Observation:
The experiment will test soil samples from different locations. The pH indicators will change color based on acidity/alkalinity, and nutrient levels will be displayed.
Soil Science Principles
1. pH Importance:
Soil pH affects nutrient availability to plants. Most plants prefer slightly acidic to neutral pH (6.0-7.0).
2. Macronutrients:
Nitrogen (N), Phosphorus (P), and Potassium (K) are essential primary nutrients for plant growth.
3. Soil Types:
Different locations produce different soil characteristics affecting water retention, drainage, and fertility.
