3. Highly retentive of moisture, extremely compact and tenacious when wet
4. Contractible and develops deep wide cracks on drying
5. Calcareous and neutral to mild alkaline in reaction, high in carbon exchange capacity and low in organic matter
6. Self-ploughing and comparatively less fertile on the uplands than on the lowlands.
