Soil Chemistry Fundamentals, Part 2 – How to Change Soil pH in Organic Gardening

  Most plants prefer a neutral soil around pH 6.5 to 7.5, but many will grow favourably in the broader pH range of 5.5 to 8. When soils become too acidic or too alkaline, some essential plant nutrient will become unavailable to plants, negatively impacting plant growth and yields, so it’s desirable to correct theContinue reading “Soil Chemistry Fundamentals, Part 2 – How to Change Soil pH in Organic Gardening”
