Methods of seeding Use a drill to plant seed on slopes that are 33 percent (3:1) or flatter. The drill must have the capability of handling the kind and application rate of seed. For broadcast applications, incorporate seed to a depth not to exceed % inch by raking, harrowing or other proven method. Plant Indian ricegrass seed to a depth of up to 2 inches on sandy loam and loamy sand soils. 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. Allow up to 10 days flexibility in seeding dates in order to adapt to 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-specific Critical Area Planting recommendations. Seed Source Use adapted improved varieties and cultivars in the following order of preference, when available. Certified 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 Certified 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 that is cost -shared, whether purchased or grown for personal use, will meet the following minimum standards. FOTG, Section IV Standards and Specifications 342-3 • Seed labeling, quality and testing will be in accordance with the Colorado Seed Law, which requires testing according to the "Rules for Seed Testing" of the Association of Seed Analysts (AOSA), and Rules and Regulations under the Federal Seed Act. • Purity and germination tests for all lots of seed shall be less than one year old. Rates of Seeding Specify seeding rates according to Colorado Plant Materials Technical Note No. 59, Plant Suitability and Seeding Rates for Conservation Plantings in Colorado, Table 5. A completed CO -ECS -5, Grass Seeding Planned and Applied, is required to document planning and application of this practice. Mulching Mulch Critical Area Plantings where rapid establishment of seeded species is essential or where one or more of the following factors are likely to cause failure of the planting, as determined by the planner. • Low or erratic precipitation • Droughty or slowly permeable soils • High soil temperatures • Erosive soils • Drying winds Refer to the Colorado Mulching, 484 Conservation Practice Standard for planning criteria and specification requirements. Cover crops or crop residues produced on site may satisfy mulching requirements if present in sufficient quantities to decrease 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. NRCS, CO November 2007
