In this article we will discuss about how to determine the shear strength of soil. Shear Tests: The shear strength parameters (c, ɸ) are determined under definite test conditions. Depending upon the drainage conditions, three types of shear tests have been developed. They are: (i) Unconsolidated undrained test (or simply undrained test) UU- No drainage of pore water is allowed [...]
In this article we will discuss about how to determine the nutrients present in soil. The real value of soil testing is in finding out the information about the available nutrients present in the soil. The collection, preparation and storage of the sample represent the most significant steps in entire analytical operation. The soil samples, received through the farmers or [...]
Relative density of cohesionless soils is defined as the ratio of the difference between the void ratio of a cohesion- less soil in the loosest state and in-situ void ratio to the difference between its void ratios in the loosest and the densest states. Thus relative density (Dr), also called density index (Id), is defined by – Dr = [(emax [...]
