(Q.5) B) Write an experiment to prove that clay soil has a greater capacity to hold water than other type of soil.
Answers
Answer:
Soil water-holding capacity is the amount of water that a given soil can hold.
The water holding capacity of sandy soil is less compared to clay soil.
The clay soil has the highest water holding capacity and the sandy soil has the least; clay > loam > sand. Clay particles are so tiny and have many small pore spaces that make water move slower (the highest water holding capacity). Sandy soils have good drainage but low water and nutrient holding capacities
Answer:
Objective: To prove Clay soil has a greater capacity to hold water.
Materials Reqd: Clay soil, Any other kind of soil like- Sandy soil and water and a dropper.
Theory: Clay soil has fine particles compared to any other soil and so the particles bind soil with water.
Experiment: In a glass bowl, keep balls of Clay soil and in other keep sandy soil. Drop water droplets in the soil balls. The sandy soil would be runny while the Clay soil will be moist.
Hence, proved Clay soil has greater capacity to hold water.
