ACIDS AND BASES:

Acids and bases are regularly used in the home and garden. Here are some examples of how they can be used: Acids: Bases: Explain why an understanding of pH is particularly important to gardeners and farmers. It is important that gardeners and farmers have an understanding of pH levels as soil pH levels can have a dramatic effect on nutrient availability. pH testing on soils may indicate an imbalance of the pH levels. These indicators include:
 * Wine – cooking/drinking
 * Lemons – cooking/eating
 * Vinegar – cooking/eating
 * Baking soda – cooking/cleaning
 * Coffee – cooking/eating
 * Soap – cleaning
 * Plants not performing well, even with the addition of fertiliser
 * Iron deficiency
 * Flowering hydrangeas (blue flowers are produced in soil with a pH of 6 or less and pink flowers are produced in soil with a pH of 6.8 or over)
