Organic fertilizer from your kitchen to the garden

Many of us follow organic methods of gardening. Here are a few tips that we use at home for fertilizing our plants using organic methods.
Chickpeas/Channa is a legume that is used a lot in Asian-Indian cooking. It is usually soaked overnight before it is cooked. We usually add a teabag to the container in which it is cooked. My husband says that it enhances the color and flavor of the chickpeas.
Once cooked, the water is drained and discarded.
But did you know that this water is rich in nutrients and fertilizes your plants?
Let the liquid cool to room temperature, dilute with some water and pour at the base of your veggie plants. This is a natural fertilizer.
The same thing can be done with water in which eggs have been boiled. Cool this liquid to room temperature..add some water and pour it at the base of tomato and pepper plants. Calcium in the water in which eggs r boiled will prevent Blossom End Rot on tomatoes. I usually crush eggshells also and add to the soil along with the water.
Many of you might already be doing this.
