3 <br />• to cover the seed. Running a small tracked vehicle over the seeded <br /> area will also cover the seed satisfactorily. Mulches are recommended <br /> on all slopes greater than three to one. Straw or hay mulch, if used <br /> on flatter slopes, should be crimped or anchored into the soil surface <br /> with a mulch tiller, modified sheeps-foot roller or a weighted agricul- <br /> tural type disc. Mulch anchoring and seed covering can be accomplished <br /> during the mulching operation. <br /> Crass seeded with a drill should be in rows spaced six to seven <br /> inches apart. However, row spacing must be between twelve to fourteen <br /> inches to prevent covering the seed too deeply when using deep-furrow <br /> drills. Narrow spacing is desirable to reduce competition from weeds <br /> between the rows. Grass seeds should be planted one fourth to one <br /> half inch deep. Generally most of the browse species should be <br /> planted very shallow, possibly one-sixteenth to one-fourth inch deep. <br /> Grass seeding rates are expressed as pure live seed (PLS) and are <br /> derived by multiplying percent germination and percent purity and <br /> dividing by 100. Seeding rates should approximate 15 to 20 seeds <br />• per square foot on favorable sites and on critical west and south <br /> slopes the quantity of seed should be increased by 50 to 100 percent. <br /> If seed is broadcast the rate must be doubled. The grass seed per <br /> square foot should be reduced accordingly when fortis and browse <br /> are included in the mixture. <br /> Fortis in the seeding mixture should be added at about three <br /> to five seeds per square foot. Browse in the mixture should provide <br /> one to two seeds per square foot. <br /> Season of seeding should be in the fall prior to snowfall. <br /> Seeding just prior to the season that receives the most dependable <br /> precipitation gives the best results. <br /> Fertilization of the rehabilitated area should be based upon <br /> soil testing. Generally, fertilizer applied at the end of the first <br /> growing season or the beginning of the second growing season helps <br /> to avoid rapid weed growth. When fertilizer needs are known, steep <br /> slopes should be seeded and fertilized at the same time in order to <br /> work the fertilizer into the soil. <br />• <br />
