- Chernozem is another name for black soil.
- It is largely composed of humus, phosphoric acid, phosphorus, and ammonia.
- Exceptionally small or clay-like particles constitute black soils.
- Deep gaps form during warmer weather, resulting in appropriate aeration.
Black soil characteristics include:
- It is extremely fertile and has a clay-like texture.
- At 25°C, the pH of black soil ranges from 7.2 to 8.5.
- The soil has high levels of potash, calcium, and magnesium but low levels of nitrate and phosphate.
- It is often soft when damp but hardens as it dries.
