Complete Organic Fertilizer (COF) by Steve Solomon Original Founder of Territorial Seeds

Below is the COF recipe included in Steve’s new book:Mix Your Own

To make enough complete organic fertilizer to generously cover 100 square feet, mix:

3 quarts oil seed meal such as soybean meal, cottonseed meal or canola seed meal or 1 1/2 quarts feather meal or fish meal (smelly)
or, the very best combination is probably 2 quarts oil seed meal, 1 pint feather meal and 1 pint fish meal

1 quart soft or colloidal rock phosphate (the best choice by far) or bone meal
1 quart kelp meal and/or 1 pint Azomite (for trace minerals) (And/or apply liquid kelp every 2 weeks as a foliar throughout the season.)

Add lime: choose one of these two options:
If you garden where the land originally grew a forest, add these two:
1 pint agricultural limestone, 100# (fine grind) and
1 pint agricultural gypsum;

or if you garden where the land originally grew prairie grass or is a desert add:
1 quart agricultural gypsum

If you do not live in Cascadia, add 1/3 cup potassium sulfate.

The following last four items are optional:
1 teaspoon laundry borax or a smaller quantity of Solubor (1/2 gm actual boron)
1 1/2 teaspoons zinc sulfate
2 teaspoons manganese sulfate
1 teaspoon copper sulfate

Mix all ingredients are very thoroughly before spreading.
