Résumé partiel
The present investigation “Organic carbon mapping of Agro-ecological zones of Marathwada region of Maharashtra state” was carried out during 2009 to 2012 .A comprehensive study encompassing 22 soil profiles (Identified soils series) and 330 surface soil samples were evaluated for various soil properties. The soil samples collected during profile studies and surface soil samples were analyzed for various physical and chemical properties and soil carbon parameters. From the data, carbon to nutrient ratio was calculated and results are presented in previous chapter. Further from the analyzed data the soil organic carbon maps are generated and presented. The soil site suitability of important crops of region was also judged. It was aimed to study the organic carbon content in varied soil series and surface soils of agro ecological regions of Marathwada. To evaluate the physical and chemical properties and dynamics of nutrient status of soils of Marathwada region to find out relationship between C:N, C:P, and C ;S ratio and soil properties under varied agro ecological regions of Marathwada.to prepare maps of soil organic carbon status and to study the cropping pattern and land use of agro ecological region of Marathwada. The results showed that the soils of Marathawada region are very shallow to very deep, clayey, sub angular blocky, very dark gray brown to black. Taxonomicaliy these are Lithic Ustrorthents, Typic Ustrothrents, Vertic Ustochrepts and Typic Haplusterts.
