Too much fertilizer produces <br />a lush golf course type of effect. The new vegetation is kept slightly <br />starved to blend with the slightly starved natural vegetation. <br />Sewage sludge, in combination with wood chips, has proven to <br />be an excellent source of nutrient for grasses and trees planted on <br />rock waste at the exhausted Urad Mine (AMAX), and, if a1~ail.sble, will <br />be used as much as possible dining regetation of disturbance>_s at <br />Henderson. \ <br />9-5 <br />
