow or similar implement to drag the slope along the contour too remove the rills. This will tend to <br /> create grooves in the surface that can be a good preparation for seeding with a seed drill or by <br /> broadcasting the seed. If gullies have formed then more extensive repair may be necessary. <br /> Never try to broadcast seed on to a soil surface that has become firm and somewhat sealed. <br /> Your seeding WILL fail unless you get a big hail storm right after seeding.A hard and sealed surface <br /> must be broken up first before broadcast seeding. But such a slope can be drill seeded. <br /> If broadcasting(not recommended for this site)the surface should be very rough so there are <br /> lots of little holes and voids the seed can catch in and the surface should have a lot of loose fine <br /> material that can blow around and fill in the holes where the seed has caught,thus burying the seed <br /> with fine soil. Remember, the amount of seed needed for broadcasting is usually TWO TIMES the <br /> amount needed for drilling. Seed is expensive! Plus on a site like this broadcasting is rarely as <br /> successful as drilling unless the soil is very loose and receptive to the seed. Broadcasting also requires <br /> a lot of good luck. <br /> SEEDING THE GRADED LAND: Revegetation is the total process of establishing <br /> vegetation on disturbed land. The first step in that processes, assuming the surface is properly <br /> prepared, is seeding the land to be revegetated. And the first step in seeding is choosing a mixture of <br /> seed that will likely be successful in growing on the site being revegetated. Seed mixtures should be <br /> created by careful consideration of the local and general climatic and weather conditions. In designing <br /> a mix, it is best to consider whatever fertilizer treatments that are needed. <br /> No fertilization is considered necessary for this land.Here the seed mixture will contain <br /> species that are commonly found on this and similar grassland areas. These species are highly drought <br /> tolerant, mostly warm season grasses.
