This is a thread for Natural organic fertilizers.

I have committed myself to growing only organic with anything from cannabis to strawberries. I have been doing research and searching around looking up all the natural fertilizers there are that nature itself provides for us. I have found a few but I'm hoping for more. :D

The Natural ferts I've found are: Cow Manure, Bat Guano, Compost, Worm Castings, Chicken excrements, Fish Emulsion, Seaweed, Volcanic Ash... and a few others that I may have forgotten. Anyways I created this as a little knowledge base for Organic Ferts. If you guys know any others that you would like to add then please post them. :) Hopefully this will help present and future growers alike.

List of Natural fertilizers/nutrients:
Cow Manure
Molasses
Bat Guano
Compost
Worm Castings
Poultry excrements
Fish Emulsion
Seaweed
Volcanic Ash
Bone Meal
Blood Meal
Alfalfa Meal
Kelp Meal
Seabird Guano
Hydrolyzed Fish
Shelfish Compost
Palm Bunch Ash
Human Hair
Soft-Rock Phosphate

P.S. If I have any incorrect information in the post, please post.

Thanks to Mother's Finest, Purple Rhinoceros, Matt Rize for providing info and input on the topic.

Off the top of my head, you're missing Bone, Blood, Alfalfa, Crab and Kelp Meals, as well as Seabird Guanos, Hydrolyzed Fish (similar to Emulsion), Shellfish Compost and a number of different ashes including high-Potassium Palm Bunch Ash.

There are many other organic substances that fall closer to growing mediums or Ph adjusters than actual fertilizers, even though most supply at least some micronutrients.

There are many more: SOFT ROCK PHOSPHATE being the crucial non-animal derived Phos source.
Yucca extract is worth mentioning.
So is molasses, vinasse, and sucanant.
Human urine is another good N source that is often overlooked.

Here is a rough guide

ALFALFA MEAL 3-0-2
contains fatty acid triaconatol, to to stimulate growth
Alfalfa meal or pellets are often used as animal feed. Primarily they are used to
increase organic matter in the soil but do offer nutrients and a high availability of
trace minerals. They contain trianconatol, a natural fatty-acid growth stimulant.
Alfalfa meal or pellets
Typical NPK analysis 2-1-2
Release time 1-4 months
Pros Available at feed stores
Cons May contain seeds​

Application Till in 2-5 pounds per 100 square feet


Corn gluten meal
Corn gluten meal materials have a high percentage of nitrogen. It carries a
warning to allow 1 to 4 months of decomposition in the soil prior to seeding.
Allelopathic properties will inhibit the germination of seeds. However, there is no
danger to established or transplanted plants. This product is also marketed as a
pre-emergent weed control for annual grasses in bluegrass lawns.
Typical NPK analysis 9-0-0
Release time 1-4 months
Pros Very high nitrogen
Cons Germination inhibitor, some are GMOs​

Application Till in 20-40 pounds per 1000 square feet

BAT GUANO 2-11-0
can be top dressedover soil, or disolved in water
Bat guano (feces) harvested from caves is powdered. It can be applied directly to
the soil or made into a tea and applied as a foliar spray or injected into an irrigation
system.
234-4
Bat guano – high N
Typical NPK analysis 10-3-1
Release time 4+ months
Pros Stimulates soil microbes
Cons Cost
Application Till in 5 pounds per 100 square feet or as a tea at​

3 teaspoons per gallon of water

Bat guano – high P
Typical NPK analysis 3-10-1
Release time 4+ months
Pros Stimulates soil microbes
Cons Cost
Application Till in 5 pounds per 100 square feet or as tea at 3
teaspoons per gallon of water​



BLOOD MEAL 14-0-0
fast and long acting supply of nitrogen (6months +)
Blood meal, made from dried slaughterhouse waste, is one of the highest nonsynthetic
sources of nitrogen. If over-applied it can burn plants with excessive
ammonia.
Typical NPK analysis 12-0-0
Release time 1–4 months
Pros Available at feed stores
Cons Can burn. Expensive at garden centers​

Application Till in 5–10 pounds per 100 square feet


BONE MEAL (steamed) 3-15-0
fast and long acting supply of phoshorous (5 months +)
A well-known source of phosphorus, bone meal is steam processed and widely
available at feed stores and in garden centers. If purchased at feed stores, P is
expressed on the label as elemental phosphorus and is 2.3 times higher than
numbers shown on garden center labels for phosphate (i.e. – 12% phosphate is the​

same as 27% phosphorus).
​
​
However, recent CSU research has shown that P
from bone meal is only available to plants in soils that have a pH below 7.0.
Typical NPK analysis 3-15-0​

Release time 1–4 months

Pros Highly plant available form of phosphorus
Cons Cost​
​
​

Application Till in 10 pounds per 100 square feet​



CANOLA MEAL 6-2.5-1
very affordable​

CHICKEN MANURE (composted) 2-7-2
numbers may vary; adds organic matter; makes good ferterlizer tea​

Colloidal phosphate – a.k.a. soft rock phosphate

This product is made by surrounding clay particles with natural phosphate. Total
phosphate is about 20% while available phosphate is about 2-3%. This is why you
can apply large amounts of colloidal phosphate, as it will release slowly over the
years (usually more available the second year than the first). For home gardeners
the cost/return is adequate to apply colloidal phosphate at rates to supply​

phosphorus for this season’s crops. This product also adds micronutrients to soil.​


COMPOST 1-1-1
adds organic matter and is good use of household waste​

COTTONSEED MEAL 7-3-2
good addmendment for a soil with worm activity
Cottonseed meal is a rich source of nitrogen. Buyers should be aware that many​

pesticides are applied to cotton crops and residues tend to remain in the seeds.
Pesticide-free cottonseed meal is available.​
​
​

Typical NPK analysis 6-0.4-1.5​

Release time 1-4 months
Pros High nitrogen
Cons Pesticide residues, most are GMOs​
​
​

Application Till in 10 pounds per 100 square feet​



EARTHWORM CASTINGS 5-1-1
acidic; improves soil structure, makes good ferterlizer tea​

EPSOM SALT 0-0-0
water soluble source for magnesium and sulphur​

FEATHER MEAL 14-0-0
good nitrogen source
Sourced from poultry slaughter, feather meal has fairly high nitrogen levels but is

slow to release the N.
Typical NPK analysis N varies 7 – 12% on process​

Release time 4+ months
Pros Long term fertilizer
Cons Cost versus speed of N release​
​
​

Application Till in 2.5-5 pounds per 100 square feet​



FISH AND CRAB MEAL 8-5-1
trace elements​

fish-bone meal 5-22-1
lots of calcium​

FISH EMULSION OR POWDER 5to12-1to2-1to2
water soluble
Infamous for its foul smell, emulsions are soluble, liquid fertilizers that have been

heat and acid processed from fish waste.
​
​

Typical NPK analysis 5-2-2
Release time 1 – 4 months
Pros Adds needed micronutrients
Cons Some have foul smell​

Application Mix 6 tablespoons per gallon of water​



FLAXSEED MEAL 6-3-2
mix into soil​

GRANITE (crushed) 0-0-8
best with high potassium feldspar content​

GREEN SAND 0-1-8
releases potassium for several years​

HORN AND HOOF MEAL 14-1-0
strong source of nitrogen​

KELP MEAL 1-1-2
King of naturally occuring trace minerals
Kelp meal, a product of the ocean, is used primarily as a trace mineral source. It is

often combined with fish meal to add N-P-K value.
​
​

Typical NPK analysis negligible
Release time 4+ months
Pros Adds micronutrients
Cons Insignificant NPK value​

Application Till in 1 pound per 100 square feet​



LANGBEINITE 0-0-22
can be agitated and disolved for faster availability​

LIMESTONE 0-0-0
for calcium, and to neutralize ph of soil/mix​

MUSHROOM MANURE 1-1-1
adds organic matter and provides many nutrients​

ROCK PHOSPHATE 0-27-0
contains a good supply of calcium​

Soybean Meal 7-2-1

Used primarily as an animal feed product. Available bagged at many feed stores.
Soybean meal
Typical NPK analysis 7-2-1
Release time 1-4 months
Pros High nitrogen, available at feed stores
Cons Almost half of the conventionally grown soy is
GMO​

Application 8 pounds per 100 square feet​



STEER MANURE 1-1-1
near neutral ph, adds trace minerals and organic matter​

SUNFLOWER HULL ASH 0-0-44
one of the strongest fast acting sources of potash available​

WOOD ASHES 0-0-8
increases ph​

I plan on doing an experement on this next grow. I want to try different varietys of natural ferts on the same strain to see which yields most. I am thinking of doing one w/ guano, and need to figure out the regimine of the other plants im including in the experement. For instance I may do fish emulsion for N on another one (not sure what I am using for phos), and so on and so on, down the line. Anyone have any good, natural, recipies they can suggest for the whole grow cycle of one of these plants in the experement? I will do a grow journal when I start and we can see how it fares against other mixtures.
