area that has recently been topsoiled. Samples will be taken and analyzed by a lab using the standard soil <br />test for pH, salts, organic matter, nitrogen, potassium, and phosphorous. The lab will be informed that the <br />vegetation is irrigated pastureland. The reference area will be sampled separately. <br />5 - Disking - Prior to final seedbed preparation, soil conditioning and weed control tillage will be carried out <br />through disking or other standard agricultural practice. Disking will be used to condition soil, break up <br />clods, and control weeds prior to seeding. If annual weeds are a problem, several tillage operations may <br />be required to get adequate control. <br />6 - Final Seedbed Preparation -(For irrigated areas) Cultipacking prior to seeding will be conducted if land <br />leveling did not provide a smooth soil surface for seeding. The best period for tillage in these areas may <br />be in the early spring prior to the irrigation season. <br />For flood irrigated areas - A standard marker will create furrows of approximately 4" to 6" depth on 30" <br />centers, which is standard for the gated pipe used for the flood irrigation. <br />7 - Initial Fertilizer Application - Based on the results of the fertility testing, fertilizer of the designated type <br />will be applied at the rate specified from the lab testing. Fertilizer applications may be delivered through <br />the irrigation system, by tractorwith a broadcast spreader, or alternate method. The fertilizerwill be applied <br />in the same year that the initial fertility testing is done. Ongoing fertility testing after initial seeding is <br />described in Section 2.05.4(2)(e) Revegetation. <br />13.3 Dryland Pasture Seedbed Topsoil Preparation Procedures <br />For areas less than 15% slope, where irrigation may be used in the future if water becomes available, the <br />following procedures will be followed: <br />1- Ripping - Prior to replacement of the single lift topsoil, the graded Bench 1 Surface Spoil will be ripped <br />to reduce compaction. This will be done to a depth of 2 feet. This will be done by dozer with rippers or a <br />chisel plow. The single lift topsoil will also be ripped or deep disked to the full depth of the lift following <br />replacement. <br />2 - Land leveling - WFC uses a blade pulled behind a farm tractor to level the topsoil surface and allow a <br />August 2013 (PR -08) 2.05.4(2)(d)-26 <br />
