It’s good to know that eggshells contain 93% calcium and 1% nitrogen, making them a vital addition to the soil.
In addition, eggshells can also help maintain a balanced soil pH. It’s important to keep in mind that eggshells must be dried and cleaned before using them as fertilizer to prevent the growth of bacteria or fungi.
However, be careful if you add them in large quantities; they can change the soil’s pH, making it more basic.
