I'm often asked how much each one of our soil amendments weigh.
Here is a short post to help, rounded to nearest half ounce.
1lb = 16oz
1 Cup = 16 Tablespoons
1 Cubic Foot is equal to about 7.5 gallons of soil.
1/2 Cup Per Cubic Foot = about 1 Tablespoon per gallon.
Most amendments are recommended to be used with 1/2 Cup Per Cubic Foot of Soil and that Works out to about 1 Tablespoon Per Gallon of Soil.
Amendment Name: |

| Fish Bone Meal | 8 Ounces |
| Crustacean Meal | 7 Ounces |
| Kelp Meal | 7.5 Ounces |
