<br /> <br />-- gravel pit <br />3. A soil teat should be performed to determine the proper fertilizer <br />requirement. In lieu of a soil teat, fertilize the entire gravel pit with <br />40 pounds per acre each of available elemental nitrogen (N) and phosphoric <br />acid (P20SS). The fertilizer moat be incorporated into the top 2 or 3 inches <br />of soil using a disk or harrow implement. <br />4. Fitm the seedbed with a packer so <br />left in the soil after walking across <br />is recommended: <br />SPecles Variety <br />western vheatgrass Arriba <br />sideoats grams Vaughn or Niner <br />alkali sacaton <br />sand dropseed <br />yellow aweetclover <br />that a one-half inch boot imprint is <br />the ground.

Seeding should be done using a grass drill. The drill should be equipped <br />with a satisfactory seeding mechanism, agitator, double disk furrow openers, <br />and packer wheels or drag chains. The distance between drill rows should <br />not exceed 12 inches. Broadcasting the seed can be done in areas which are <br />inacesaible for drilling. If the seed is broadcasted, then the above seed- <br />ing rate should be doubled. The broadcasted seeds should be uniformly <br />distributed over the ground surface, and mixed into the soil with a harrow <br />or by hand ranking. Planting can be done any time between November L and <br />April 30. Seeding should not be done when the soil is frozen. The seeds <br />should be planted between ~ and 3/4 of an inch deep. <br />6. Mulch should be applied to the reseeded area to help moderate soil temp- <br />eratures, and improve soil moisture absoption and holding capacity. Grass <br />hay or cereal grain straw would work well. Apply 4000 lbs./Ac (90 lbs./ <br />1000 sq, ft.) of mulch (dry weight) uniformly over the ground surface. At <br />least half of the material should be 10 inches or more in length. Do not <br />use fine materials. The mulch should not be moldy or of otherwise low <br />quality. In addition, the mulch should be free of weeds. The mulch should <br />be anchored either with commerical netting products (on slopes steeper <br />than 3:1 ) or mechanically. The latter can be accomplished using a heavy <br />disk implement, with dull blades, to punch the mulch into the soil 2 to <br />3 inches deep. <br />7. All tillage, seeding, and crimping operations should be performed <br />across the elope when practical. <br />8. New seedlings should be protected until the stand is well developed. <br />During seedling establishment, weeds may be controlled by mowing or by using <br />an approved herbicide. <br />~<:: <br />
