Final answer:
Healthy soil characteristics include
D. low nitrogen concentration
E. nutrient rich
F. pH between 5.5. and 7.0
Poor soil characteristics include
A. High hydronium ion concentration
B. Large amount of carbon dioxide
C. pH less than 5.5
Step-by-step explanation:
Healthy soil characteristics:
- Nutrient-rich: A soil that is rich in essential nutrients promotes healthy plant growth.
- pH between 5.5 and 7.0: Most plants prefer a slightly acidic to neutral soil pH range for optimal growth.
- Low nitrogen concentration: Nitrogen is an essential nutrient for plants, but an excessively high concentration can lead to environmental issues.
Poor soil characteristics:
- High hydronium ion concentration: High concentration of hydronium ions indicates an acidic soil pH, which may negatively affect plant growth.
- Large amount of carbon dioxide: Excessive carbon dioxide in the soil can indicate poor soil aeration and may inhibit plant root growth.
- pH less than 5.5: A soil with a pH below 5.5 is considered acidic and may have limited nutrient availability for plants.
