Yes, black soil is generally very fertile. Its high fertility is due to several factors, making it ideal for agriculture and producing high yields.
Why is Black Soil Fertile?
Several characteristics contribute to the fertility of black soil:
-
High Moisture Retention: Black soils have a remarkable ability to hold water, providing consistent moisture for plant growth, even during drier periods. This is highlighted in several sources mentioning the "high moisture-storage capacity" of Chernozem, a type of black soil (Wikipedia, Chernozem - Wikipedia). This characteristic is also noted in the reference describing Bartlett's Houston Black Soil (Bartlett's Houston Black Soil Is Once Again Fertile Ground).
-
Rich in Nutrients: While often deficient in nitrogen and phosphorus, black soils are typically rich in essential minerals like iron, lime, calcium, potassium, aluminum, and magnesium (Black soils are extremely fertile). This mineral composition supports healthy plant growth. The increased organic carbon content in some black soils, such as Terra Preta, further enhances nutrient availability (Charcoal makes African soil more fertile and productive).

Examples of Fertile Black Soil: The fertility of black soil is evident across various regions. Ukraine's Chernozem is renowned for its high fertility (What's so special about Ukraine's black soil?), and the Black Belt Prairie in the US is named for its dark, fertile soil (Black Belt Prairie). Even the Amazonian Terra Preta, a man-made black soil, demonstrates the potential for high fertility through indigenous practices (Ancient Amazonians intentionally created fertile “dark earth” | MIT ...). The fertile black soil of North Karnataka in India also demonstrates high agricultural productivity (Kripal Amanna - The fertile black soil of North Karnataka... | Facebook).
Conclusion
Black soil's fertility makes it highly suitable for agriculture, supporting thriving crops and contributing to high agricultural yields globally.
