<br />III. Drilling Seed: <br />• Page 5 of 13 <br />A. hfix seed in two batches thar are compatible, small (B. 1-5) and large/chaffy <br /> iA. 1-14). <br />B. [JSe a drill with two boxes. A larger bor, for large/chaffy seed and smaller boy <br /> 1'or small seed. A rangeland type drill is required for cocY.y, brushy sites. <br />C. 1)o not broadcast seed if at all possible. <br />D. ')rillinq is best done on a prepared seedbed, Seedbed preparation can be done <br /> in the fall, with late fall or spring seeding. Preparation in the spring <br /> pauses extreme dryness and can result in failure of vegetation establislnnent. <br /> the best time to drill is from HevemLEr through hlarch, under special <br /> situations, October, April and/or t•lay rould be authorized. There is little <br /> success when seeding occurs from June through October. Seeding during the <br /> hotter months result in the seedlings drying out and dying; during the fall <br /> months the small seedlings emerge then later winter kill in the extreme cold. <br />E. Drill mix at 8# purE live seed (PLS1 per acre which, will be about 12# bulk <br /> seed per acrE. With another 5# per acre of polyacrylamide, this will bE a <br /> drill setti.na on the small send bo>: of: Snisll Seed (B. 1-5) 9~ of 8# PI,S per <br /> acre or .7# PLS converted to .9# bulk seed plus 5# polyacrylamide for a total <br /> of 5.9# per acre drill setting. The Large/chaffy seed (A. 1-19? will be 91~ c•f <br /> 8# PLS or 7.3# PLS converted to 11.1# bulk seed per acre for the drill setting. <br />F. Consult with your seed supplier to obtain the actual figures on percent purity, <br /> percent germination, and percent pure live seed (PLS). Have the seed suppliEr <br /> figure the actual average PLS for the total mix of both A. Large/chaffy seed <br /> and B. Small Seed. <br /> 1. Compute drill setting for Large/chaffy seed (A.1-14). <br /> a. 91~ of chaffy seed infix X 8# PLS/Acre = 7.3# PLS/Acre <br /> b. 7,3# PLS/Acre _ ac[ual average ~ PLS of Chaffy seed mix __'k = Total d <br /> bulk chaffy seed __#. <br /> c. Total # bulk chaffy seed = total # per acre drill setting _#. <br /> 2. Compute drill setting for Small Seed (B.1-5). <br /> a. 9~ of seed mix X 8# PLS/Acres = .7# PLS/Acre. <br /> b. .7# PLS/Acre _ actual average ~ PLS of small seed mix _~ = Total # <br /> bulk small seed #. <br /> c. # bulk small seed + 5# polyacrylamide = Total # per acre drill <br /> setting __#. <br />IV. Mulch and Moisture Relations: <br />A. Mix with the small seed 5# par acre of coarse yrain polyacrylamide such as <br />"Hydtosource". <br />B. Mix with the fertilizer 10# of coarsE grain polyacrylamide per acre. Up to <br />eighty (80) pounds/acre polyacrylamide may be used. <br />C. BE sure each mix is drilled or spread in a sPwrt time and no[ during wet or <br />foggy periods as the polyacrylamide will swell. Don't leave the drill box cr <br />spreader Eull overnight wrtho~at coverrny to keep moisturE out. Polyacrylamid <br />is very hygroscopic and cannot be 1Eft ,rixed with seed or fertilizer for long <br />periods of time unless storage place is vary dry. <br />D. Polyacrylamide is an inert material and is preferable to straw mulch which <br />contains weeds and other noxious weeds. Straw and its decomposers can rob <br />seedlings of moisture and fertility and produce a decomposition "slime" that <br />forms small "hard pans". The process of mulching with straw is extremely <br />Expensive and the chopper/blowers are dangerous. <br />-25- <br />
