Ebook "Antarctic terrestrial microbiology: Physical and biological properties of antarctic soils" brings together many of the world’s leading experts in the fields of Antarctic terrestrial soil ecology, providing a comprehensive and completely up-to-date analysis of the status of Antarctic soil microbiology. Antarctic terrestrial soils also harbor specialized ‘refuge’habitats, where microbial communities develop under (and within) translucent rocks.

In the present study, the properties of calcium carbonate mineralization and urease and carbonic anhydrase activities of Bacillus amyloliquefaciens U17 isolated from calcareous soil of Denizli (Turkey) were analyzed. CaCO3 was produced in all growth phases. Strain U17 showed 0.615 ± 0.092 µmol/min/mg urease enzyme activity in calcium mineralization medium and 1.315 ± 0.021 µmol/min/mg urease enzyme activity in Luria-Bertani medium supplemented with urea, whereas it showed 36.03 ± 5.48 nmol/min/ mg carbonic anhydrase enzyme activity in CaCO3 precipitation medium and 28.82 ± 3.

Ginseng rusty root symptoms (GRS) is one of the primary diseases of ginseng. This disease leads to a severe decline in the quality of ginseng. It has been shown that the occurrence of GRS is associated with soil environmental degradation, which may involve changes in soil microbiology and physicochemical properties.

Conserving natural capital and optimizing factor productivity in semi-arid regions has been a great challenge in achieving sustainability of the production system. Cotton-wheat and guar-wheat based cropping system plays a predominant role under evolving climatic scenarios by sustainable conservation of natural resources. In the present study, the effect of long-term zero-tillage practices on selected physico-chemical and microbiological properties was determined in different cropping system at 0-15 and 15-30 cm soil depth in Mahendergarh (Tigra) district of Haryana (latitude- 28.

The use of resource management technologies such as zero tillage, which can affect the soil properties, can restore soil health that is degrading at a rapid pace due to intensive agriculture, inefficient and imbalanced use of fertilisers, high-yielding crops, the use of heavy machinery, excessive tillage, etc. The health of the soil can be measured by the capacity of microorganisms that can act as early warning signals. To improve soil quality, zero tillage is recommended globally and has significant effects on soil microbial communities.

A field experiment was conducted during kharif 2010 under rainfed condition on red sandy loam soil to study the “Effect of farmyard manure and Biodigester liquid manure on soil microbial population and yield of rainfed maize (Zea mays L.)” at Agricultural Research Station, University of Agricultural Sciences (Bangalore), Bhavikere, Tarikere taluk. The experiment was laid out in randomised complete block design with three replications.

Soil forms an integral part of the ecosystem and at present the quality of a soil is defined not only in terms of its productive capacity, but also by taking the ecosystem into consideration. Consequently, when soil productivity has to be maximized, environmental effects must be given proper consideration. Thus the changes in soil quality caused by different types of land use must first be quantified for attaining sustainability in use and management.

The influence of Black Sea deep-water organo-mineral sediments (sapropels) on the quantities of basic for soil fertility trophic groups of microorganisms at cinnamon рseudopodzolic soil (Planosol) was investigated. The study was conducted in conditions of pot experiments with cultivating oriental type tobacco. Sapropels were added in an amount of 30 g / kg dry soil.Soil samples for microbiological analysis from rhizosphere zone of tobacco plants were taken.

The long-term application of excessive chemical fertilizers has resulted in the degeneration of soil quality parameters such as soil microbial biomass and nutrient content, which in turn affects crop health, productivity, and soil sustainable productivity. Organic manuring and Integrated nutrient management system (INMS) gained importance in maintaining the soil health and fertility.

The present investigation was carried out to assess the efficiency as well as effect of bio inoculation of free living N2 fixing bacterial strain (Azotobacter vinelandii strain SRIAz3) with N sources on enhancement of microbial properties of soil. A. vinelandii strain SRIAz3 was isolated from SRI Field (Central Farm, OUAT, Bhubaneswar) with optimum nitrogenase activity [121.09 N2-ase activity (nmole C2H4 mg-1 bacteria-1 h -1 )]. Azotobacter inoculated plots significantly influenced the microbial parameters.
