"Mary, Mary, quite contrary. How does your garden grow?" She uses organic matter and fertilizers to supplement her soil, what else? Organic fertilizers, although not specifically regulated related to their composition, are essentially any organic matter that can be used as a fertilizer or soil amendment.
Organic gardeners prefer organic fertilizers to inorganic ones (those manufactured) because they are less harmful to the environment and are far less expensive. Most organic matter used to make organic fertilizer can be found in your home, thus repurposing something you would otherwise throw out.
There are almost as many recipes for making organic fertilizer as there are gardeners who use them. Many have been developed over time, and each gardener will swear by their results. One of the commonly used fertilizers is animal manure, specifically from cows or chickens. Another commonly used fertilizer is compost, which requires you to create a pile of leaves and household food scraps (like banana peels and egg shells). This pile is continually turned and mixed as it decomposes until ready to use.
People prefer organic fertilizers also because they are not adding potentially harmful chemicals to their food supply. By using materials that come from the earth naturally, they are continuing the earth’s cycle of sustaining itself.
By using organic fertilizers, you can create a better soil structure and one that has better water retention capabilities. By activating the enzymes that occur in soil naturally, nutrients from the fertilizers are absorbed more easily and your plants are better able to adapt.
