Abstract Information :
GC-MS can play a very important role in the micro analysis of the soil (involving agricultural practices for food crops, commercial crops, solid waste disposals, storage of soil waste and safety aspects of solid waste dumps). This analytical method can provide the information at higher accuracy even up to nano concentrations. The GC-MS 7985C Agilent make instrument is a sophisticated instrument of its kind used for analysis of the soil samples. In the present study Urea penetration in soil from top layer to a depth of 20Cms deep into the soil in presence of a crop mainly pulses and cereals which improve the N-level in the soil is studied. In the present study as a function of the parameters Retention time, temperature, peak area of the chromatogram and vegetation layer/canopy are analyzed for the Urea manifestation in soil layer. About 10 common constituents how applied Urea is manifested in the given soil samples are identified as Dimethylfluoroamine, 1,3,5-Cycloheptatriene, 1,5- Hexadiyne, 1,3,5,7-Cyclooctatetraene, Phosphoryl fluoride, (E)-1,1-Difluoro-2- ethylidenecycopropane, 1,6-Heptadien-3-yne, 5-methyl-, Deltacyclene, Boric acid, trimethyl ester, and Benzene,1-ethyl-4-methyl- groups. Another major application of soil analysis through GCMS comes out to be soil contamination in case of excessive usage of pesticides also. In all the probability the present study is a proto-type study which describes how to use GCMS analytical technique in soil sample analysis.
