clayey soil are useful for crops because it has very small sized particles. These particles are packed tightly and therefore can retain water. Clayey soil is also rich in organic matter. For growing crops such as wheat, gram, and paddy, the soil should be good at retaining water and rich in organic matter is suitable.
