anybody ever done the math on this to see how much fert you lose vs the gain in lime. I know the fert normally has filler in it. I was told the 50lb bag of this will have about 30lbs of lime. just rying to figure out if its worth it at 16.50 a bag
google says that normally there will be about 60% filler in a bag of just trip 13

Never heard of lime being in a bag of fertilizer. Also never thought about what was used as the filler either. Only 22.5lbs of fertilizer in a 50lb bag of trip 13.

the pelletized lime in lieu of rock filler sounds like a genius idea to me. If it is 13-13-13, then you are getting the same amounts of N, P, and K, in each 50lb bag so they have to be substituting the filler with some sort of pelletized lime. It's actually 19.5 total lbs of fertilizer in 50lbs of 13-13-13 so whomever told you the breakdown of what was in the bag was 20/30 is correct. Win win to me.

I mean, if you are paying 2.00 more for 30lbs of lime it should be a no brainer. unless im missing something

Where are you seeing this product?

I don’t think it’s a direct fertilizer/lime correlation. There are other elemental parts of the N-P-K that has to be accounted for. I’d like to see the tag/label.

I think it was Biologic that used to sell a pHertilizer that had lime in it. Someone else may offer similar.

I’ve got a pic of the label, pm me your # and I’ll text it to you
Greenpoint in evergreen is making it.

It shows 13% of the NPK’s
9% sulfur
13 chlorine
My math brings that to roughly 30.5 of fert with 19.5 of lime??
Is that right?

Can you post the actual contents if it does in fact have lime in it

I don’t know how to post a pic. If anybody does send me a pm and I’ll text you the image

Derived from:
Ammonium
sulfate,
Diammonium phosphate, Muriate of potash,
Pelletized Lime.
50lb(22.68kgs)

That's a brilliant idea using lime as filler. Who manufactures it and where'd you get it?

Greenpoint ag out of evergreen.
I got it at universal seed in trussville. I would think any co-op should be able to get it though

I imagine it's more expensive than regular fertilizer?

2.00 more than trip 13 regular

I don’t think the entire 39 lbs/100 lbs of filler is lime. Wish they would state it on the label

just spoke with a lady at Greenpoint and they only put 240lbs of lime into a ton of the fert when mixing. With 40 bags in a ton that only comes out to 6lbs of lime in a bag. Far from the 30lbs I was told was in it or the 20lbs I figured was in it.

so,, you are actually paying more per lb than you would for just pellet lime by itself. fyi

Thanks for the info buzzard!

This is correct. You can't add 13+13+13 together to come up with the weight of product of whats in the bag or Per 100lbs . Yes, that is the total NPK nutrients, but the forms of fertilizer used are do not have 100% active ingredients and can't be made that way. Example Potash is a mined rock that is a 0-0-60. There are multiple ways to make a 13-13-13 but with this one using the Ammonium sulfate it takes up a lot of weight and doesn't leave a lot of room for filler or pell lime in the case. I would choose this grade 13-13-13 over one made with urea and not Ammonium Sulfate. The sulfur from the ammonium sulfate in this grade will help your grass a lot.

Great breakdown Rosco!
