4. Soil improvement
In addition to calcium, eggshells contain small amounts of other essential minerals such as magnesium and potassium. When eggshells are crushed and mixed into the soil, they improve its structure and provide your plants with these vital nutrients. Over time, this can lead to healthier and more productive gardens.
5. Compost additive
Eggshells are an ideal addition to your compost pile. Their calcium content balances the acidity of many kitchen wastes, contributing to a more neutral pH in the compost. The calcium also supports decomposition and enriches the resulting compost with valuable nutrients.
6. Natural pH regulator
If your garden soil is too acidic, crushed eggshells can help raise the pH. This is particularly beneficial for plants that prefer a more alkaline environment. By incorporating eggshells into the soil, you can create a more balanced and suitable growing environment for your plants.
