Namely, spring spraying with Banvel or <br />Tordon. This will be applied with a tractor mounted spray rig in <br />the larger areas such as the previously reclaimed area west of the <br />subject pit. Also the open pastures on the rest of the ranch will <br />be sprayed again as necessary. This year approximately 250 acres <br />were sprayed in this manner. On smaller, less accessible areas such <br />as the topsoil stockpiles I intend to use a hand held spray nozzle <br />which is fed from the tractor mounted tank. <br />Any areas which are reclaimed will be monitored for noxious <br />weed growth and sprayed accordingly. Unfortunately, it is <br />impossible to kill the weeds before they start growing. We are also <br />replanting and fertilizing in an effort to provide competition for <br />the noxious caeeds. The entire ranch is used for the grazing of <br />cattle which also is a deterrent to noxious weed growth. If you <br />have any further questions please contact me at (719) 634-4155. <br />Sincerely, <br /> <br />Robert W. Dellacroce <br />iii iiiiiiiiniiiiii <br />999 <br />RWD\Wp <br />
