Understanding Soil pH and Amendment
Formula
Soil pH affects nutrient availability to plants. Most vegetables and flowers thrive in slightly acidic to neutral soil (pH 6.0-7.0). If your soil is too acidic, add lime (calcium carbonate) to raise pH. If too alkaline, add sulfur to lower it.
The amount of amendment needed depends on the pH change required and your soil type. Clay soils have more buffering capacity and require more amendment than sandy soils. Always apply amendments gradually and retest after 2-3 months.
Common use cases:
- Preparing garden soil for planting
- Correcting acidic or alkaline soil
- Blueberry bed preparation (acidic soil)
