RE: Too much lime?
look on your soil test and find a number that says CEC. If you give me this number I can come close to telling you what you probably moved your pH to. Personally, I hate to see anything over 6.7. 6.3 to 6.5 is more than adequate for all crops but alfalfa and you aren't going to be able to tell the difference even down to 5.8/6.0. I think the seed companies are kind of overdoing it and a lot of people are spending money unwisely. Don't get me wrong, if the soil needs it do it but the guidelines are kind of misleading.
