I plant to mix up 3 large batches of the following soil mix:

1 Bail Sunshine Mix #4
8 cups Bone Meal
4 cups Blood Meal
1 1/3 Cups Epsom Salt
4 cups Dolomite Lime
4 cups Kelp Meal
30 lbs Worm Castings


This is basically Vic's Super Soil from the Overgrow FAQ. I already have enough epsom salt, and the worm castings is one bag per bail, but I need to know how much of the amendments I need to pickup from the store since money is an issue.

So in total I'm going to need:

24 Cups of Bone Meal
16 Cups Blood Meal
16 Cups Kelp Meal
16 Cups Lime

About how many pounds of each of the amendments should I purchase from the garden center?
