  1. The soil analysis (testing) methods described in this laboratory guide are the more commonly used methods applicable to most soil types. To assist manual users, interpretation data for analysis results are given for each method.

    • Principle:
    • Materials required:
    • Collection of soil samples from a profile
    • Processing and storage
    • ‘Remove foreign materials like roots, stones, pebbles and gravels

    Soil testing is an essential component of soil resource management. Each sample collected must be a true representative of the area being sampled. Utility of the results obtained from the laboratory analysis depends on the sampling precision. Hence, collection of large number of samples is advisable so that sample of desired size can be obtained by...

    Depending upon the purpose and precision required, following tools may be needed for takings oil samples. Spade or auger (screw or tube or post hole type) Khurpi Core sampler Sampling bags Plastic tray or bucket Copying pencil for markings and tags for tying cloth bags. Soil sample information sheet.

    After the profile has been exposed, clean one face of the pit carefully with a spade and note the succession and depth of each horizon. Prick the surface with a knife or edge of the spade to show up structure, colour and compactness. Collect samples starting from the bottom most horizon first by holding a large basin at the bottom limit of the hori...

    Assign the sample number and enter it in the laboratory soil sample register. Dry the sample collected from the field in shade by spreading on a clean sheet of paper after breaking the large lumps, if present. Spread the soil on a paper or polythene sheet on a hard surface and powder the sample by breaking the clods to its ultimate soil particle us...

    Quartering is done by dividing the thoroughly mixed sample into four equal parts ‘Two opposite quarters are discarded and the remaining is mixed Pack the collected sample ‘Label with required information

  2. Nodule position. Predominantly crown nodulation is observed when seed is inoculated. Lateral nodulation is prevalent when native Rhizobia species exist in the soil or when granular inoculants are used. The crown region of a plant is generally the area of soil surrounding the seed.

  3. This course covers laboratory test procedures, typical test properties, and the application of test results to design and construction. Symbols and terms relating to tests and soil properties conform, generally, to definitions given in ASTM Standard D653, Standard Definitions of Terms and Symbols Relating to Soil and Rock Mechanics

  4. For each test, the document describes what is measured, recommends how and when to test, indicates levels at which test results suggest deficiencies or excessive concentrations, and suggests solutions to correct soil imbalances.

  5. In-Situ Soil Testing Methods. In-situ soil testing methods are performed directly in the field to assess soil properties and conditions at the site without the need for soil samples to be transported to a laboratory. These methods provide real-time data and are crucial for geotechnical engineering, construction, and environmental assessments.

  7. Procedure to calculate moisture content in soil by Oven Drying Method. Step 1: First of all, the soil sample is collected from the site. Step 2: Then, the mass of empty can is recorded (say M1). Step 3: Then, the mass of moist soil and can is recorded (say M2). Step 4: Now, the can containing moist soil is kept in the oven for 24 hours.
