Again it is a metric measure and I dont know how to convert it
PH 6.5
Olsen P 99
CEC me/100g 27
calcium me/100g 15.6
magnesium me/100g 3.82
potassium me/100g 2.42
sodium me/100g 0.33
Base Saturation percent Ca58.5 Mg14.3 K9.1 Na1.2
Organic Matter 14.6

Any help or ideas would be good or how to convert it over to measure used in the States so I can compair it easier
There was 15 meters of chicken manure applied 5 months ago
over an area of 1800 sq feet

I'll try to convert this over when time permits.

I have no clue on what the numbers actually mean so I'll leave that up to Steve and the other soil gurus, but I can do the conversions for you.

I believe CEC is normally given in meq/100g so I'll leave that alone.

Calcium: 15.6 meq/100g = 3120 ppm
Mg: 3.82 meq/100g = 462 ppm
K: 2.42 meq/100g = 944 ppm
Na: 0.33 meq/100g = 76 ppm

Hope that helps.

Wow. If Brian's conversion is correct then there is little more to do than start seeds & grow.

If we wanted to nit-pick:

The Ca:Mg ratio could be higher. So if you have access to Caclcitic (not Dolomitic) Limestone then applying 50 lbs per 1000 tilled 6-8" down will raise the pH a little & deliver the higher ratio we'd rather be seeing. Though this isn't entirely necessary.

Tremor why not the dolomitic Limestone ?

whats the difference between the 2?

From my soil tests I was told to till in some limestone this fall along with some Composted Manure only stuff I could find was Fafard Granular Limestone in the 15 KG bags
I double dug my entire patch , first was 1.5 foot down and i layered it in limestone tilled then piled the dirt back on top and tilled in more limestone, over the next couple of weeks I'll continue to till in more manure / leafs, coffe grounds egg shells ect. Then come April I'll send another sample in to see what my numbers are at.

My PH is pretty low and i was told limestone would raise it.

just wondering what the difference was bewteen the 2 you mentioned

thanks

Dolomitic Limestone is great where Magnesium is needed becuase it's 40% Mg by weight. So while a ittle more Mg isn't going to slam his soil, there isn't just cause to add more at this time.
