• Final Seedbed Preparation - (For irrigated areas) Cultipacking prior to seeding will be conducted if land leveling did not provide a smooth soil surface for seeding. The best period for tillage in these areas may be in the early spring prior to the irrigation season. For flood irrigated areas - A standard marker will create furrows of approximately 4" to 6" depth on 30" centers, which is standard for the gated pipe used for the flood irrigation. • Fertilizer Application-Based on the results of fertility testing, fertilizer of the designated type will be applied at the rate specified from the lab testing. Fertilizer applications may be delivered through the irrigation system, by tractor with a broadcast spreader, or alternate method. The fertilizer will be applied in the same year that the fertility testing is done. Ongoing fertility testing after initial seeding is described in Section 2.05.4(2)(e) Revegetation. Irrigated Pastureland Topsoil Preparation Procedures Topsoil replacement operations may be carried out during most of the year, the exception being those periods when wet conditions would preclude handling of the topsoil materials. • Deep ripping of the subsurface - Upon successful completion of placing topsoil on the ripped Bench 1 the topsoil will be ripped to a depth of at least 2 inches greater than the depth of topsoil. This will alleviate compaction of the topsoil and assist in the removal of any boundaries between the ripped Bench 1 and topsoil. • Deep ripping of topsoil - Upon successful completion of placing topsoil it will be ripped 2 inches or greater than the depth of topsoil. This will alleviate compaction of the topsoil and assist in the removal of any boundaries between the ripped subsoil and topsoil. • Land leveling - A blade may be pulled behind a farm tractor to level the topsoil surface and allow a smoother surface for seeding. • Rock picking - Rock picking is done by a mechanical device that are pulled behind a tractor that windrows rocks and then another device that picks up large rocks over approximately 2.5 inches in diameter. Rocks up to approximately 24" diameter can be picked up by the device. Sandstone lenses that are identified in any topsoil or Bench 1 will be buried in lower Bench 1 overburden, at least eight feet below the topsoil level. • Fertility testing - Three soil samples will be obtained in the field to be tested. The field is defined as that area that has recently been topsoiled. Samples will be taken and analyzed by a lab using the standard soil test for pH, salts, organic matter, nitrogen, potassium, and Section 2.05.4(2)(d) Page 14 July 2020 (MR-115)
