Organic PH adjusting

Minerals

Greensand N= 0 P= 1.5 K= 7
comments- Mined from old ocean deposits; used as soil conditioner; it holds water and is high in iron, magnesium, and silica - 32 trace minerals in all.

Eggshells N= 1.2 P= 0.4 K= 0.1
comments- Contais calcium plus trace minerals. Dry first, then grind to powder.

Limestone (dolomitic) N= 0 P= 0 K= 0
comments- Raises pH, 51% calcium and 40% magnesium.

Limestone (calcitic) N= 0 P= 0 K= 0
comments- Raises pH, 65-80% calcium, 3-15% magnesium.

Crustacean Shells N= 4.6 P= 3.52 K= 0
comments- Contain large amounts of lime. Should be ground as finely as possible for best results.

Organic Fertilizers - Composition

Organic soil composition involves creating a soil medium that has a balanced amount of nutrients - NPK as well as trace elements and minerals - plus organic material that provides food for not only the plant, but also the countless soil microorganisms, fungi, worms, and bacteria that comprise a healthy soil. This soil life breaks down the raw materials of the fertilizers you add so the plants can absorb them, and also plays a part in as-yet undefined processes that aid plant growth and improve soil health.

Below are various "recipes" for both organic fertilizers and organic soil mixes.

Mix and match formulas

Pick one source from each category. The results will vary in composition from 1-2-1 to 4-6-3, but any mixture will provide a balanced supply of nutrients that will be steadily available to plants and encourage soil microorganisms.

Nitrogen

* 2 parts blood meal
* 3 parts fish meal

Phosporous

* 3 parts bone meal
* 6 parts rock phosphate or colloidal phosphate

Potassium

* 1 part kelp meal
* 6 parts greensand :thumbsup:

exelent chart ,thanks

Accually at the bottom it tells you what to use for organic N-P and K.

epsom salts not organic.also let tap water sit out for 24 hrs,to get rid of chlorine,that will kill a organc grow.use dolimite lime and then u shold not hav to supoosely worrie about ph.

Good advise Butthead.
Exept for the Epsom salt part...I'm pretty sure salt is a naturally organic thing.SALT? :confused:

verdicts in had it checked out,just wat i thought about the epsom salts u buy in stores http://www.overgrow.com/edge/showthread.php?t=738829

So what is the conclusion ,some is and some isn't?
Obviously if you are growing organiclly you would use the salt straight from the earth.Not some proccessed shit.
But good lookin out...thanks.
Plus I'd only use it if I needed some Mag in my diet(by me I mean my plants)
