The predominant grasses consist of blue grama, buffalo, and <br />three awn. Forbs are a native mixture of annual and perennial forbs. <br />For soils description see attachment. <br />Enclosed is a admendment to the Gaede Pit planning reclamation <br />recommendations for the pit located in the S1/25E1/4, SE1/4SW1/4 of <br />section 36-8-56. <br />Planning considerations for reclamation of the site consists of: <br />1. Top soil should be stockpiled before mining begins and spread <br />evenly over the surface after reclaimed. Soils must have sufficient <br />depth to support the grass mixture to be seeded. The area should be <br />shaped to the undisturbed area. Slopes should not exceed 3:1 and <br />should be flatter where feasible. <br />2. The seedbed should be well settled and firm but not compacted. <br />If heavy equipment traffic has compacted the area it should be ripped <br />and smoothed. The seedbed should be free of weeds. <br />3. A soil test should be performed to determine the proper <br />fertilizer requirement in both types and amounts. In lieu of a soil <br />test the planting area should be fertilized at a rate at least 40 lbs. <br />of nitrogen and 40 lbs. of phosphate. Animal manure may be used to <br />supply all or part of the nutrients. Fertilization should occur around <br />seeding time of the grass. <br />4. The seed mixture should consist of blue grama, sideoats grama, <br />switch grass, and little bluestem ( see attached seed sheet). Grass <br />drilling should occur between November 1 through May 20th. Weeds <br />should be control mechanically or chemically until grass is <br />established. Grazing should be excluded for two growing seasons from <br />the time of planting from the seeded areas. Fencing maybe needed to <br />achieve this. <br />5. A minimum of 4000 lbs. of grass (native) mulch per acre should <br />be applied to the surface after the grass has been seeded to hold the <br />ground until the grass has established. The mulch should be crimped <br />into the surface with a mulch crimper. The mulch should be weed free <br />and not moldy. <br />If you need any furthQr assistance please contact us. <br />Brian C.
