11.1. Understanding Soil pH and Its Impact on Nutrient Availability

Soil pH is a measure of the acidity or alkalinity of the soil, ranging from 0 to 14. A pH of 7 is neutral, below 7 is acidic, and above 7 is alkaline. Most plants thrive in a slightly acidic to neutral pH range (6.0 to 7.0). When the soil pH is too high or too low, certain nutrients become less available to plants, even if they are present in the soil.

11.2. Ideal pH Range for Magnesium Absorption

Magnesium is most readily available to plants when the soil pH is between 6.0 and 7.0. In highly acidic soils (pH below 6.0), magnesium can be leached out, making it unavailable to plants. In alkaline soils (pH above 7.0), magnesium can bind to other elements, forming insoluble compounds that plants cannot absorb.

11.3. Adjusting Soil pH for Optimal Results

If your soil pH is not within the ideal range for magnesium absorption, you can adjust it using soil amendments:

  • To Lower pH (make soil more acidic): Add elemental sulfur, sphagnum peat moss, or acidifying fertilizers.
  • To Raise pH (make soil more alkaline): Add lime (calcium carbonate) or wood ashes.

It’s crucial to conduct a soil test before adjusting the pH to avoid over-correcting and creating new nutrient imbalances.

11.4. How Soil pH Affects Epsom Salt’s Solubility

Epsom salt dissolves readily in water, but its effectiveness can be reduced in soils with extreme pH levels. In acidic soils, the magnesium may be washed away, while in alkaline soils, it may form insoluble compounds. Maintaining the correct soil pH ensures that the magnesium from Epsom salt remains soluble and available for plant uptake.
