WAYNE COOLEY <br /> AREA EXTENSION AGENT (AGRONOMY) <br /> TRI RIVER AREA <br /> COLORADO STATE UNIVERSITY COOPERATIVE EXTENSION <br /> AND <br /> JOHN MURRAY <br /> RANGE CONSERVATIONIST <br /> NATURAL RESOURCE CONSERVATION SERVICE (NRCS) <br /> MONTROSE, COLORADO <br /> LAND PREPARATION: The first step to be taken in an area that <br /> • will need to be reclaimed is to stockpile the topsoil for use <br /> when reseeding. Depending on the location, this will be the top <br /> 611 to 1211 inches of soil. <br /> The disturbed area that will be reseeded should have slopes that <br /> are no greater than a 3 to 1 ratio (33% slope) . <br /> Activities that create considerable soil compaction (e.g. Gravel <br /> Pits) , a ripping operation of 8 to 10 inches should take place <br /> before replacing the top soil. The scarification process on <br /> highly compacted soils provides at least two benefits. <br /> Fracturing the soil allows for root penetration and forms pockets <br /> for capturing moisture. <br /> After the topsoil is replaced, a firm seedbed is required before <br /> planting grass seed. A common cause of seeding failure is <br /> inadequate seedbed preparation. The seedbed should be firm <br /> enough to allow good seed-to-soil contact. A firm seedbed helps <br /> to retain moisture in the top 1 to 3 inches of soil and prevents <br /> excessive seeding depths. <br /> SEEDING TIME: The seeding time with the greatest success is a 1 <br /> dormant seeding from October 1-15 for areas that cannot be <br /> irrigated. At this time the soil temperature is cool enough to <br /> prevent seed germination until the following spring. Grass seed <br /> . starts germinating when the soil temperature reaches 40 to 42 <br /> 619 Main IMI North 2rA County Courthoutc Anncx <br /> P.O.Box 2I4000-50241 Friendship Han 5rh&Palmer <br /> Grand Junction,Colorado 815M-5Ma Nonrrore.Colorado atrdt DOM Colorado 91416 <br /> t303l 244-104 OW)1arr.14]5 001)a7t.t5tV <br /> Colorado State Unllxrsity.U.S. Department o/Agrdcultum and Delta.Mesa.Montrose and 0urav Counties cooperating. <br /> Coomrative Extension programs ate available to all without discrimination. <br />
