Also, the study aims to correlate the plants found in such soil.
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.
For this experiment, soil collected from the roadside and garden are to be used. Apart from the soil samples, other required materials are:
The following are the steps taken to prepare the soil samples for experiments to analyse various properties.
When the universal pH indicator is added to the test tube containing the soil solution, the colour changes. These colour changes can be tracked using the pH colour chart. Roadside soil has a pH level of 7 while garden soil has a pH level of 6. Most crops grow between pH levels of 6.0 and 7.0.
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.
The sample where the initial and final weight is the larger indicates a higher moisture content. Lower values mean the moisture content is quite low.
The water holding capacity of the soil is determined by the quantity of water held by the soil sample versus the dry weight of the soil sample.
