They are what they eat
We all know the old adage “you are what you eat”. This applies to everything on this planet that eats. Sourcing plant fertilizer is always a wise idea if at all possible because you want to know what they have been eating. This is another great reason to get to know your local farmers and ranchers.
You also want to be sure that you are not going to kill your plants with what you are feeding them. All types of manure need to compost otherwise it will burn the plants. The time frame can be anywhere from 3 months to over a year for chicken waste, the time frame varying depending on what animal type you use. After aging you want to add carbon-based materials to balance the nitrogen of the manure, such as leaves, straw or wood-based products. There is a lot of detail that goes into this process that I won’t visit now but you can find helpful resources here.
Skip the Fuss and Buy it
I have found one source of plant food on Amazon that is non-GMO called Organics Rx. They make four specialized types of fertilizer for vegetables, tomatoes, indoor plants, and rose and flower food. Find all of them at Amazon.com.
Azomite also makes a good fertilizer for many different applications. Consisting of powdered montmorillonite clay, it has a high concentration of nitrates and other trace minerals.
Life Force Seaweed Powder is a balanced fertilizer made of…you guessed it…ground up seaweed. Sea vegetables are high in micro-nutrients that plants need and can be used on indoor sprouts, indoor and outdoor plants, vegetables, trees and more.
You can find Azomite and Seaweed Powder at Wheatgrasskits.com.
