My experience is that the cost of renting or hiring a drill will be less than the <br />oust of the extra seed, and the chances of success are significantly better. ff broadcasting, <br />incorporate the seed in some manner (drag, harrow, lightly disc, cultipack, or some other <br />method). <br />1 assume this will be an irrigated seeding, so anytime after the May 1 will work. If this is a <br />dryland seeding, seed'mg should be dale from July 1 to July 30. These are the best dates to <br />seed as far as precipitation is concerned. I wtll attach a separate sheet for a dryland seeding. I <br />normalty do not rec~mmerrd fertil'¢er, since d tends to favor annual weeds at the expense of the <br />grass. If you do use fertil¢er, d should be based on a soil test, and kept to minimal rates. <br />To briefly explain the attached seeding recommendation, amounts in column 1 are the rates for <br />a full seeding of that species. Column 2 is the percent t recommendin the mix, so multiplying <br />column 1 by column 2 equals column 3, which is the actual amount of that species to be <br />seeded, per acre. Rate shown are "Pure t_ive Seed', so be sure the seed company knows the <br />recommendation is in PLS. PLS discarnts losses due to lack of germination or other seeds, so <br />will always be less than the bulk amount needed. lt a species/variety I recommended is not <br />available or is prohibitively expensive, reduce or remove that species. Increase the percent of <br />another species to return the combined seeding rate to 100°k. Since I was not certain of the <br />acreage, I have shown the amount for 1 acre. You will need to multiply that amount by your <br />acreage. <br />Slopes to be seeded should be 3:1 or flatter. You need to stockpile or import topsoil so there is <br />a minimum of 4 inches on any area in be seeded (12 Indies would be much better). If the <br />minimum is used, disking a uric the next 2 inches will provide about 6 inches of fairly good <br />rooting medium. <br />.l,~Gs4 d ~%~Gti2Y~ <br />teven L_ Russel! <br />District Conservationist <br />
