C-1981-008 <br />PR-06 PAR <br />22-Jan-2010 <br />Page 14 of 26 <br />potential cropland will be reclaimed with stockpiled topsoil. NRCS has indicated that <br />they have observed significant production benefits on depleted croplands from <br />incorporation of manure. It may be the case that stockpiled cropland soils would benefit <br />from manure incorporation. <br />Please consider including manure incorporation at MRCS recommended rates as an <br />additional practice associated with cropland soil replacement. Use of the practice <br />on a relatively small area initially on a trial basis, would be acceptable. <br />Rule 2.05.4(2)(e) Revegetation <br />44. In the first paragraph of sub-section 4.0 in Section 2.05.4(2)(e), on page (e)-19 of the <br />Redline text version, narrative indicates that companion crops of annual grains would not <br />be used during establishment of irrigated stands. NRCS has indicated that planting a <br />companion crop of oats or other small grain is an accepted and recommended practice for <br />establishment of irrigated alfalfa. A low seeding rate of 20-30 lbs/acre is recommended. <br />Please amend the narrative as recommended, for irrigated alfalfa plantings. An <br />additional footnote should be added to Seedmix #2, indicating that if any one of the <br />component species listed is seeded as a companion crop with irrigated alfalfa, the <br />seeding rate would be 20-30 lbs/acre for the companion crop. <br />45. The 4"' paragraph in subsection 4.9, on page (e)-27 of the Redline text version states <br />"...lands that are to be returned as irrigated pasture may be irrigated using sprinkler <br />irrigation. The irrigation design and application rates will be submitted to CDMG for <br />concurrence". These statements imply that irrigated pasturelands might or might not be <br />irrigated, and further that information regarding design and rates would be submitted at <br />some future unspecified time. We presume that the first statement was intended to allow <br />for irrigation methods other than sprinkler irrigation in some situations, and that the <br />second statement is an outdated relic. A summary of irrigation methods and reference to <br />supporting calculations for the irrigated cropland on the Morgan property is provided in <br />the final paragraph of the section, however no such summary or reference to supporting <br />calculations and layout is provided for irrigated pasturelands. <br />Please clarify and update the language regarding irrigated pastureland irrigation, <br />and provide a summary description and a reference to supporting calculations and <br />layout comparable to that provided for Morgan property irrigated alfalfa cropland. <br />46. Seedmix #8 for Dryland Pasture contains some errors; the individual species seeding <br />rates do not add up to the 5.91bs/acre PLS indicated. Also, we would recommend <br />inclusion of an additional rhizomatous grass to replace smooth brome, which was <br />previously removed from the mix because it is not adapted to dryland plantings in the <br />Nucla area. We recommend inclusion of the native species western wheatgrass (Arriba <br />cultivar). Recommended PLS seeding rates (lbs/acre) are listed below to achieve the <br />standard 20 PLS seeds per square foot rate previously recommended by NRCS.
