SOIL PRODUCTIVITY RATINGS
humid climate, deep soils with good water-holding
capacity, a favorable topography, and the use of improved crop-management
technology. Within the state, climate and length of
crop-growing season vary significantly depending on region. As a consequence of the variability of
climate, soils and management, differences in crop
production and soil productivity exist.
Soil productivity refers to the capacity of soil to grow crops or plants
under specified environmental conditions and is influenced by soil properties,
climatic conditions and management inputs.
The
Sources of crop yield data for validation included the following: the previously published 1970s crop, forage, and timber yields in Circular 1156, Soil Productivity in Illinois, the supplement “Productivity of Newly Established Illinois soils, 1978-1994", Illinois Agricultural Statistics Staff records (1969-1999), aggregate Illinois Farm Business Farm Management records (1976-1997), Illinois Agricultural Experiment Station agronomic research center plots (1990-1999), Illinois Experiment Station managed variety trials (1990-1999), check plots on farmer fields (1990-1999), and wide spread use of crop yield monitors coupled with global position satellite system (1997-1999) by both farmers and researchers. In addition, field measurement checks under an optimum level of management were made on 18,000 acres on 1400 parcels and included 3 to 5 years of corn and soybean yield data for 90 soil types.
Our approach to estimating yields included the development of crop yield-soil property models using stepwise multiple regression of established crop yields and soil properties, calculating the magnitude of crop yield change during the last 22 years and comparing updated yields with 1990s farmer reported crop yields on a county basis.
Current crop and forage rotations were determined for 2 soil
regions (northern and southern) in
Productivity indices provide a single scale with which soils may be rated according to their suitability for several major crops under specified levels of management. Differences in crop yield and soil productivity may be represented by soil productivity indices. The soil productivity rating is an index that ranks soils types on the basis for the productive capacity of a soil. Productivity ratings are a good indicator of the suitability of soils for crop production. They are useful in determining the best use and management of soils. Crop productivity indices are given for the various soils. A simplified method of adjusting both yields and productivity indices for slope and erosion is provided. The 1990s soil productivity indices were calculated for 786 soil types using average 1990s cropping patterns, which reflect soil conservation concerns, and yields of corn, soybeans, wheat, oats, grain sorghum and forage crops under either a average (Bulletin 810) or optimum (Bulletin 811) level of management.
Forestry productivity data and site index value estimates for 7 important tree species were developed to quantify the effects of soil properties on tree growth. Statistical models were used to quantify the relationship between soil properties and expert-derived values for tree growth. The projected productivity timber site indices will be useful to land managers who wish to allocate time and other resources to land based on the potential productivity of the site.

Copies of the Bulletins can be obtained by calling toll free 800-345-6087. The cost per copy of Bulletin 810 is $3.00 and Bulletin 811 is $2.50. They are also available in .pdf files on-line at web site http://www.nres.uiuc.edu/soil productivity at no charge. These up-to-date, on-line versions are being maintained for use by various groups including tax assessors, land appraisers, federal and state agencies, foresters and farm managers.

Karla Hanson, Past-President
Dale Calsyn, Vice-President
Charles Frazee, Treasurer
Bob Tegeler, Secretary
Gerald Berning, Chairperson Certification Board
The Council Meeting was called to order by President Lester Bushue at
Secretary's
Report - Bob Tegeler. The minutes were approved as written. Bob mentioned that one non-certified member
has not paid the dues for 2002, to date.
He will send a reminder to that member.
Bob also mentioned that membership cards have been sent to the 55
non-certified
members, who have paid their dues for 2002.
Treasurer's
Report - Charles Frazee. The
treasurer's report showed a balance of $9,158.87 as of
Certification Board - The
Executive Council approved Steve Elmer as a member of the ISCA Certification
Board. A discussion ensued concerning
the inclusion of ARCPACS Certified Soil Classifiers on the hardcopy list of
Certified Soil Classifiers, who are consulting in
Currently an ARCPACS Certified Soil Classifier
whose name is on the ISCA webpage list, was not allowed to conduct onsites in certain counties, since this individual's name
was not on the hardcopy list. Gerald Berning will contact those counties to inform them that the
individual is in fact qualified to conduct onsites. The Illinois Department of Public Health
prefers to rely on the ISCA list of Certified Soil Classifiers rather than
maintain a separate list of ARCPACS Certified Soil Classifiers. ISCA will maintain a list of Consulting
Certified Soil Classifiers, both ISCA and ARCPACS. A motion was approved by the Executive
Council to make the ISCA webpage map the primary source for the list of
Consulting Certified Soil Classifiers both ISCA and ARCPACS, who are
conducting on-sites in
Standing Committee reports
Constitution,
By-Laws and Legislative - No
report.
Ethics, Certification and
Membership - The Executive
Council received an application for membership from Jessica Kurylo. Based on the recommendation of the committee, and a review
of the application by the Executive Council; Jessica was approved as an
Associate Member.
Finance - Dale Calsyn. The members of the
committee include John Doll and Bill Teater.
A discussion ensued concerning the Webpage monthly bills. Charles Frazee has not received any bills to
date. Bob Tegeler
will discuss the monthly billing with Bill Teater; he will also determine if

pay. The Executive Council approved a
motion designating the ISCA Vice-President as the Chairperson of the Webpage AD
Hoc Committee.

State
Soil - No report. A
discussion ensued concerning a request by Chairperson Bob McLeese to merge the
State Soil Committee into the Public Relations and Education Committee, since
Drummer has been designated as the State Soil. A motion was approved by the Executive Council
to merge the State Soil Committee into the Public Relations and Education
Committee.
Technical Criteria (Key to

Chairperson. The Executive Council
approved Bruce as Chairperson. Lester
mentioned the need for coordination of technical criteria between states. Gerald
Berning mentioned that the committee received
