<br />any areas that may be poorly drained, tillage will be timed in order to reduce bogging, excessive <br />compaction and excessive cloddiness caused by tillage when soils are wet. The best period for <br />tillage in these areas may be in the early spring prior to the irrigation season (prior to mid-April). <br />(For flood irrigated areas) - A plow pulling a standard marker will create furrows of <br />approximately 4" to 6" depth on 30" centers, which is standard for the gated pipe used for the <br />flood irrigation. <br />7. Initial Fertilizer Application - Based on the results of the fertility testing, fertilizer of the <br />designed type will be applied at the rate specified from the lab testing. The fertilizer is in solid <br />form and will be applied by small tractor with a broadcast spreader. The fertilizer will be applied <br />in the Spring of the same year that the initial fertility testing is done. Ongoing fertility testing after <br />initial seeding is described in Section 2.05.4(2)(e) Revegetation. <br />13.3 Dryland Pasture Seedbed Topsoil Preparation Procedures <br />a) For areas less than 15% slope, where irrigation may be used in the future if water becomes <br />available, the following procedures will be followed: <br />1- Ripping - Prior to replacement of the single lift topsoil, the graded spoil (Bench 1 material) will <br />be ripped to reduce compaction. This will be done to a depth of 2 feet. This will be done by <br />dozer with rippers or a chisel plow. <br />2 - Land leveling - WFC uses a blade of 16' to 24' width pulled behind a farm tractor to level the <br />topsoil surface and allow a smoother surface for seeding. <br />3 -Rock picking - WFC will use a mechanical device such as a Vermeer rock picker that is <br />pulled behind a tractor that rakes up large rocks over approximately 2.5 inches in diameter. <br />Rocks up to approximately 24" diameter can be picked up by the device. The rocks are removed <br />from the field. <br />4 - Fertility testing - This test is conducted within 3 months of topsoil placement. Three soil <br />samples will be obtained from the top 2 feet of soil in the field to be tested. The field is basically <br />defined as that area that has recently been topsoiled. Samples will be taken and analyzed by a
