Weed and Pest Control <br />Maintenance activities will include the normal monitoring for and repair of excessive rilling or <br />gulling, weed and pest control. The rill and gully management and stabilization plan is detailed <br />in Section 2.05.3(3). <br />Fertilization Plan <br />Initial fertilization of Irrigated Pasture soils will take place during topsoil preparation procedures <br />as described in Section 2.05.4(2)(d) subsection 13.2. Beyond the first year of the liability period, <br />nitrogen and phosphorus will be applied to the Irrigated Pasture reclamation units. Irrigated <br />Pasture areas and the reference are fertilized at the following rates: <br />Nitrogen: 60 lbs/acre <br />Phosphorus: 20 lbs/acre <br />These rates are those recommended by the local NRCS office in Norwood, CO. <br />Grazing Plan <br />Grazing of the Irrigated Pasture will not be considered during the first growing season in order <br />to reduce trampling and pulling of the plants by livestock. If significant growth needs to be <br />removed during the first season, mechanical harvesting will be used. Grazing will only be <br />applied to the Irrigated Pasture areas after the first growing season. Following the first season, <br />grazing and/or mechanical harvesting will be used as part of the management of the Irrigated <br />Pasture areas. Harvested hay will be removed from the fields as rapidly as hay quality and <br />weather conditions permit. <br />Grazing management will be coordinated with the owner of the herd that is contracted to graze the <br />reclaimed and/or reference areas. Length of the grazing period and intensity of the grazing activity <br />(number of animals over a given area) will be determined based on previous successful grazing <br />practices on Irrigated Pasture areas on the New Horizon permit area. <br />During years in which sampling is conducted for bond release application, grazing and/or haying <br />will be deferred until after the sampling is completed on both Irrigated Pasture reclaimed areas <br />and the reference area. <br />As shown in the October 17, 2007 NRCS letter in Attachment 2.05.4(2)(e)-11, interseeding is <br />allowed in Irrigated Pasture as a normal husbandry practice. This may be utilized during the first <br />six years of the liability period. Interseeding will be conducted by use of a drill seeder capable of <br />seeding into an unprepared seedbed or by use of a broadcast seeder in conjunction with use of a <br />spring tooth harrow or similar locally available equipment, to provide for seed coverage with <br />minimal disturbance to established vegetation. The practice will be used for the purpose of <br />Page 29 May 2016 (TR -75) <br />
