Question

1 . Differentiate between clayey soil and sandy soil based on its uses and
properties.


2. A soil sample takes 45mins to percolate 900ml of water. Calculate
the rate of percolation.​

Answer 1

Answer:

Here are your answers!

Explanation:

(1) Soil contains air

The large spaces between sand particles are filled with air. Due to this, sandy soil provides much more air to the plant roots. Clay particles (being much smaller) pack tightly together leaving little space for air. So, clayey soil provides much less air to the plant roots which grow in it.

Sandy soil is usually dry, nutrient and fast draining. It is used for plowing, planting and cultivating. The useful vegetables like potatoes, grams, tomatoes, etc require a minimum percentage of soil for a specific period.

(2) Percolation rate equal to amount of water / percolation time

900/45 equal to 20 . Answer is 20.

Explanation:

1।Soil contains air

2।percolation rate=amount of water(mL)/percolation time(min)

Percolation rate=900mL/45 min

=20 mL/min☺️
