A farmer observes that their crops are consistently waterlogged and show signs of oxygen deficiency in their roots after moderate rainfall. Based on the information provided, which soil characteristic is most likely contributing to this problem?

  • A: The soil is a loam, providing a balanced aeration and water storage.
  • B: The soil has an abundance of large spaces between particles.
  • C: The soil has a high proportion of clay particles.
  • D: The soil has a very low pH, inhibiting cation exchange.

Explanation

The text states: 'Soils with large amounts of clay tend to retain too much water, and when soil does not drain adequately, the air is replaced by water, and the roots suffocate from lack of oxygen.' This directly describes the scenario in the question.
