After soil chemical analysis, obtained result for the content of organic carbon and nitrogen in kg/ha shows 0.00, whereas potassium content is 55.20 kg/ha for a surface soil sample collected in the Panagarh forest patches under the Bardhaman Forest Division of West Bengal, the soil was collected in the depth of 15 cm and the bulk density of the soil is 1.3 gm/cubic cm, visibly the sampled soil is the admixture of Alfisol and lateritic combination, is it possible for the soil sampled in the natural forests lacking both organic carbon and nitrogen, though the nature of forest vegetation is quite normal in the sampling spot?
Hi Gautam,
I strongly suspect that the values are incorrect. How was C and N measured?
It is unlikely that, at 15 cm, you would have absolutely no organic C or N present in a forest soil. I would recommend you validate the measurements. A simple test would be loss on ignition.

Yes that's I suspect, l must repeat the analysis, and this time physically I will be present, not solely depending on the lab assistant
Values could be erratic , please also ensure that sampling site not any sand deposits etc....but if that site is under the influence of forest , surely will display some values , not 0.00 to say the least...
I am agreed with the suggestions of Anoop Kumar Srivastava Sir. There may be either sampling or analysis error. The soil of forest areas contain a significant percentage of C and N.
That's why I will repeat the analysis of that particular sampled soil.
