How much does each amendment weigh? January 10 2014, 11 Comments

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:

Weight In Ounces Per Cup:

Fish Bone Meal   8 Ounces 
Crustacean Meal 7 Ounces
Kelp Meal 7.5 Ounces
Neem Cake 6.5 Ounces
Alfalfa Meal 2 Ounces
Oyster Flour 8 Ounces
Gypsum 9 Ounces
Soft Rock Phosphate 9 Ounces

Glacial Rock Dust

9 Ounces

Barley Seed

6 Ounces
