Question
How can sequencing of carbon in a peatland be determined?
Carbon biomass in a peatland plays an important role in the ecosystem as well as in the productivity of that area. To sequence the carbon is important to determine the amount of carbon in that area. What techniques/methods can be applied to determine carbon amount in a peatland ecosystem?

Wouldn't one use a method similar to that for the determination of total organic carbon in soil samples? The dichromate method or something similar. -

Hi, Arshad.
The TOC method by EPA is good for quantification, as discribed by our colleagues.
But if you wanna get qualification data, I suggest EPR for organic free radical from humic acid, besides FTIR, RMN, and UV-Vis - see Stevenson, 1994: Humus Chemistry - Genesis, Composition, Reaction (Wiley). -
In general, I find the suggestions offered above to be quite adequate. Other good resources are:

Thank you all distinguished scholars and researchers for helping me out in this topic.....

I wish to add that although you will have to employ complete block design in sampling and analysis, you should try and condense the sampling sites and have as many as possible so that when you will be cleaning your data for outliers you will remain with substantial data to anlyse. Consider also core sampling if you intent to answer your sequencing objective. Time of sampling is also vital and hence it should be consistent at all sampling points. Keep in mind that decomposition processes release carbon dioxide and the activity has an optimal temperature. Otherwise the methods stated above are sufficient enough to generate data.

In my opinion, carbon as such in peat lands, play a minor role, relative to productivity.
The quality of the NOM in these relationships is depending on pH, humidity, temp., content of micro nutrients etc. -
Egil Gjessing ! thank you for your comment... but sir, would you please explain what other factors are important for productivity in peat lands? and what is the significance of carbon in any plant productivity in any grassland or forest ecosystem?
