What are your options with organic fertilizers?

Turns out there are quite a few good ones. For the gardener new to the idea of organics, the array of options often made available can be confusing. There are dozens of organic natural fertilizers available, each with different characteristics and ease of use and not all having convenient labels with simple how-to information to go with them

List of Organic Fertilizers

Alfalfa Meal 

2.5% N, 1% P, 1.5% K
Slow to moderate
Best known as a “hay” for animals, the meal is one of the plant-based fertilizers. It is just ground-up alfalfa that makes it compost faster in the soil. Best tilled in as an early spring additive, well before planting.

Bat Guano | Buy Organic Fertilizers from wholesalers

8% N, 6% P, 1% K
Moderate to immediate
The most common source of guano, bat guano is relatively fast in uptake and so is often used between crop rotations (mid-summer harvest / replant) or in late spring just before planting. Bird guano has higher nutrition numbers, but seabird guano is only available in a few parts of the world.

Fish Emulsion | Buy Organic Fertilizers from wholesalers

9% N, 0% P, 0% K
Immediate
This is a great additive when nitrogen levels are low and leafy plants need a good boost. Fish fertilizer is slightly acidic, so some plants may not tolerate it as well as others.

Cotton Seed Meal | Buy Organic Fertilizers wholesale

6% N, 3% P, 1% K
Slow
A common plant fertilizer in areas where cotton is grown, this is a favored year-end, pre-winter mix. Adding it to the soil before cover crops or mulch are put on gives a rich nitrogenated soil in the spring.

Corn Gluten Meal 

0.5% N, 0.5% P, 1% K
Slow
Another common late-season, winter preparation additive, corn gluten is a good soil stabilizer for winter.

Seaweed

1% N, 2% P, 5% K
Fast
Also a great source for zinc and iron, seaweed is one of the most beneficial organic fertilizers that are freely available on the coasts. Cereal grains and other high-potash crops can especially benefit from seaweed.

Cow Manure

2.5% N, 1% P, 1.5% K
Moderate
Probably the most common organic fertilizer in use in the western world, cow manure is comparable to good compost in nutrient value and uptake. It may contain weed seeds, but is otherwise a gardener’s best friend. Avoid manure from dairies and other industries where the cattle receive a lot of salt.

Chicken Manure(Poultry)

3.5% N, 1.5% P, 1.5% K
Fast
Another of the animal manures, poultry manure is often used in agriculture when organic growing needs a quick boost. Most often, poultry manure is added after harvest and before a second planting.

Greensand

1% N, 1% P, 5% K
Moderate
Literally ground up green limestone, it’s a shallow marine sediment and thus full of the richness that the lakes and oceans can offer. The amount of nutrient depends heavily on the source of the sand.

Compost

2% N, 1.5% P, 1.5% K
Moderate
Compost’s actual contents are highly variable and dependent on what was used to make them. The best compost is a roughly even mix of the big three essential nutrients and can produce somewhat alkaline soil. Often added before planting, in-between plantings, or at the end of the growing season. Rough compost can also be used as a beneficial mulch. Also, try worm composting and making compost tea.

Soybean Meal

3% N, 0.5% P, 2.5% K
Moderate
Uptake will depend heavily on conditions, but in general, soybean meal is a good additive for longer-lasting results during soil maintenance.

Blood Meal

12% N, 1.5% P, 0.5% K
Fast
While acidic, blood meal is a very fast “booster” for nitrogen-hungry plants or plants suffering from deprivation of organic compounds. Is most often poured directly over the plant roots and then covered in mulch.

Bone Meal

4% N, 20% P, 0% K
Moderate
This is most often used in situations with poor soil quality where the soil requires serious amendment to bring it up to par. Soils that routinely show high amounts of nitrogen or that produce nitrogen-burnt plants benefit from bone meal.

Feather Meal

12% N, 0% P, 0% K
Moderate
Another nitrogen booster, this is most often used pre-season, before planting, to “pump up the soil” before garden plants go into it.

Fish Meal

10% N, 5% P, 4% K
Fast
A fast uptake for a balanced boost of all nutrients is had with fish meal. There’s a reason Native Americans planted a fish at the base of their corn plants in popular legend.
