lime question for Burn One or Suby or other organic guru

[Imsostonedagain]

I just made a batch of LC's soilless mix #1. I was not able to find dolomite lime, but did find some called calcitic/dolomitic lime. It's contents are: CaCO3-75% , MgCO3-12%, Ca-30% , Mg - 3%. I imagine I will need more mag, if this isn't enough, can I just add epsom salt to my soil mix? Or to my teas?

Any help would be really appreciated?

 

[JackTheGrower]

I can't say much about the relationship but Dolomite is a slow lime that acts as a pH buffer?

I'd go with Crushed Oyster shell myself..

Anyone really know?

oops wrong post

 

[intotheunknown]

try this

try this

look around at your local nurseries or hydro shops for "sunleaves soil sweetener" which is 100% powdered dolomite lime. if they carry any of the sunleaves guanos they most likely have that as well.

 

[redneck shogun]

My local hydro shop even calls itself an organics store as well but yet they don't carry any kind of limestone or organic dry amendment for that matter. It's all Roots and AN products and 12 different brands of guano. If it isn't something they can sale at huge mark up then they won't carry it.

Lowes has powdered Dolomite. 40 lb sack for around $4.00

really, i did not know that. most places around here dont carry it, or its not powdered. and when you are at the end of your search and you just have to ask someone, you do and they look at you like youre retarded.

Virtually the same stuff. However the big box stores carry dolomite "soil sweetener" in fast powder and slow "prilled" form( little beads) very cheap.
But as was mentioned Oyster shell powder is in many ways better as it contains trace minerals from the sea and can be used just as one would dolomite.

Hey Imsostonedagain,

Dolomite lime is 50/50 CaCO3 and MgCO3 which makes it the best mineral source for both Ca and Mg. The CO3 ion will react with free H- ions to form H2O and CO2 so there is no residue. Everyone is happy, the plant gets the Ca and Mg and the soil is made less acidic.

With Epsom salts, MgSO4, there is an acidic salt residue of SO4- ions that will cause the soil pH to drop over time if continually added to the soil. Epsom salts work best when used as a foliar feed.

You can get away with putting in a bit extra of your Calcite as it is very slow acting.

I wouldn't use oyster shell as a substitute for dolomite. I would think that is bad advice. You can augment the dolomite with it oyster shells though, and gypsum too.

 

[microgram]

Most places I've been to only carry the granular form, EXCEPT bigger nurseries and hydro shops. Those two places are your best bets for this kind of stuff.

Been at this a long time and yes it can sub for dolomite. As either shell flour or crushed shell it works virtually the same as dolomite but has additional nutrients for the soil mycota.

I use oyster shell powder in conjunction with dolomite lime as well as gypsum. The specific product that I purchase is a product from Pacific Pearl down in Oxnard, California.

Here's the analysis posted at their web site:

Calcium Carbonate (CaCo3) Not Less Than 96%
Expressed as Calcium Not Less Than 36%

Calcium (Ca) 37.62%
Magnesium (Mg) .025%
Potassium (K) .05%
Sulphur (S) .037%
Phosphorus (P) .03%
Iron (Fe) .1176%
Manganese (Mn) .0370%
Zinc (Zn) .0033%
Copper (Cu) .0009%
Molybdenum (Mo) .0003%
Boron (B) .0021%

Good source of calcium carbonate and little else - again according to the processor's analysis.

YMMV

n' look at Me I'm a organic guru check the getup.

shh.. wait... dude shut up I'm gettin' somethin. Use my own shit instead of dolomite and you will be rid of all your ails.

here's the 40 lb bag of powdered dolomite at lowe's, in the lawn and garden section next to all the grass fertilizer products

Not sure where you are,but the bags we get up here in the PNW are from a brand called Greenacres

What you want is a 2 to 1 ratio of Ca to mg. What you have is calcitic lime. I use Algen Kalk as my source of calcium carbonate. It is seaweed derived calcium. I use it 1 TBS t 1 TBS dolomite lime.

You can use it but bring up the mg ratio without raising the ca ratio from the other lime.
