Organic Silica

What sources, other than greensand are organic for silica? A silica foliasr, I assume is not an organic source?

Thanks guys

Stinging nettles along with some other plants... I THINK horsetail and russian comfrey have it also. Some of the others like JayK will know for a fact.

I also use Dyna Gro Pro-TekT and is my most used bought product. Especially if you live in a place with high heat or powdery mildew problems. It tends to make my branches/mainstem much thicker.

Azomite and Diatomaceous Earth are VERY good organic sources of silica...

Or if looking for shelf line fertilizers, something like Gen Hydro "Rare Earth"...

We use pumice sand in our mixes here. Silica become available from this?

According to my textbook silica aids plant strength and immunity. Good stuff.

As for the Rare Earth stuff just look for pyrophyllite clay like that from www.vitalityherbsandclay.com instead of Rare Earth for starters and yeah Azomite is similar.

Horsetail is an awesome plant source of silica.

I thought it's rice hulls that contain a lot of silica and not the rice itself?

rice has some, but the hulls have a lot more. rice hulls are cheap as hell too ( 6CF for 5$ here). nice substitute for perlite.

I've also heard it's important to use composted rice hulls instead of the green stuff? Supposedly in a very active, microbial enviro, the hulls only hold up for about 3 cycles then are gone...unlike perlite.

they become micro aggregates (rice hulls) and continue to build soil structure, nothing wrong with that considering ther price and benefits

actually the hulls i get at the feed store for my chickens ( same stuff used in soil ) are parboiled and dried. not fresh and green, never even seen the green kind before. when i use it in the veggie starts in the spring to sell, it works great 60/40 compost/rice hulls. and to that 10% char.

the hulls i have found in the actual soil/ground only last a season for me. and when composted with the chicken manure its gone in a few weeks. i dont really need anymore in my soil, but for soil that's not so great, it would be a good amendment along with some compost. get the soil kickstarted fast.

but thats ok that it breaks down, its just more organic matter for the soil and eventually more humus formation. i think its great stuff if you can get it, specially as cheap as it is here. the price of perlite is crazy, plus is sucks im comparison imo.

one other thing its really good for is making biochar, the stuff is already really small so you dont need to smash it up at the end which = no massive dust clouds. this is probably my main use for it along with animal bedding.

sorry if that was off topic :X

One time I was looking at getting a truckload, I mean like a semi, direct from the mills and did some research into the stuff. I don't think you'll find any green stuff in the general market but if you're dealing 'direct' you will probably come across some.

Well I agree...what about GH rare earth?? Never tried it.
Rare Earth is just an expensive way to get pyrophyllite clay mixed with some humic stuff. The clay however is loaded with silica, especially amorphic and not crystalline, and for organic soil you can skip the extra humic. I talked to the clay supplier and a cool thing is you need to replenish it in soil soil every now and then as it breaks down and gets used up by the 'system'. He was recommending the granular form for general gardening.
