,~ <br />i <br />J <br /> <br />n <br />Soil Testing <br />154 <br />HIGH ALTITUDE 1tEVF:GETATION <br />DISCUSSION <br /> <br />There is no question that soil testing can be as useful a tool <br />in high altitude revegetation programs as it has been in crop produc- <br />tion for many years. As additional research is conducted its poten- <br />tial (and limitations) will become clear. Certainly research <br />directly calibrating soil tests with the diverse growing situations <br />in high. altitude revegetation is important. Attempts are made too <br />frequently to extrapolate information (fertilizer recommendations) <br />developed with other cropping systems. Many problems unique to high <br />altitude revegetation may not be considered and important elements <br />(nutrients or toxic elements) may not be determined by such an <br />approach. The very fact that there have been three High Altitude <br />Re vegetation Workshops held at CSU testifies to the unique p~.ohlems <br />encountered and being dealt with, in this 'area. ~' ' <br />QUESTION: How does one communicate with the soil test lab and <br />explain needs? <br />U1IJ:JICX: Forms are available from the lab; a telephone call or a <br />detailed letter explaining your special situation is helpful. If <br />you will be sending in several samples, get to know the director of <br />your lab so he becomes familiar with your situation. The information <br />sheet should be completely filled out and be especially sure to <br />indicate the specific use of the area. For example: do not just <br />write "grass" Far the plant to be grown. A grass hay field is vastly <br />different from a lawn. For further information write: <br />Dr. P. ~. Soltanpour, Director <br />C.S.U. Soil Testing Laboratory <br />Vocational Education Bldg. <br />Colorado State University <br />Ft. Collins, Co 80523 <br />or call Dr. Soltanpour: 303-491-5061 <br />ib <br /> <br />
