Question

Give reasons: a.Bubbles are observed when water is added to dry soil b.Water logged soil is not good for growing crops c.Its good to grow grass on open unused fields

Answer 1

Answer:

a) When dry soil is added in the water in a glass and stir it, bubbles appear. These bubbles are caused due to the air present in between the soil particles.

b) Water-logged soil presents problems when landscaping an area around ponds, streams or boggy locations. These areas lack oxygen in the soil around the root zones of the plants. The most suitable plants for this type of soil are those adapted to these conditions.

c) No, it is not a good practice to remove grass and small plants that are growing in an open, unused field because they hold the soil to prevent the soil erosion and maintain its fertility.
