Organic Nutrient Chart

Use this handy chart to pick which fertilizers and nutrients you’ll be using in your
grow operation.

Manures
source N P K comments

Rabbit manure 2.4 1.4 0.6 Most concentrated of animal manures in fresh form.

Cow manure (dairy) 0.6 0.2 0.5 Often contains weed seeds, should be hot composted.

Steer manure 0.7 0.3 0.4 Often contains weed seeds, should be hot composted if fresh.

Chicken manure 1.1 0.8 0.5 Fast acting, breaks down quickest of all manures.
Use carefully, may burn. Also, stinks like hell - composting definitely recommended.

Horse manure 0.7 0.3 0.6 Medium breakdown time.

Duck manure 0.6 1.4 0.5 .

Sheep manure 0.7 0.3 0.9 .

Worm castings 0.5 0.5 0.3 50% organic material plus 11 trace minerals. Great for seedlings, will not burn.
Is a form of compost, so doesn’t need composting.
Desert Bat Guano 8 4 1 Also contains trace elements. Fast-acting, mix in soil or as tea (1 C guano to 5 gal. water).

Cave Bat Guano 3 10 1 .

Fossilized Seabird Guano 1 10 1 Slow release over 3 to 12 weeks, best used as an addition to potting mix.
Peruvian Seabird Guano (pelletized) 12 12 2.5 Legendary fertilizer of the Incas. Use in soil as a long lasting fertilizer, or make into tea (1 tsp pellets to 1 gallon water).
Note: it is recommended to first compost any fresh manure before you use it for 2 reasons:
1) to lessen the chance of harmful pathogens.
2) to break down the manure to make it more usable to the plant (and reduce the smell!)
The rates for pig or human manure are not listed because of the high rate of harmful pathogens they contain.

Organic meals
source N P K comments

Blood Meal 11 0 0 Highest N of all organic sources, very fast acting if made into tea.

Bone Meal (steamed) 1 11 0 Releases nutrients slowly.
Caution: European farmers should not use because of the risk of spreading Mad Cow Disease; growers elsewhere may face the same issue.

Cottonseed Meal 6 2.5 1.5 If farming organically, check the source. May be heavily treated with pesticides.

Fish Scrap 5 3 3 Use in compost or work in soil several months before using. Usually slightly alkaline.

Fish Emulsion 4 1 1 Also adds 5% sulfur. Good N source for seedlings, won’t burn.

Kelp Meal 1 0.5 2.5 Provides 60 trace elements, plus growth-promoting hormones and enzymes.

Soybean Meal 7 0.5 2.3 .

Coffee Grounds 2 0.3 0.2 Highly acidic, best for use in alkaline soils.

Minerals
source N P K comments

Soil amendments and organic material
source N P K comments

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

Herbal Tea Plant Food

1 t Comfrey leaves
1 t Alfalfa leaves
1 t Nettle leaves
1 Qt boiling water

Steep for 10 min. and let cool until luke warm. Drain the leaves out and add the luke warm tea to your plants to keep them healthy and vibrant!

The reason for adding slightly warm tea (or water) to your plants is that they will be able to absorb the needed nutrients more easily by keeping the root pores open verses cold tea (or water) will have a tendency to restrict the pores, meaning a much slower process of absorption.

Comfrey is called knitbone or healing herb. It is high in calcium, potassium and phosphorus, and also rich in vitamins A and C. The nutrients present in comfrey actually assist in the healing process since it contains allantoin.

Alfalfa is one of the most powerful nitrogen - fixers of all the legumes. It is strong in iron and is a good source of phosphorus, potassium, magnesium and trace minerals.

Nettles are helpful to stimulate fermentation in compost or manure piles and this helps to break down other organic materials in your planting soil. The plant is said to contail carbonic acid and ammonia which may be the fermentation factor. Nettles are rich in iron and have as much protein as cottonseed meal.

Short Guide to Organic Fertilizers for Medicinal Marijuana

We’re slowly working on a more complete medical marijuana growing guide that will include an entire series of essays and entries similar to our previous Guano Guide / Manure Manual as well as our Molasses Manual. As that work progresses, we’ll be including bits and pieces of our research,

Table 1. A Selection of Organic Fertilizers for Use in Growing Mediaa
Fertilizer Material

Estimated N P K Rate of Nutrient Release Salt & pH Effects

Alfalfa Meal 2.5 0.5 2.0 Slow

Blood Meal 12.5 1.5 0.6 Medium-Fast

Bone Meal 4.0 21.0 0.2 Slow

Cottonseed Meal 7.0 2.5 1.5 Slow-Medium Tends to acidify

Crab Meal 10.0 0.3 0.1 Slow

Feather Meal 15.0 0.0 0.0 Slow

Fish Meal 10.0 5.0 0.0 Medium

Granite Meal 0.0 0.0 4.5 Very Slow

Greensand 0.0 1.5 5.0 Very Slow

Bat Guano 5.5 8.6 1.5 Medium

Seabird Guano 12.3 11.0 2.5 Medium

Kelp Meal 1.0 0.5 8.0 Slow Possibly high-salt

Dried Manure Depends on Source Medium Possibly high-salt

Colloidal Phosphate 0.0 16.0 0.0 Slow-Medium

Rock Phosphate 0.0 18.0 0.0 Very Slow-Slowc

Soybean Meal 6.5 1.5 2.4 Slow-Medium

Wood Ash 0.0 1.5 5.0 Fast Very alkaline, salts

Worm Castings 1.5 2.5 1.3 Medium

(a) Information in the table has been adapted primarily from Penhallegon, Ross. 1992. Organic fertilizer NPK values compiled. In Good Tilth. January. p. 6.; and Rodale Staff. 1973. Organic Fertilizers: Which Ones and How To Use Them. Rodale Press, Emmaus, PA. p. 50.

(b) Cottonseed meal from many sources may be too contaminated by routine pesticide use to be permitted in certified production. Growers should consult their certifiers before using.

(c) The availability of phosphorus in different forms of rock phosphate depends on the pH of the mix, biological activity, fineness of grind, and the chemical composition of the source rock. Precise performance is not easy to predict.

The preceding table was originally sourced from the website for ATTRA - National Sustainable Agriculture Information Service.

The numbers presented in this table should only be considered a rough guide to some manure based fertilizers such as bird and bat guano, who’s nutrient value often depends on a variety of factors.

heres another good 3lb content that has information on the time release of some common organic ferts

enjoy

You might enjoy these pre-prohibition studies- even though they were trying for male plants for the fiber. Their "failed" experiments are our "successes!

DON'T overdo it! If you're planning to add things such as blood/bone/feather meals, guanos, etc., to your soil, be sure you're measuring out how much needs to be added per square foot... don't just wing it, it can lead to disaster. A lot of people think that organic gardening is completely forgiving when it comes to feedings or soil amendments. Growing organically is more forgiving than lots of the chemical fertilizers on the market, but it can still be overdone. I started a thread about one of my horror stories working with organics here: Biggest Growing Mistakes...
