    Black soil is highly retentive of moisture, swelling when wet and cracking when dry. It's highly argillaceous with a large clay factor and lacks gravel or coarse sand. Black soils on uplands are of low fertility but become darker, deeper and richer in the valleys, so all three statements are correct.
