Soil Microbial Biomass and Microbial Quotient under Different Plantations at Maldeota, Dehradun, India
Abstract: Microbial properties have been reported to be useful indicators of soil quality and could serve as assessment criteria for the successful rehabilitation of ecologically disturbed areas. The microbial quotient – ratio of soil microbial biomass C to soil organic C – may, therefore, be a more sensitive parameter to monitor organic matter dynamics than either microbial biomass C or soil organic C considered alone. The study site is located at …

Efficacy of Strain Wedge Method Against Traditional p-y Method for Analysis of Piles Subjected to Different Load and Soil Condition: A Review
Abstract: Pile foundation plays a major role in design of structures as its lateral response dominates the design subjected to lateral loads. These loads acting on foundations may be sustained from traffic loading on a bridge pier or earth pressure in a retaining wall. As soil reaction and pile deflection affect each other for a lateral load, this becomes a very complex soil-structure interaction problem. There are many approaches or methods …
