• retention on the newly revegetated surfaces. CEC would employ any of the following <br />amendments singly or in combination when determined to be warranted, on revegetation <br />parcels which show indications of low soil moisture or insufficient organic material. <br />Applications could be made prior to initial seeding or as a husbandry practice. <br />0 <br />Biosol <br />Biosol is a commercial organic fertilizer (6-1-3 or 7-2-3) that is manufactured <br />from the penicillium fungus mycelia, and is a byproduct of antibiotic production. <br />The advantage to this product is the slow release of nitrogen for plant fertilization, <br />stimulation of microorganism growth, and high organic content. Biosol would be <br />applied at the manufacturers recommended rate of 1000-2000 pounds per acre, <br />dry weight. When determined to be appropriate, Biosol would be applied at the <br />time of seeding. <br />Humate <br />Humate is a soil amendment, which provides additional organic matter to soils <br />through incorporation of humic acid, organic matter, and carbon. This product <br />stimulates microbial growth and is commonly used on golf courses and in lawn <br />and nursery applications. As with biosol, humates would be applied dry, at <br />manufacturer recommended rate of 500 pounds per acre. Humates would be <br />applied after seeding, where it is deemed appropriate. <br />Soilguard <br />Soilguard is a bonded fiber matrix product, hydraulically applied to the soil <br />surface. The product dries onto the soil surface, coating the surface and reducing <br />soil erosion while retaining moisture for plant germination and growth. The <br />product retains its form even when rewetted. Soilguard would be applied with a <br />hydromulcher during a second pass following initial seeding. The site specific <br />recommended application rate is 3200 pounds per acre, based on soil material and <br />slope at the Keenesburg Mine. This product will be considered for use in only the <br />most xeric problem areas. <br />Soil Binders (Co polymers) <br />Several soil binding products, comprised of organic co -polymers, exist which <br />could be applied (when determined to be appropriate) to soils to control erosion <br />and stabilize soil surfaces. These products can be very effective on sand for both <br />wind and surface water erosion. They are applied by spray from a water truck or <br />hydromulcher. The manufacturers suggested application rate for the conditions <br />experienced at Keenesburg would be approximately 55 gallons per acre. <br />115b 04101 <br />
