Soil pH is a measure of soil acidity or alkalinity, which affects nutrient availability and plant growth.
- Acidic Soil (pH < 7) - Common in high rainfall areas, affects nutrient availability.
- Neutral Soil (pH 7) - Optimal for most plants, balanced nutrient availability.
- Alkaline Soil (pH > 7) - Common in arid regions, can limit certain nutrients.
- Optimal Range - Most crops prefer pH between 6.0 and 7.5.
