Amendments of the soil should be based on the
- type of plant
- plant nutrient requirement
- soil analysis results (i.e., chemical, physical, and biological properties).
Process/Skill Questions:

- What are the differences between chemical, physical, and biological properties of the soil?
- Why is knowledge of a plant species important when making nutrient recommendations?
