Easy Organic Soil Mix for Beginners

I by NO MEANS claim this as my own.
I found this doing research since I am starting up a organic grow.
I have done a lot of research and have found a lot of it confusing and /or so labor intensive.
Not EVERY ONE has a place to put bags of soil, and multitudes of amendments or be able to BREW tea.
Since I am a LUCAS FORMULA fan, and LOVE the K.I.S.S. system, I wanted something less complicated a SMALL gardener can do (or a med patient??) easily.
I think this is it…. A K.I.S.S. way to easy organics…
This is NOT for all you ORGANIC GURUS out there. This is just a easy simple way for a average person to get up and going using organics living soils. While I am sure some will say “add some of this or that” The WHOLE prmise is to Keep It Simple Stoner!!!
My thanks to “In the garden” and “Ganja Girl”….

So you want to go organic but don't know where to start? Here's a recipe for an easy, organic, water-only soil that will provide more than enough nutrition for your plants. It's also a cheaper way to go organic. This soil can be reused again and again, so in the future you can add "extra" amendments if you like, or as your budget allows. The first part of this thread will detail a super easy, basic organic soil mix. This soil mix will grow gorgeous, healthy plants and is easy to make-you don't have to source a million different amendments. This simple soil mix contains all the nutrition that your plants need. All you have to do is water with dechlorinated water.
The next part of the thread will talk about "extra" amendments that you can add, now or for future grows. These amendments are very beneficial and will absolutely improve your soil, but they aren't necessary and you don't have to have them to get started. Please note that all pictures are shown only as a guide, you do not have to buy these specific brands. Get what is available in your area.

Just a note: the best place to buy organic gardening amendments is from a feed/farm store. Hit up google and try to find one in your area. The feed store will have the best selection and prices, and will make the process much easier.

Here's what you need to get started:

Base Soil:
Canadian Sphagnum Peat Moss

Aeration amendment (to help with drainage and allow oxygen into the soil). Some common aeration amendments are: perlite, pumice, turface, rice hulls, calcined diatomaceous earth (Napa Auto parts product # ). You only need to pick one of these, and you should choose whatever's cheapest and most easily sourced. If using perlite, make sure that your perlite does not have slow release chemical fertilizers added (Miracle gro perlite has chemical fertilizer added and should be avoided)

Humus (compost/earth worm castings (ewc) ). High quality humus is the key ingredient in an organic soil. Without good humus you've just got a bucket of peat moss and some amendments. You don't have to add both compost and ewc, just one will do, but if you have access to both, the more diversity the better. The bagged manure compost from the store really won't do. Look on craigslist for a local source for compost or ewc. There are some good bagged composts like Coast of Maine bagged composts, Bu's Blend Organic Biodynamic compost, and Farmer D's Organic Biodynamic compost. EWC can be bought on ebay. If your budget won't allow you to buy enough high quality humus (or if you'd have to order it all), buy as much good ewc as you can. Then buy the best bagged compost available in your area. If you want, you can make an ACT with a small amount of the ewc and use it to inoculate the bagged compost. This will increase the viability of the bagged compost.

Nutritional Amendments:
Dry Organic Fertilizer. My favorite is Espoma "tomato tone". Espoma "garden tone" and "plant tone" are also excellent choices. More good choices are Dr. Earth "all purpose" or "tomato and vegetable blend" and Down to Earth "all purpose blend". Use what you have available.
Kelp meal. Kelp meal is a good source of K, but its real value lies in its micronutrient content. Kelp meal contains all the micronutrients your plants need, and it's also full of growth-stimulating plant compounds.

Mineral Amendments:
Lime. Used to neutralize the acidity of the peat moss and help stabilize pH. Look for agricultural lime, garden lime, or dolomite lime. Avoid "fast acting" or "hydrated" lime-these have been treated with chemicals that you do not want in your garden.
Rock Dust. Rock dust helps to mineralize the soil but it's real value is as a "home" for the microbes and an anchor for the fungal hyphae in our soil (see jerry's excellent "rock dust" thread for more info). Dust from igneous rocks like granite, basalt, azomite, glacial rock dust, etc. is what you want. Granite dust can be found very cheaply at a local stone cutting place or at a place that sells mulch/topsoil/gravel/stones. Granite dust is an excellent rock dust and this is the cheapest option.

Now for the soil mix. First you want to make a base mix comprised of peat moss, humus (compost and/or ewc), your aeration amendment of choice, and lime. The soil mix should be about 1/3 peat moss, 1/3 humus, and 1/3 aeration amendment (don't stress out if you add a little too much of one thing or your ratios aren't exact, it will be okay). If you want to use a 50/25/25 ratio of peat moss/perlite/humus, that's fine too. You can use a 5 gallon bucket (or a 1 gallon bucket) to measure. Remember when making your soil that 1 cubic foot = 7.5 gallons. You can use just the plain base soil for starting your seeds and clones.

Note: we are using a 5 gallon bucket to measure, so 1 part=1 full 5 gallon bucket, 1/2 part=1/2 of a 5 gallon bucket, or 2.5 gallons

To make 1 cubic foot (7.5 gallons) of base soil:

1/2 part peat moss
1/2 part humus (compost and/or ewc- can do all compost or all ewc or some mixture of the two)
1/2 part aeration amendment
1 cup lime (per cubic foot)

Nutritional amendments: you want to add about 2-3 cups total of all your nutritional amendments per cubic foot (7.5 gallons) of soil. Note that this means 2-3 cups total, a combination of all your nutritional amendments, not 2-3 cups of each amendment.
1 cup kelp meal
1.5 cups dry organic fertilizer

Mineral amendment: now add 4 cups of your rock dust per cubic foot (7.5 gallons) of soil

Mix all the above ingredients well. Now moisten the soil by adding water and mixing until the soil is about as damp as a well-wrung out sponge. Now let the soil sit for 3-4 weeks to allow the microbes to begin to break down the amendments and convert the nutrients into a form that the plant can use. This process of nutrient cycling is also referred to as "cooking". Neither heat nor the sun are required, the soil can "cook" inside just fine. You can go ahead and fill up the pots you plan to use and let the soil "cook" in the pots. You can moisten the soil with an ACT if desired to help jump-start the nutrient cycling process.


Additional amendments:

There are many additional amendments that can be of benefit in an organic soil. Here I will talk about several and discuss what benefits they add to the soil. The above soil mix with dry organic fertilizer and kelp meal will provide for all your plants nutritional needs, you do not have to add any of these amendments. You can add 1 of these "extra" amendments to your soil, or all of them, or none at all. Or you can start with just tomato tone and kelp meal, then add "extra" amendments to your soil in the future as your understanding of organic gardening improves (or as your budget will allow).

The rate of application for nutritional amendments is 2-3 cups total of nutritional amendments per cubic foot of soil. Note that this is 2-3 cups of all your nutritional amendments combined, not 2-3 cups of each amendment. Obviously if you are using additional amendments, you would disregard the amounts of dry organic fertilizer and kelp meal given in the previous post and instead just include those in your amendment mix.


Neem meal: Neem meal is a good source of N and many other macro and micronutrients and beneficial plant compounds. It is a nitrification inhibitor, meaning that it prevents the loss of nitrogen as nitrogen gas (specifically, neem prevents soil microbes from converting nitrogen compounds into nitrogen gas), thus keeping nitrogen in the soil. Neem also has tremendous value as a pesticide. Including neem meal in your soil mix will help greatly in preventing pest problems.

Alfalfa meal: Alfalfa is an excellent source of macronutrients (N,P,K), plus many vitamins and micronutrients, most notably Ca. Alfalfa also contains 16 amino acids and beneficial plant compounds like triacontanol, a compound that stimulates growth and branching.

Crab meal: Crab meal is a good source of N and P, and is an excellent source of Ca. Crab meal also contains chitin, which acts as a pesticide. The chitin in crab meal stimulates soil microbes to exude an enzyme called chitinase. Chitinase breaks down the exoskeletons of many pests and their eggs (the exoskeletons and eggs contain chitin, and the chitinase breaks down this chitin).


How to use additional nutritional amendments:
If you are using multiple nutritional amendments, it's easiest to make a blend of equal parts of all your nutritional amendments (except kelp meal, use double the amount of kelp meal), then add this amendment mix to the base soil. Apply 2-3 cups of the amendment mix per cubic foot (7.5 gallons) of soil.

For example, if you want to use kelp meal, a dry organic fertilizer (like tomato tone), neem meal, alfalfa meal, and crab meal as amendments, here's what you do: (I am going to say 1 cup=1 part for illustrative purposes. If you need more or less, just have 1 part equal to more or less than one cup.) (any leftover amendment mix can be stored in a ziploc or tupperware container)

-Amendment mix: 1 cup dry organic fertilizer, 1 cup neem meal, 1 cup alfalfa meal, 1 cup crab meal, 2 cups kelp meal.
-Now add 2-3 cups of this amendment mix per cubic foot of soil. Store the rest for later use in making more soil or as a top-dressing.







Re-using Your Organic Soil

Organic soil can be re-used over and over again. In fact, the soil actually gets better as it ages! Organic amendments take a long time to break down-definitely longer than a single grow cycle and years in some cases. You can even re-use the soil without adding any extra amendments. A plant only uses a small amount of the nutrition available in an organic soil, so remember that there's still a lot of good stuff in there. Soil can be used for several grow cycles without any additional amendments-you can grow for years without re-amending it. Also, if your garden is no-till, then you wouldn't follow this re-amending procedure. Just top-dress with some extra "goodies" every so often.

It's important to note that re-amending your organic soil is an art, not a science. While the recommendations I've made below are good, your soil may need something a little different. If your plant showed any kind of deficiencies, you'll need to amend the soil to correct for those now. Ultimately you should trust your gut and go with what you think is best over following a prescribed formula. The only thing you should absolutely add more of is your humus, and then any extra aeration amendment needed to offset the additional humus.

I like to lightly re-amend after each grow cycle or two to keep a steady supply of amendments in multiple stages of decomposition. After harvesting, pull out the root balls and soil and dump them in a large container. Use a shovel to chop up the roots as best you can (don't sweat over this). If you shake the soil off the root balls, then allow them to dry out for a day or two, they will break up pretty easily. Then add the root balls and old soil to some new soil or just use as-is if you don't have any new soil.

Add:
-additional humus (ewc and/or compost) at the rate of 1 part humus to 4 parts old soil.
-additional aeration amendment: add about half as much additional aeration amendment as you do additional humus (so if you add 4 gallons of compost/ewc, add 2 gallons of aeration amendment). You may need to add more to keep the level of aeration amendment consistent with that of the original soil-go with what you think is best.
-kelp meal: 1 cup per cubic foot of soil.
-dry organic fertilizer: about 1/4-1/2 cup per cubic foot.
-liming amendment: approximately 1/4 cup liming amendment per cubic foot of soil

If you amend soil this lightly, you don't have to let it sit and cycle (cook) before using it again-just toss a new plant right in. However, if you add any "extra" amendments or more than about 1/2 cup per cubic foot of the dry organic fertilizer, you will need to let it cook for 2-4 weeks before re-using it.

At this point you can also add any new "extra" amendments that you want to add. I would recommend adding about 1-1.5 cups total of additional amendments. Remember that if you add "extra" amendments you will need to allow the soil another 2-4 weeks of cycling (cooking) to give those amendments time to break down.
Let's say that you started with the base soil amended with only kelp meal and dry organic fertilizer, and now you want to several "extra" amendments (or just one, whatever you like). Make a blend of all the amendments you want to add, using equal portions of all amendments with a double portion of kelp meal. Now add 1-1.5 cups of this mix to your organic soil and allow to cycle for 2-4 weeks, or more (the longer the better).

Again Much Thanks and Love to GanjaGirl, & Inthegarden.

That is a lot to read for a KISS explanation but I like where you're going with it all.

I believe coot said it the most simple:

The Cootz Mix:

Equal parts of Sphagnum peat moss, some aeration deal (pumice, rice hulls, lava rock - whatever is sitting in the garage) and finally some mix of humus - my compost, worm castings some black leaf mold I bought from the local 'worm guy'

To each 1 c.f. of this mix I add the following:

1/2 cup organic Neem meal
1/2 cup organic Kelp meal
1/2 cup Crab meal (or Crustacean meal when available - it has Shrimp meal with the Crab meal. It's a local product from the fisheries on the Oregon & Washington Coasts)

4 cups of some minerals - rock dust

After the plant is in the final container I top-dress with my worm castings at 2" or so and then I hit it with Aloe vera juice and Comfrey extract. Or Borage. Or Stinging Nettle. Or Horsetail ferns. Whatever is ready.

That's it.

To recycle I've just been letting the root ball breakdown and I remove it. I dump the potting soil into an extra large SmartPot container (50 gallons) and add some new potting soil mix as above. I water it down with Kelp meal and Comfrey tea and let it sit until I need it.

Ain't rocket science......

The 'rock dust' term I used should have included an explanation, i.e. it's a mix I had made and bagged:

4x - Glacial Rock Dust - Canadian Glacial (Gaia Green label)
1x - Bentonite - from the pottery supply store in PDX
1x - Oyster Shell Powder - the standard product from San Francisco Bay
1x - Basalt - from Redmond, Oregon (new product at Concentrates - about $18.00)

No Dolomite Lime, Greensand or SRP was used. Or Azomite.
 
That mix looks to me like it'll grow healthy plants. Props for posting it up, and props for giving credit where credit is due.

Looks like a good mix for people just getting started with organics.

I'm interested in making a ROLS using coco as the base instead of peat. Coco lends itself to re-use. Any suggestions on needed alterations to the amendments? I may use gypsum, more for the sulphate than Ca, but no lime since my tap is very high lime. Thanks. -granger

Why Coco? I'd like to know why you think it would be better, and I'll do what I can to help. Just don't say... cause I have it already haha.

Why re-invent the wheel.

If you are trying to be sustainable then use Leaf mold or just compost.

Here is a cool paper I like:

http://cpl.usu.edu/files/publications/factsheet/pub__9468201.pdf

Peat recycles excellent! Eventually you will have a soil made from the top down from constant topdressing and mulching. Your aeration will come from worm holes and roots that grow into the soil. NO till is awesome!!! I never recycle anymore, just topdress and then mulch.

Don't mind the funky look, she is coming back into veg after being cloned from a plant deep into flowering.... just see the mulch.... that is SOOOO important in organics. Just mulch somehow someway. I like clover cause it's a nitrogen fixer and some barley straw.... but I change it up by topdressing special plants I grow too, like nettle, mint etc.

Not because I have it. I like coco, and I'd like to see how it does. So do you topdress/mulch in 5 gal containers? You don't remove the soil after a crop? You just plant and topdress? I've been growing in coco in 3 gal. Would I need to step up to 5's for ROLS? Thanks. -granger

I know it READS hard. Thats cuz i copied and pasted it to this forum.
The original reads a LOT easier
For TONS more info on this method and to find the original posting:
Do a yahoo search for:
"Easy Organic Soil Mix for Beginners"
its in Grasscity forum

I tried to add a link to this info but i couldnot.
Maybe someone else may be able to
Peace

I just mixed up a mix of spachum moss, earth worm poop, Mushroom compost, espoma tomatoe, alfalha, kelp meal. Rock dust and lime.
Everything i could not source out local i got off ebay in small manageable amounts
(alfalpha, kelp, rock dust, dolimite lime.)

I've seen the nearly 10 year old Utah study before. Does not apply.
50% perlite
Fe is only trace min
No Mg [so of course they were chlorotic]

This is highly contrary to the kind of yield, etc. experienced by 10's of thousands of people, including me, growing Cannabis in coco. -granger

Then don't ask!

My opinion on the subject is that coco users want so bad for it to be magical.... and then say it's better for the environment.

Personally I just go with what works best and is most affordable.

The environment thing is debateable and why I'm moving towards leafmold and the complete removal of peat in my mixes.

Try peat and also try coco side by side.

With coco, you are paying more and also worrying more.

But at the end of the day, if the coco works better than DO IT! and show us that too...

But don't force it to work just because it is coco and is cool.

If you like coco, just to like it.... do a comparison with PeatMoss and one with coco, I think you will be surprised. Coco has it's place... and seeing people grow trees out of a gallon of coco is awesome.

Topdress/mulch in 5 gallons?

I mulch in 1/2 gallons sometimes when I have clones or seedlings going, so yeah, mulching is easy and then you don't get dry soil on top.

I don't use 5 gallon buckets but many many people do and are able to go no till for several runs before dumping the soil for a full recycle. I've seen some phenomenal results from 5 gallon buckets as long as they are put into flower before they are too big. I personally use 30 gallon bags so i don't ever have to recycle, but I have no tilled 5 and 10 gallons before no problem.

Clover is cheap and you just sprinkle the seeds on top of your bucket with the plant in it and then keep the top moist for a couple days while they sprout. Then as the clover grows taller just cut it with scissors and drop in on top. This will feed the microlife and the soil... the worms etc. Read up on the mulching thread because there are a million ways to mulch and they all work to some degree.

How much space do you have? If you have space for 5 or 7 or even 10 gallon containers that would be awesome! To me the larger container allows me to have a low stress grow that I don't have to dode over.... but the mulch will help either way.

When I harvest, I cut the stalk off and take the plant away.

Now I have a container of soil with a stump sticking out.

I usually will grab that with a twist and pull and that pulls out just enough for me to plant my next clone or seedling into.... I usually need a decent size whole because I often transplant from a 1 gallon if they are seedlings that needed to be sexed.

If the plant I harvested was doing really really well, than I will probably just plant and go with no topdress, the mulch will still be there from the previous run and I just move it aside to plant.

On the other hand, sometimes I will harvest a plant and then take the mulch off the top.... scatter some neem cake and kelp meal, cover it up with worm castings an inch thick and then sprinkle clover all seeds all over it with a very light layer of mulch down on top so the seeds still grow.

Once the clover sprouts and starts growing... .and when i need that container of soil again (usually within 2 weeks) I'll grab it and plant right into it and start the cycle over again. All the while taking time to make sure the moisture stays nice and the bag of soil without a plant is just as happy as the others.

I really enjoy topdressing with lots of worms from the worm bin too, but I don't always have tons of extra....

MHG,
Thanks for the cultural info. But whadaya mean, don't ask? I didn't ask you specifically. Are you trying to stifle experimentation? And no, I'm not in love with coco just because. I want to see if it works for ROLS, and how well. I could ask you the same questions about peat. Someone will have to try a coco based ROLS to find out if it performs better or worse than peat based ROLS. I think that's worth knowing. When I get around to it, I'll report back. Good luck. -granger

Hey MHG
Thanks for your input.
The imix you use is real close to what i found. They say one can add in neem and crab too, but since its my first run i will go without this time, and add that the next run to "compare"
Appriciate all your info...thanks!!!
 
Granger - I see no reason a coco-based mix couldn't be reused repeatedly just like a peat-based mix. Different strokes for different folks. Peat and coco have slightly different properties, but when you add a pile of compost and quality amendments I predict you will see similar results.

My current mix is peat-based, but I definitely see the appeal of coco...

Give it a try!

Thanks, Spicy,
I plan to give it a try, but it'll probably be awhile because of my situation, and because I want to do a lot of research on ingredients, proportions, etc. I'd like to incorporate neem cake, crab meal, fish bone meal, and maybe Nutritional Yeast Flakes. No blood meal for me. Swore off that nasty shit years ago after a couple of guerrilla crops before you could get predator urine crystals to keep the deer and rabbits away. Don't want to smell it, breath it, etc., and I have to do my mixing indoors. Don't want blood runoff. Of course, maybe the cooking time will fix that angle. How much cook time is best without waiting forever? Not for the blood, since I won't use it, but for everything else.

What I really need to find out about is how quickly some of these things are released. Por ejemplo, fish bone meal. And I want the N to be available early, but not late. Blood meal is good in that way, but as I said... And like you said-different strokes... Good luck. -granger
