Growing pest free vegetables and fruits is in part dependent on not using chemical fertilizers and, instead, to rely upon the various natural resources available to us. It is not within the scope of this book to debate the difference(s) between organics and in-organics; nor is it my intent here to show why you should not use chemical fertilizers or if a plant can tell the difference between organic nitrogen sources and chemical sources1. I am not here to convince you that you should go organic and not chemical2.
These things you must have decided on your own. I am here to pass along to you my knowledge of Organics. In this chapter, I will cover some basic ways that you can make your own organic fertilizers. Please note that there are more and more organic fertilizers available on the market today, not all are 100% organic. Read the labels very carefully. The physical structure of what we feed the Earth can be modified. For example, a rock can be crushed into powder, or garlic made into a liquid. All these things are still subject to the laws of nature. They are Bio degradable and non-toxic.
The Invisible Gardener says: " High Nitrogen fertilizers can contribute to many insect & disease attacks if it not balanced with the proper minerals."
High nitrogen based fertilizers are like sugar to the human body. The rush is great going in, but not the going down! Each time you use high nitrogen, it causes greater stress then before. Beyond that you will find other causes that attract pests and diseases. High Nitrogen is like steroids for plants!
The Invisible Gardener says: "You can avoid many problems associated with high nitrogen use simply by understanding the organic system of providing nitrogen as the plant needs it"
