Fungi have diverse biotechnological applications in, among others, agriculture, bioenergy generation, or remediation of polluted soil and water. In this context, culture media based on color change in response to degradation of dyes are particularly relevant; but measuring dye decolorisation of fungal strains mainly relies on a visual and semiquantitative classification of color intensity changes.

Nine typical pedons representing major quartzite-schistose landscape in tropical ecosystem of Goa viz., high hills, restricted summits, low hills, inter-hilly valley and narrow valley under varying land use were studied for their morphological characteristics, physical and chemical properties, soil genesis and taxonomy. The soils were slightly to moderately acidic in reaction, very shallow to very deep. Texture of the soils varied from gravelly sandy clay loam to gravelly clay on the hills and sandy clay loam to clay in valley soils.

This microbial consortium degraded 2,537.34 ngTEQ/kg of 2,3,7,8-TCDD congener in soil, equivalent to 59.1% lost of total toxicity in comparison to the control without bacterial seeding (4,294.12 ng TEQ/kg). Such a high ratio of dioxin degradation by a bacterial consortium was reported here for the first time, contributing more evidences for convincing the successful dioxin bioremediation of “Active Landfill” technology at large scale in Z1 area at Bienhoa airbase, Dongnai, Vietnam.

Taxonomical Classification, Characterization and Mapping of BSP Farm (Khanapur Block-B) for Rational Land Use Planning, MKV, Parbhani was carried out during the year 2012. The total gross area of college farm is spread over 135.49 ha and it is divided into four blocks viz. Block A, B, C and D. These four blocks were surveyed by traversing along the bunds of farm plots and the data on natural resources were collected. From these 110 soil samples were drawn to study the properties and nutrient status.

An investigation was carried out in the Bahour commune of Pondicherry with a view to characterize the ground waters and characterization of irrigation water to develop management strategies to overcome the effect of poor quality water on soil and crop growth. Water samples were collected from 100 randomly selected wells during the summer seasons of 2010 - 13 and analyzed for their ionic composition.

Six typical pedons from mulugu division of warangal district were studied for physical, physico-chemical and chemical properties of the area. The soils were moderately deep to very deep, very dark brown to strong brown in colour, gravelley sand to clay in texture and had varied structure including single grain, granular, sub-angular blocky and angular blocky. The clay content in soils varied from 1.4 to 67 per cent. The clay content increased with depth in all pedons. Silt fraction in the soils 6.7 to 32.6 per cent. The sand content in the soils under investigation varied from 8.2 to 80.
