How to estimate ammendments from square feet

So im reading up on some of the ammendmenst I'm intersted in.

soil acififier
bone meal
fish meal
etc.

And many of the packages say to add so many pounds per so many suqare feet. I've got a few gallons of soil and I'd like to add the ammendments in TBS or CUP or gram quantities? WTF how do I estimate a volume dosage from a weight per area dosage.

If i figure the soil to be treated is about 12 inches then I can measure the surface area of my bag of soil at 12 inches deep and then cut the ammendments according to the surface area of the bag of soil at 12 inches deep.

But what if the ammendment assumes 6 inches deep or 10 inches deep.

Anyone thought about this before. I'm in need of help here, help. I don't want to put too much ammendment into my soil. Or too little for that matter.

Thanks for help. I'm desperately trying to get away from chemical ferts.

Well i figure if i get some square totes and fill them up with about 8 inches of soil then I'll just measure my amendments based on the surface area in the square tote. Anyone else want to chime in here...

Indoor grow im assuming? Did you buy your soil or dig it up? If you bought soil the bag says how many cubic feet are in it. You need to think of, and provide all the details with your initial post, so we have the appropriate amount of information to help you.

Ok wiseguy. I got a cubic foot of soil which is a volume measurement. My amendment instructions says to put 5lbs of shit for every 100 square feet which is a weight per area measurement. So how much you want to mix in my cubic foot of soil, bitch. I'm growing inside and I'm going organic. I've got like a shit load of amendments to add to the soil and most of the instructions say some shit like 1 tbs per plant or 2 lbs per 100 square feet. I got to figure out how much to put in a cubic foot of soil. It's not difficult. I can figure it out myself, ass hole. But I wanted to get some corroboration from the local community here. Anyone who's mixed their own soil has obviously run up against the same problem, fucko. Don't treat me like a fucking kindergartner, bitch.

All I want to know is how people choose their depth dimension to complete the cube when they are only given two dimensional dosages. So FUCK YOU Simply.

This site gets suckier every day.

I'd start with 1.5 cu ft = 11 gallons which was has been my slide rule for soil measurements.

The beauty about organics is that nothing is exact. You should explore subcool's super soil and mix a full recipe close to verbatim. If I were you, first fill the containers with soil to be planted and then follow the individual planting rates i.e. 1 tbs per plant etc. You don't need to make a single batch during this confusion.

Google LC's Soiless mixes or 3 Little Birds for ideas on different amendments/amounts.

Generally:
Bone meal-1cup/CuFt
Blood meal-1/2 cup/CuFt
kelp meal-1/2+cup/CuFt
Fish meal-??? 1/2-1cup? How hot is it?

Nothing is exact and all these recipe's are mostly just guidelines. You'll have to experiment on your own to get yours dialed in.

Just remember, it's a lot easier to add more, than to remove too much.

Now there's some good input! That's exactly what I did. Put it in a large plastic square tub. measured the depth of the soil to complete the cube and then used either the volume of the soil in the tub or the square area of the top of the soil surface in the tub to determine different doses. My base soil depth was 8 inches which is about what you'd need in topsoil to grow a plant in the garden.

My recipe was pretty much similar to Subcools with a few other hints and tricks from other helpful campers. The 30 day incubation period and the very good mixing is really what does the trick.
