342 - 3 Time of Seeding Time the planting of grasses, legumes and other seeded species according to Colorado Plant Materials Technical Note No. 59, Plant Suitability and Seeding Rates for Conservation Plantings in Colorado, Table 2. Up to 10 days flexibility may be allowed to adapt [o local soil moisture conditions. Fall plant species such as Rocky Mountain Penstemon, hairy vetch, milkvetch and Indian ricegrass to help break seed dormancy. Selection of Species Species recommendations shall be consistent with Colorado Plant Materials Technical Note No. 59, Plant Suitability and Seeding Rates for Conservation Plantings in Colorado, Table 6. Site-specific knowledge of the Major Land Resource Area, topography, soils, precipitation potential, elevation and future use and management is required to develop site-speck Critical Area Planting recommendations. Rates of Seeding Specify seeding rates according to Colorado Plant Materials Technical Note No. 59, Plant Suitability and Seeding Rales for Conservation Plantings in Colorado, Table 5. A completed CO-ECS-S, Grass Seeding Planned and Applied, is required to document planning and application of this practice. Mulching Critical Area Plantings shall be mulched where rapid establishment of seeded species is essential or where one or more of the following fadors are likely to cause failure of the planting, as determined by the planner. • Low or erratic precipitation • Droughty or slowly permeable sails • High soil temperatures • Erosive soils • Drying winds Seed Source Use adapted improved varieties and cultivars in the following order of preference, when available. Certfied named varieties Named varieties Common seed Certified named varieties are required for all NRCS cost shared programs. Request an exemption from the NRCS State Resource Conservationist iF certified seed is not available. If both Certfied named varieties and Named varieties are not available, common seed originating from the same general locality as the planting site may be used upon approval. Seed Analysis All seed, whether purchased or grown for personal use, will meet the following minimum standards if cost share is requested. Seed labeling, quality and testing wilt bern accordance with the Coorado Seed Law. This requires that seed be tested according to "Rules for Seed Testing" Association of Seed Analysts (AOSA) and Rules and Regulations under the Federal Seed Ad. Purity and germination tests for all lots of seed shall be less than one year old. Refer to the Colorado Mulching, 484 Conservation Pradice Standard for planning criteria and specification requirements. Cover sops or cop residues produced on site may satisfy mulching requirements 'rf present in sufficient quantities to decease erosion and conserve soil moisture. Refer to the Colorado Cover Crop, 340 Conservation Practice Standard for planning criteria and specification requirements. Planting Trees, Shrubs and Vines Plant woody species in late winter or early spring before bud burst. Keep roots moist at all times before planting. Spread roots out to as close to a normal position as possible during planting. Dig holes deep and wide enough to accommodate seedlings without bending roots. Plant stock at the same depth it was planted in the nursery, or slightly deeper. Do not plant stock shallower than it was planted in the nursery. Pack soil firmly around the roots so the seedling can not be easily pulled from the ground. Eliminate all air pockets in the soil around the roots. Apply water to seedlings immediately after planting. NRCS, CO October 2004
