Answer
Sanmeet
To put it simple, the soil is worn out.
This can happen when plants are grown and they take the minerals and any microbes that break down the 'food' the plants needs to grow, and nothing is replaced. This is barren soil. It would be like you setting down for a bowl of soup and an empty bowl is set in front of you. There is something to hold the soup but nothing in it.
Hope this is what you wanted to know.
