• prefer theses grasses. They are also suited to irrigated conditions. Seed Mix #7, containing alfalfa, <br />orchardgrass and meadow brome and reflects one of the most commonly recommended mixes for achieving <br />high quality and productive hayland. The recommended alfalfa varieties have done well in the region (T. <br />Doherty, personal communication, April 1988). Latar orchardgrass is a very compatible grass when used in <br />an alfalfa-grass hayland stand. Latar orchardgrass is productive, has very good nutritive qualities, and <br />reaches the most desirable harvest stage at the same time as alfalfa (Hafenrichter et al. 1979 and Heath et <br />al. 1985). <br />Upon completion of the seeding operations, lands that are to be returned as irrigated pasture may <br />be irrigated using sprinkler irrigation. The irrigation design and application rates will be submitted to CDMG <br />for concurrence. <br />Maintenance activities will include the normal monitoring forand repair of excessive tilling orgulling, weed and <br />pest control, and any necessary reseeding. The rill and gully management and stabilization plan is detailed <br />at the end of this section. Weed and pest control management will be conducted as necessary and in <br />accordance with the plan described at the end of this section. <br />Management activities will center on proper irrigation water management, fertilization, and grazing or harvest <br />management. Irrigation will be accomplished with side roll sprinklers and~water cannons supplied by 12 inch <br />and 6 inch supply lines. Water will be applied at a rate of 2 inches per week. Exhibit 2.05.4-5 shows sprinkler <br />layout to cover both irrigated pasture and irrigated hayland. Fertilization requirements will be based on the <br />results of periodic soils tests and NRCS or Extension Service recommended normal application rates, with <br />the rates directed towards maintaining vigor and the required production level of the stand during the bond <br />liability period. Split applications will be considered for maximum effectiveness of the fertilizer applications. <br />Grazing of the established irrigated pastures will not be considered during the first season in order to reduce <br />trampling and pulling ofthe plants by livestock. Harvesting (mechanical) will be used to remove any significant <br />growth during the first season. After the first season, and depending on the size of the management unit and <br />availability of additional management units, grazing may be implemented. Harvesting will continue to be <br />considered as a management option if grazing is not implemented in any given year. Harvested hay will be <br />removed from the fields as rapidly as hay quality and weather conditions permit. <br />Revegetation Methods - Dryland Pasture <br />Thedrylandpasturetypewillbeestablishedin areas which were previously sagebrush rangeland on the 1987 <br />Travessitta-Pinon soils and on 1999 soil map units 986, 98C, and 98H (see Map 2.04.9-1 ). <br />• <br />(Revised a/27/oo) 2.05.4(2)(e)-9 <br />
