This file (is there a way to attach files to a post?) is from the website of the International Fertilizer Industry Association.
It is a summary of data from three older studies...
an excerpt:
Note: Plants were grown in "chernozem", which is a Russian word meaning "black soil" and is a humus rich and very fertile loamy (nutrient rich) soil found all over the word in various places typically of cool to temperate semiarid regions (ex., grasslands), it is very good soil for growing plants.
Typical nutrient profile of chernozem (Melent’ev, et al, 1999)
* Total Nitrogen = 0.61%
* P2O5 = 0.15%
* Ca = 0.049%
* Mg = 0.012%
* CEC = 15 – < 40 meq/100 g
