I did spend some time today searching for any information indicating that o=
rganic (sequestered) nutrients contained in compost or soil can be reveale=
d by typical laboratory testing,[not painstaking heating and weighing, etc.=
for each nutrient] including Mehlich III processes. I am willing to learn =
if I'm incorrect so if anyone has some citations, etc. please post them
Following is a not bad read and an excerpt;

"Nitrogen is present in the soil in a variety of forms that change from one=
to another (see the Nitrogen Cycle section). This has caused the limited u=
se of soil N analyses throughout the world. Most of the N present in agricu=
ltural soils is in organic forms yet plants largely feed on inorganic N, pa=
rticularly nitrate. Nitrate can be readily measured in soils, but the amoun=
t in the soil at any one time may not indicate how much is available to pla=
nts through the growing season because substantial amounts of inorganic N c=
an be released from the organic forms (a process called mineralization). Un=
fortunately, the rate of release of inorganic N from the organic matter in =
the soil cannot be predicted by a chemical analysis at this time."
