• <br />is to plant a diverse seed mixture into the spoil materi~il taking <br />care to include species that in total represent a wide s~~ectrum of <br />adaptation and tolerance curves and including a good nitrogen <br />fixing species that can survive in the soil texture. Thfa latter <br />(finding a good nitrogen fixer) is often the most difficult <br />aspect of the whole process and unfortunately is also a F~rimary <br />key to success. The site is fertilized to provide a good nutrient <br />level for vigorous seedling growth. Subsequent fertilizeitions are <br />done as needed to sustain a relatively high yield. Overi`ertilization <br />to produce heavy growth for appearance sake is as harmful as <br />not keeping the growth at a steady pace by underfertiliz<ition. <br />The course of events when this is done must be closely <br />J <br />followed and at various times quick action must be taken to put <br />the development back on track. The normal sequence of events occurs <br />something like this. The first two to three years the plants <br />become established and generally have a sparse density. In the <br />fourth to seventh years the grass in the vicinity of the <br />nitrogen fixer becomes noticeably larger and the growth i.s <br />accelerated as localized nitrogen cycling begins. In fire to <br />15 years, depending up the moisture regime, the ground becomes <br />well vegetated and reaches the carrying capacity for the land. <br />The key indicators that the process has worked and is <br /> <br />working on any particular site rests in two aspects. First, the <br />grass near the nitrogen fixers should be more vigorous tran <br />grasses growing away from those plants <br />And second, there should <br />S-I-10* <br />
