Ideas in this flowchart

  • Flooding alters soil biogeochemical processes
  • Flooding fills soil pores with water
  • Water-filled pores restrict oxygen
  • Microbes use progressively less efficient electron acceptors
  • Organic matter decomposition slows
  • Reduced forms of iron and manganese become more soluble
  • Soluble metals can reach toxic concentrations
  • Denitrification removes plant-available nitrogen
  • Denitrification produces gases such as nitric oxide and nitrous oxide

"Flooding fills soil pores with water, restricts oxygen, and causes microbes to use progressively less efficient electron acceptors. Organic matter decomposition slows, while reduced forms of metals such as iron and manganese become more soluble and can reach toxic concentrations. Denitrification can remove plant-available nitrogen and produce gases such as nitric oxide and nitrous oxide."
