Lime Zone and CCE

[kabic]

Is there any relation to Lime Zone and CCE? I ask because Waukesha Lime seems to report Lime Zone.

Also this publication talks about lime receommendation being for Lime Zone 60-69 and how to convert the recomdndation when using product of a differnt Lime Zone

It's basically a different way of saying the same thing kabic.

I suppose a guy could label "Lime Zone" as "calcium effective equivalent range" as well.

Thanks that some what answers my question It seems be some formula of CCE and particle size




The reason I was thinking about this, in my small plot earlier in the year I put down:
3 50# bags Pelletized lime ($6.75 each, $20.25 for 150 #total)
10 50# bags of bags of barn lime for $1.98 a bag. (500 # for $20)

The pelletized was a lot easier to spread because I could use my tow behind broadcast spreader. The barn lime was more of a manual process. At the moment I feel the price difference may be worth the extra effort even though the barn lime is lime zone 50-59 because 3 bags of that is still more than 1 bag of the pellatized.

I know I could get the pelletized cheaper if I can plan ahead and get it on sale, but I don't always do the best at planning ahead.

Here is an explanation for those new to this. If your lime source is "Lime Zone" 70-79, they are assuming the lime has approximately 75% of the neutralizing affect of pure calcium carbonate. Thus, if they recommend 1,000 lbs of actual calcium carbonate per acre, you will need to apply 25% more of the 70-79 grade lime to get the actual 1,000 lbs of calcium carbonate. So to get the true 1,000 lbs on your plot, you must then apply 1250 lbs of the 70-79 lime.

The above does depend a bit on your soil testing lab though. Some give recommendations assuming 100% CCE lime, others may specify the actual liming rate using one of the other "lime zones", so pay attention to your test recommendations and if you have questions, many here can help answer them.
