To study the texture of soil/ Class 12th Biology practicals

Aim To study soil samples from two different sites and analyse their properties such as texture, moisture content, water-retaining capacity and pH. Also, the study aims to correlate the plants found in such soil. Necessary Materials & Apparatus For this experiment, soil collected from the roadside and garden are to be used. Apart from the soil samples, other required materials are: Tile. Beaker. Burner. Dropper. Petri dish. Glass rods water , electronic balance To study the texture of Soil Samples Collect 50 gm of any soil sample in a beaker. Take a clean and moisture-free measuring cylinder and the collected soil sample into it. Now pour little water into the same measuring cylinder and shake well. Keep the apparatus undisturbed for a few minuted and wait for the particles to settle down. After a while, observe the changes in the measuring cylinder. The soil particles in the measuring cylinder will start to settle down in layers. Record the thickness of these layers. Observation Using a soil textural triangle, draw the corresponding percentage of the soil components (silt, clay & sand). The resultant lines which, intersect indicate the type of soil. #12thbiologypracticles#Tostudythetextureofsoil#learnbiologyviapraveena
