Although clay soil are rich in nutrient, they are not good for most agricultural crop production because they

  1. do not release their nutrients
  2. are too compact and poorly aerated ✓
  3. lose their nutrient too readily after rain
  4. contains too much iron, aluminium and boron

Explanation

Clay particles are tiny and pack together tightly. This leaves almost no space for air to reach plant roots.

Roots need oxygen to grow and absorb water. Without air pockets in the soil, roots suffocate even though nutrients are present.

The problem is not the nutrients but the physical structure of clay soil.
