<br />3) A soil test should be performed to determine the proper fertilizer <br />requirement. In lieu of a soil test, fertilize the entire gravel <br />pit with 40 pounds per acre each of available elemental nitrogen (N) <br />and phosphoric acid (P205). The fertilizer must be incorporated <br />into the top 2 to 3 inches of soil using a disk or harrow implement. <br />Fertilizer should be applied immediately prior to seeding, or at <br />the time of seeding. <br />4) Soils that have been overcompacted by traffic or equipment should <br />be tilled, to break up rooting restrictive layers, harrowed and <br />then rolled or packed to prepare the requfied Ei.rm seedbed. The <br />seedbed should be well settled and firm, but friable enough that <br />seed can be placed at [he recommended seeding depth. <br /> <br /> <br />5) Recocmnended varieties and seeding rates <br />Species Variety Mix Percentage <br />western wh.eatgrass Barton Rosana 35 <br />Arriba <br />switchgrass Grenville 25 <br />alkali sacaton Saltalk 40 <br />These species were selected to correspond with the eca-site description of <br />the site. <br />If desired, trees and shrubs can be planted. Species recommended are Russian <br />olive, American plum, skunkbush sumac and willow. <br />6) Seeding should be done using a grass drill. The drill should be <br />equipped with a sattsEactory seeding mechanism, agitator, double <br />disk furrow openers, depth bands, and packer wheels or drag <br />chains. The distance between drill rows should not exceed 12 inches. <br />Broadcasting the seed can be done in areas which are inaccess- <br />ible Eor drilling. If the seed is broadcasted, then the above <br />seeding rates should be doubled. The broadcasted seeds should <br />be uniformly distributed over the ground surface, and mixed into <br />the soil with a harrow or by hand raking. Planting can be done <br />anytime between November 1 and May 31. Bedding should not be <br />done when the soil is frozen. The seeds should be planted <br />between 1/4 and 3/4 of an inch deep. <br />Pounds/acre <br />pure live seed <br />5.6 <br />1.2 <br />0.6 <br />7) Mulch should be applied to the reseeded area to help moderate soil <br />temperatures, and improve soil moisture absorption and holding <br />capacity. Grass hay or cereal grain straw free of weed seeds is <br />recommended. Apply 4000 lbs./Ac. to the soil surface. At least <br />half of the material should be 10 inches or more in length. Do <br />not use fine materials. The mulch should be anchored either with <br />commerical netting products (on slopes steeper than 3:1) or <br />mechanically. The latter can be accomplished using a heavy disk <br />implement, with dull blades, to punch the mulch into the soil 2 <br />to 3 inches deep. Crimping should not sever the mulch. Mulching <br />should not be done when wind velocity exceeds 15 m.p.h. <br />
