organic material provides nitrogen for plants. which soil component contributes the most nitrogen to plants?\n○ clay\n○ humus\n○ sand\n○ silt

Answer

Brief Explanations:

To determine which soil component contributes the most nitrogen to plants, we analyze each option:

  • Clay: Primarily a mineral component, holds nutrients but isn't a main nitrogen source from organic matter.
  • Humus: Decomposed organic material, rich in nutrients including nitrogen, providing it to plants.
  • Sand: A mineral particle, has little organic content or nitrogen contribution.
  • Silt: Mineral - based, like sand and clay, not a primary nitrogen source from organic matter. So, humus is the soil component that contributes the most nitrogen to plants.

Answer:

B. humus
