Ed Settle • <br />_ Corn Construction <br />Page 2 <br />2ECLAMATION RECOMMENDATIONS: <br />Successful reclamation and revegetation of this area is dependent upon sev- <br />eral factors other than the actual seeding. Final slope grades should not exceed <br />2:1 in steepness, with 3:1 or 4:1 slopes being even better. In general, the <br />chances of successfull revegetation increases as the percent slope decreases. <br />Small areas with slopes steeper than 3:1 are often unavoidable but should be <br />kept to a minimum. <br />During gravel extraction any topsoil should be striped and stockpiled for <br />later use. This soil material should be spread out over areas to be reseeded <br />to a depth of 6 to 8 inches. Underlying material should be scarified to pro- <br />vide a bond between substratum and the topsoil. It is realized that not all areas <br />will be able to be topsoiled, however, as much area as possible should be covered. <br />Without topsoiling, revegetation success is unlikely. <br />Seeding preparation is probably the most important factor determining the <br />success in establishing permanent vegetative cover. Seed should be placed -h'" <br />to 1 inch deep in a friable but firm seedbed. All seed must be covered. Dril- <br />ling the seed is preferred to broadcasting. <br />The best time to seed non-irrigated areas is in the late fall, just prior <br />to the ground freezing. This allows the seed to stay in the ground until spring <br />when it can germinate and make the best use of spring moisture. <br />Irrigation during the first growing season would be beneficial. <br />Sincerely, ~,~ <br />Mark W.
