THE FASTEST, EASIEST AND LOWEST COST WAY TO STABALIZE SLOPES BY HYDRO MULCH SEEDING
Hydro seeding has a neat green appearance Hydro seeding is a one step application. One person can easily hydro seed using mulch, seed and fertilizer which are evenly distributed in the sprayed material. It is fast and easy to do. Irregular areas are a breeze. Hillsides, banks and other areas that can be a problem with other seeding methods are easy to do.
JET SYSTEMS <ul><li>Jet agitated hydro seeding systems began to appear about a dozen years ago. These Seeding Systems offer fast even mixing with no moving parts inside the tank. The agitation system has two large jets on the lower left side of the tank. Inside the tank these jets are pointed up, and parallel to the outside surface of the tank. A very high volume of water and materials (up to 740 g.p.m.) shoot out of these jets creating an intense rolling action inside the tank. A fast mixing action that will mix a full load of materials in minutes. They offer wide open passages that virtually never plug. These systems have only 4 moving parts excluding the engine (an impeller that screws right on to the engine shaft and 3 ball valves). </li></ul>
Aerial Application <ul><li>Using one of the world's most powerful heavy lifting helicopters, the Erickson Air-Crane helicopter, the project called for the aerial application of wood fiber hydromulch, a polyacrylamide binder and an annual cereal grain. Using a series of 5 Hydromulchers, a slurry was prepared and loaded into the helicopter which dropped a load of 2,000 gallons each time it took off. A GPS guidance system was used to help the pilots position each slurry drop. </li></ul>
<ul><li>There are reasons hydro seeding works so well. The seed is suspended in a nutrient rich slurry. Contact of the seed with water in the machine triggers the germination cycle. The mulch layer seals in the moisture, and holds the soil in place. The seed is at an ideal depth for good results. The conditions are right to produce a lush green ground cover in very short time. </li></ul>
Hydro Seeding System simultaneously applies hydromulch, seed, fertilizer, tackifier and water. <ul><li>Experience an increase in germination rates with hydro seeding. Seed can be pre-germinated for even faster growth. One easy method is to soak the seed overnight in clear water and growth accelerators in a container </li></ul>
Seed at a rate of about 2 acres a day. <ul><li>FERTILIZER </li></ul><ul><li>Any type of fertilizer can be used. Liquid, water soluble or granular fertilizers may all be used with the system. Granular fertilizer is the most commonly used. The unit does not dissolve the granules. It will suspend them and blend the granules evenly in the mix. </li></ul>
<ul><li>TACKIFIER </li></ul><ul><li>Tackifiers are used to help hold the material in place on hillsides especially during rainy weather. Any tackifier may be used in a the system. The system can also be used to apply tackifer or a tackifier mulch mix over straw to hold it in place. </li></ul><ul><li>MULCH </li></ul><ul><li>There are two basic types of mulch. Wood fiber mulch is made from wood by-products. Cellulose fiber mulch is made from recycled news print. </li></ul>
Polyacrylamides (PAM) <ul><li>PAM is a water-soluble anionic polyacrylamide product used to minimize soil erosion caused by water and wind to decrease soil sealing by binding soil particles, especially clays, to hold them on site. </li></ul><ul><li>Permanent grassing applications can be better established using PAM as a tackifier and soil conditioner. </li></ul>
Polyacrylamide <ul><li>The organic components of polyacrylamide were </li></ul><ul><li>developed to chemically control erosive forces at the molecular level by holding soils in </li></ul><ul><li>place and ionically bonding them together to increase the particle size. The result is </li></ul><ul><li>increased water infiltration through the particle spaces and decreased erodibility of the </li></ul><ul><li>soil particles. </li></ul>
CONDITIONS WHERE PRACTICE APPLIES <ul><li>On irrigated lands susceptible to irrigation induced erosion, excluding peat soils, and where the sodium adsorption ratio (SAR) of irrigation water is less than 15; </li></ul><ul><li>On areas where the timely establishment of vegetation may not be feasible or where vegetative cover is absent or inadequate; </li></ul><ul><li>On areas where plant residues are inadequate to protect the soil surface from wind erosion; </li></ul><ul><li>On sites where disturbance activities prevent establishment or maintenance of a cover crop; </li></ul>

Many other products can be used in the mix. <ul><li>Some of the more common additives are Co-Polymers </li></ul>These are used when water may be a problem. Co-polymers hold 400 times their weight in water and slowly release it to the new seedlings. Locking Fibers (shown in photo on the right) may also be used. Locking fibers are made from crimped polyester. They will disperse through the load, and when sprayed on interlock to form a type of spray-on erosion control blanket. Other products to stimulate growth or to enhance the color may also be used.
