Remineralization worksheet download, part 2

So now that you know exactly how much of each individual element you need to remineralize your particular square footage, it should be easy, right?


Coming up with the proper ratios of elements in natural form is just mind boggling, a labrynthine math problem that used to take me weeks to figure out. It’s not that the math is really that hard; it’s more that every single item you change has repercussions in several different ways. You need to have the balance of all the elements in mind at all times.

Take kelp, for example. 1% N, 0.3% P, 2% K, 2% S, 2% Ca, 0.7% Mg, 0.12% Mn, 0.1% Fe, and on and on. So say you used enough kelp to meet your potassium requirements  – well and good, but then you also have a Calcium requirement that isn’t yet met. So you add a bunch of gypsum… but now your sulfur is through the roof and you’re going to burn all your plants. Now realize that there are 16 elements on this sheet to keep track of at the same time. See how it can get complicated?

Enter The Spreadsheet. Glory in the Excel.


First, I listed all the fairly easy-to-find organic fertilizers and their respective percentages of each mineral they contain. (The pic above is just a small example). I also included organic fertilizer blends from Espoma that are widely available nation-wide.

If you then put a theoretical number (pounds) in the left hand column, and have the percentages of each mineral helpfully multiply themselves by that number and add themselves up in a row up top, it becomes incredibly easy to jockey around with the numbers and add a little here, take away .2 pounds there, try adding some of this other thing instead… until you have the perfect ratio in a sort of shopping list down the left hand side.

Sometimes you can get very, very close. Compare the numbers needed (in yellow) to the pounds that’d be supplied by my theoretical shopping list (just under the yellow).

Then download by following one of these two steps:

1) download the sheet in microsoft excel format to your own personal computer. There, you can edit it as you like and save it as a different document.

2) open the shared document. Go to File -> make a copy . You’ll be asked to rename your own copy and that one ought to be editable. It should automatically save to your Google Drive account.

I wish I’d done this years ago! I sure hope it can help lots of people increase the fertility of their soil – please drop me a comment below to let me know what you think! I’d love to hear if it’s working for you. :)

    i came across your information on soil analysis and read
    “the intelligent gardener” . It’s super complicated for me especially the math. I saw your awesome excel sheet but my question is PPMs. I don’t know how to convert all the results into ppms. Some of the results i.e. K is lb/ac. what do i do with that?

    Hello! Sorry I’m just getting back into blogging after a long hiatus. I’m not sure what PPMS is? But you’ve probably had your question answered long since. :) How did it go?
