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)
