Soil is the largest pool of terrestrial organic carbon in the biosphere and interacts strongly with the atmosphere, climate and land cover. Remote sensing (RS) and geographic information systems (GIS) were used to study the spatio-temporal dynamics of croplands and soil organic carbon density (SOCD) in the Sanjiang Plain, to estimate soil organic carbon (SOC) storage. Results show that cropland...

The present investigation is an account of soil quality parameters and wheat (Triticum aestivum HD-2285) yield as influenced by insitu incorporation of paddy straw and its subsequent inoculation with two cellulolytic and one lignolytic fungi. Such information may prove useful to farmers as it may provide them with an option to use the undesired crop waste as partial replacements for synthetic f...
