Soil acidity

Soil acidity refers to how much the soil resists or attracts hydrogen ions, which affects plant growth. Acidic soils have a pH below 7, while neutral soils are at 7. High acidity can limit nutrient availability and harm crops, often caused by natural processes, certain fertilizers, or heavy rainfall. Adjusting soil pH with amendments like lime can improve plant health. Monitoring soil acidity helps ensure plants get the right nutrients and grow optimally.
