How to Make Liquid Fertilizer from Egg Shells

Most of us throw away the eggshell immediately after the contents are taken. However, did you know that the egg shells we usually throw away are a good source of nutrients for plants? 

Egg shells are a rich source of calcium and contain 2.2 grams of calcium in the form of calcium carbonate. This is twice the amount of calcium an adult human needs per day.

How to Make Eggshell Liquid Fertilizer

1. Boil a gallon of water.
2. add 10 eggshells that have been washed and dried into it.
3. For a more potent fertilizer, add 20 egg shells.
4. After that, cool and leave overnight.
5. Strain the water and separate it from the shell.
6. Water the plants with concentrated water to provide additional nutrients.
7. Fertilize once a week for best results.

Benefits of Eggshell Liquid Fertilizer

The content of calcium carbonate (CaCo3) in egg shells is very good for plants. As described in a paper in the Annals of Botany, if plants don't get enough calcium, they can experience some problems with their growth. In watermelon plants, peppers and tomatoes, for example, can cause flower rot. For leaf vegetables, leaf growth will be slow or turn brown.

Another advantage of using liquid eggshell fertilizer, there are no negative side effects for plants and for you. This is different from using synthetic fertilizers made from chemicals. You may experience poisoning or skin allergies if you use too much chemical fertilizer.

Even in plants, growth can be disrupted if the use of synthetic fertilizers is not done wisely. In fruit and vegetable harvests using organic fertilizers such as eggshell fertilizer, it can be safely consumed without worrying about residues from chemicals that stick to the surface of the plant or are absorbed during its growth period.
