That's not too bad.....Calcium needs some increase...shoot for 3000 ppm...Don't use Lime...it will raise the PH...use Gypsum. Otherwise your looking pretty good. Also...Kelp Meal is an excellent amendment to add every year (North American Kelp out of Maine). Mark

I see no mention of OM in your report. However from the CEC of 10.5 it must be in the lower ranges at or near normal background levels of aprrox. 5% in your Michigan area. Gypsum as stated above and lots of OM, Leaves, manure, grass clippings, yard waste and compost. For N add Alfalfa meal. Add kelp meal any time. Resist the urge to add any thing else and you'll have a fine patch in 2008.

StL Kenny and Russ: StL Kenny, I know you asked Russ to answer what CEC is... I would like to take a crack at an answer. CEC = Cation Exchange Capacity. It's a measurement of the nutrient/water holding capacity of the soil. It is a measurement of how your soil holds or binds cations like K, Mg, Ca. I'm trying to think of an analogy. Let's say you bought a 300 Amp car battery (13.2V), 300 Amps is the CEC. The full potential of the battery is 300 Amps. A 'D' battery (also 13.2V) can put out 0.5 Amps. Big difference. CEC tells you how many cations the soil can hold per 100 grams. What does it do for you?... It's a good indication of soil fertility. When the soil can't hold onto nutrients, the plant will use alot of energy searching for nutrients. Plus, nutrients will leach out. The soil will have a hard time retaining water. Greg
