Because the water is held tenaciously by the smectitic clay. It have low permeability and the bulk density of these soils is generally high (1.5 to 1.8 Mg m -3) because of it is shrink when it dry.

Answer 2

Hey buddy,

Here's your answer ⤵️⤵️⤵️

The clay of the black soil has an ability to expand and contract.

When the soil comes in contact with water when the field is irrigated, the clay present in the soil absorbs the water and the moisture content available.

Therefore, black soil has a great capacity to hold moisture.

Hope it helps ☺
