Savoy and Provin to take the lead in development of SERA publication/fact sheet on standard methods and use of estimated/calculated/Other CEC

8:30 a.m., Group discussion of our Mission and Goals, Educational role of labs as Land Grant Institutions � Kathy Moore reporting

�Motion made by Jerry Kidder and seconded by Ray Tucker: The amount of a particular element extracted from a soil is known to depend on the extracting method. Therefore, identifying the method used is important soil test information. Be it resolved that SERA-IEG-6 encourage soil testing laboratories to identify the extracting method as part of each report of soil test results.
Discussion called for... Motion/resolution approved by acclamation. To be published in a special section on our web page

10:00 a.m., Break

- Non-research forage samples steady at 14-15K. Water samples increased from 1200 to 1650.
- Heavy metal analysis suite dropped during 2000 due to insufficient sample numbers and concerns over competition with environmental laboratories.
