Complete Organic Fertilizer


Complete Organic Fertilizer

To make enough COF to generously cover 100 square feet, mix:
  • 3 quarts oilseed meal such as soybean meal, cottonseed meal or canolaseed meal 
    or else:
  • 1 1⁄2 quarts feathermeal or fishmeal (smelly) or, the very best combination is probably:
  • 2 quarts oilseedmeal, 1 pint feathermeal and 1 pint fishmeal plus
  • 1 quart soft or colloidal rock phosphate (the best choice by far), or bonemeal
  • 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. Lime:
choose one of these two options:

If you garden where the land originally grew a forest, add these two:
  • 1 pint (0.473176473 l) agricultural limestone, 100# (fine grind) and
  • 1 pint agricultural gypsum; or else:
If you garden where the land originally grew prairie grass or is a desert add:

  • 1 quart (0.946352946 l) agricultural gypsum.

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

You may consider the following last four items 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.


1 quart = 0.946352946 l
1 pint = 0.473176473 l
1 feet = 0.3048 m
