A great paper on the land grab rush happening together with the war:

War and Theft: The Takeover of Ukraine’s Agricultural Land “exposes the financial interests and the dynamics at play leading to further concentration of land and finance” - PDF 33 pages - February 21, 2023 - Oakland Institute”

LLM info on Ukraine agriculture:

Looking for information on Ukraine agriculture, in particular the so called “black soil”: in particular what is its composition, how deep is it and how other countries compare? Please direct me to academic sources and sites.

Here is some information on Ukraine’s “black soil” and its significance in agriculture:

  • The “black soil” (also known as “chernozem”) is a type of soil that is found in Ukraine and other parts of Eastern Europe. It is characterized by its dark color and high fertility.
  • The black soil is rich in organic matter, with a typical composition of about 4-6% humus. It also contains a high concentration of nutrients, including nitrogen, phosphorus, and potassium, which are essential for plant growth.
  • The black soil is relatively deep, with a typical depth of about 1-2 meters. This allows it to retain moisture and nutrients, making it well-suited for agriculture.
  • Ukraine is one of the countries with the largest area of black soil in the world. About one-third of the country’s territory is covered by black soil, and it is used to grow a wide variety of crops, including wheat, corn, barley, sunflowers, and sugar beets.
  • Other countries with significant areas of black soil include Russia, Kazakhstan, and Moldova. In general, the black soil region of Eastern Europe is considered to be one of the most fertile regions in the world.

Here are some academic sources and websites that you can consult for more information on Ukraine’s black soil:

  • “Chernozem: The Black Soil of Ukraine” (article on the website of the Ukrainian Institute of America)
  • “The Black Earth Region of Russia and Ukraine” (chapter in the book “Russian and East European Agriculture in the Twentieth Century”)
  • “Ukraine: Agriculture” (article on the Encyclopedia Britannica website)
  • “Soil Resources of Ukraine” (article in the journal “Land Degradation & Development”)

Here is the information formatted in markdown:

Black Soil of Ukraine: A Look at its Composition, Depth, and Comparisons

The black soil of Ukraine, also known as чернозем (chernozem), is some of the most fertile land in the world. Here’s some information to get you started:

Composition:

  • Chernozem is a dark-colored soil rich in organic matter (humus), nitrogen, phosphorus, and calcium carbonate.
  • Its specific composition can vary depending on location, but it typically contains:
    • 5-15% humus
    • 0.5-1.0% nitrogen
    • 0.2-0.5% phosphorus
    • 0.5-1.0% potassium

Depth:

  • The depth of chernozem can range from 50 cm to 1.5 meters (1.6 to 4.9 ft).

Comparisons with other countries:

的黑土 (hēitǔ) (black soil) is also found in other parts of the world, including: Russia * Kazakhstan * Parts of North America (Great Plains) * Eastern Europe (Hungary, Romania) * Northern China

Academic sources:

Additional Resources:

  • The USDA Natural Resources Conservation Service (NRCS) maintains a soil database that you can explore by location to find detailed information on specific soil types (https://websoilsurvey.nrcs.usda.gov/)

I hope this helps! Remember, these are just starting points, and you can find more information by following the citations and exploring the websites of the FAO and the USDA NRCS.

Certainly, Ukraine’s agriculture, particularly its “black soil” (Chernozem), is a topic of significant interest due to the soil’s exceptional fertility. Below, I provide an overview of Chernozem’s composition, depth, and comparisons with other countries, alongside directions to academic sources and sites for further reading.

Ukraine’s Black Soil (Chernozem)

Composition

Chernozem is characterized by its high humus content, which is the organic component made from the decay of plant and animal material. This gives the soil its distinctive black color. Its composition includes: - High organic matter: Typically 3-15% of humus. - Rich in nutrients: Especially high in phosphorus, potassium, and ammonia, beneficial for crop growth. - Mineral composition: Contains calcium and magnesium carbonates, adding to its fertility.

Depth

The depth of Chernozem soil can vary significantly but is one of the deepest fertile soils globally: - Typical depth range: From 1 to 1.5 meters, but can be as deep as 3 meters in some regions.

Comparison with Other Countries

Chernozem is not unique to Ukraine but is also found in other parts of the world, including: - Russia: Particularly in the “Black Earth” region, which rivals Ukraine’s Chernozem areas in depth and fertility. - Canada: The Prairie provinces have areas of Chernozem, contributing to Canada’s agricultural productivity. - United States: Parts of the Great Plains have similar soils. - Other countries: Include parts of the Pampas in Argentina and the Palouse region in the northwestern United States.

Academic Sources and Sites

  1. ResearchGate and Google Scholar: For academic papers on the composition and agricultural importance of Chernozem.
    • Use search terms like “Chernozem soil composition”, “Ukraine Chernozem depth”, and “global distribution of Chernozem”.
  2. FAO (Food and Agriculture Organization of the United Nations): Offers comprehensive reports on soil and agriculture that may include detailed profiles on Chernozem.
  3. USDA (United States Department of Agriculture): Provides soil surveys and reports that might include comparative analyses with American soil types.
  4. SCIENCEDIRECT and JSTOR: These platforms offer access to journals and articles focusing on soil science and agriculture.
    • Use keywords similar to those recommended for ResearchGate and Google Scholar.
  5. EURASIAN SOIL SCIENCE: A journal that publishes research on soil conditions in Eurasia, including Ukraine’s Chernozem.
    • Available on platforms like Springer or directly if your institution has access.

When accessing academic papers, be mindful that some sources may require a subscription or institutional access. For publicly accessible information, governmental and international organization websites like the FAO are invaluable resources.
