Since crop year 1994, we had observed three times where the average CEC values (cation exchange capacity) were
above 20 for our soybean “Critical Observation Group”. This year’s CEC was 24.7, demonstrating the value of the extremely heavy soil having more moisture available to the soybean crop. The other two years had CEC’s slightly above 20 at the Agronology 10 Research Center at Walcott.
