Soil Amendments - a number of different soil amendments were <br /> evaluated in conjunction with revegetatior test work conducted <br /> on affected acreages. In addition to determining the best <br /> plant materials for use in revegetation, it was considered es- <br /> sential to select cultural methods or application techniques <br /> which would permit maximum germination and growth rates of <br /> selected plant species to be attained. The various inorganic <br /> and organic soil amendments employed were integrated into differ- <br /> ent seedbed application methods during this phase of the testing <br /> program. Specific seedbed preparation techniques tested include: <br /> 1. Bedded furrow in which furrows were placed parallel <br /> to elevation contours and then bedded with varying amounts <br /> of peat topsoil . Seed stock was then placed in �the peat <br /> and covered. <br /> 2. Broadcast in which seed stock was broadcast straight <br /> into. existing substrate along with inorganic fertilizers to <br /> provide primary plant nutrients. <br /> 3. Straw mulch in which seed stock was broadcast on exist- <br /> ing substrate along with inorganic fertilizers. The seeded <br /> sites were then covered with straw mulch at various applica- <br /> tion rates. <br /> 4. Wood fiber mulch in which seed stock was broadcast on <br /> existing substrate with inorganic fertilizers. The seeded <br /> site was then covered with wood fiber mulch at various <br /> application rates using hydromulching equipment. <br /> Upon evaluating success rates and economics of application, <br /> two types of soil amendment routines, inorganic fertilization and <br /> Page 12 <br />
