<br /> <br />1. native seed mixture and green gentian seeds did not germinate <br />2. Willow cuttings did not survive. <br />3. Spruce transplanted were healthy with 100 percent survival. <br />4. All willow transplants were live, but some had yellow leaves. <br />5. Cinquefoil transplants were mostly in poor condition except for a <br />couple in good condition. <br />6. Sage transplants were in good condition. <br />9.2.6 Legume Establishment and Adaption Study on Soil and Subsoil 1976 <br />Nitrogen and phosphorus are generally the most common nutrien~;s limiting <br />plant growth on disturbed sites. Phosphorus can be applied prior to working <br />for seedbed preparation and will usually stay where it is placed and be <br />available to plants for many years. So normally only one application of <br />phosphorus is all that is required, if applied in sufficient amounts. <br />The application and maintenance of adequate nitrogen for plants on disturbed <br />land poses a much greater problem. Under native conditions, enough organic <br />matter accumulates over the years so that the amount of nitrogen cycled by <br />microorganisms is sufficient to support the vegetation. However, if an area <br />is lacking topsoil, the effect of N fertilizer is usually short-lived as <br />nitrogen can be leached and is also tied up in plant residues. <br />Legumes, if properly inoculated with appropriate symbiotic bacteria, can fix <br />their nitrogen from the air. Legumes are also high in protein, which means <br />that once the plant has died, it can decay considerably faster than grass <br />and release nitrogen to the soil. The knowledge of legume performance and <br />adaptation is limited in the upper subalpine area. <br />35 <br />
