	Benefits Use of Hydropost on parent material, degraded soils or harsh sites provides an environment that supports soil microbiology and sustains long term vegetative cover. Hydropost allows the establishment of native vegetation without encouraging weedy annual vegetation. Hydropost helps establish a sustainable nutrient cycling system. Biological Benefits Increases Soil Microorganisms   Beneficial Bacteria, Protozoa, Actinomycetes and Fungi Provides Plant Disease Resistance   Suppresses Pythium, Fusarium Wilt and Nematodes Provides Humic Acids   Numerous Nutrient and Soil Benefiting Properties Physical Benefits Improves Soil Structure Improves Friability and Porosity Increases Air and Water Permeability Reduces Bulk Density Increases Water Holding Capacity Improves Soil Aggregation Chemical Benefits Average Total Nutrient Content Percent Fraction Nitrogen 1.65 P Phosphorus 0.75 P2O3 Phosphate 1.50 K Potassium 1.30 K2O Potash 1.50 S Sulfur 0.35 Mg Magnesium 0.60 Cc Calcium 1.60 Na Sodium 0.35   Parts Per Million  Fe Iron 16500 Al Aluminum 15000 Mn Manganese 225 Cu Copper 125 Zn Zinc 200 Physical Properties Bulk Density 1000 lbs/yard Moisture H2O Content 35% Dry Matter Fraction 75% Organic Fraction 50% Mineral Organic Fraction 50% Humic Acid Content 1%         Increases Cation Exchange Capacity   Holds on to Nutrients, Reduces Leaching Modifies and Stabilizes pH Provides Macro and Micro Nutrients   Slowly Available, Long Lasting Hydropost provides raindrop impact and overland water flow protection Formulated for dry or wet installation. Dry application for equipment accessible sites and Hydro-application for steep or inaccessible sites allows for cost-effective placement. Specification Hydropost shall be a compost product produced by the controlled biological decomposition of organic matter that has been sanitized through the generation of heat and stabilized to be beneficial to plant growth. Compost shall be derived from chipped, shredded or ground vegetation or clean processed wood products, and a Class A, exceptional quality biosolids compost, as required by US EPA, 40 CRF, part 503c regulations. The compost shall be processed to reduce weed seeds, pathogens and deleterious material and shall not contain paint, petroleum products, herbicides, fungicides or other chemical residues that would be harmful to plant or animal life. Other deleterious material such as glass, plastics, metal or rocks shall not exceed 0.1% by weight or volume, and shall be of such size as not to harm application equipment or hinder the application of these materials. A minimum of 135° internal temperature shall be maintained for at least 15 consecutive days during the composting process. The compost shall be thoroughly turned a minimum of five times during the composting process, and shall go through a minimum 90 days curing period after the 15 day thermophilic compost process has been completed. Hydropost shall be screened through a minimum 1/4 inch screen. The moisture content shall not exceed 35%. Application per Acre Hydroseed 1-Step Method Apply seed, 500 lb. fiber, 1500 lb. Hydropost, water and tackifier as needed. 2-Step Method Step 1 Apply Seed, 450 lb. Hydropost, 150 lb. fiber. Step 2 Apply 1050 lb. Hydropost, 350 lb. fiber, tackifier, fertilizer and water as required. 2-Step method puts seed in contact with soil and protects it from predators. Higher rates of Hydropost can be used for additional nutrient or mulch. Use 3 parts Hydropost to 1 part wood or cellulose fiber. Drilled Seed Hydropost can be spread and incorporated as a soil amendment on the seed bed, spread immediately prior to drilling seed, or applied as tackifier to control wind erosion, or with tacked straw, as specified above. Hydropost Soil Amendment Incorporated into six inches of soil per 1000 square feet: 1/4 inch = 2% organic matter (low) ............ 0.75 cubic yard 1/2 inch = 4% organic matter (medium) ......... 1.50 cubic yard 1 inch = 8% organic matter (excellent) ...... 3.00 cubic yard Hydropost Plant Hole Amendment Approximately 25% by volume. 12" by 18" hole = 0.25 cubic feet 18" by 24" hole = 1.00 cubic feet 18" by 36" hole = 1.30 cubic feet Hydropost Plant Basin Amendment One inch depth. 24" basin = 0.25 cubic feet 36" basin = 0.50 cubic feet 48" basin = 1.00 cubic feet
