Options for Organic Growers
Some are nitrogen only others are nitrogen dominate ratio
Blood Meal
Fish
Bat Guano
Manure

Blood Meal
Blood meal, is a by product of the slaughterhouse industry waste
This is one of the highest concentrations of nitrogen from a non-synthetic source.
Even though this is organic it can be over applied which can result in burning plants due to the excessive ammonia.

Different Types of “Fish” Fertilizer
Fish Emulsion
Hydrolyzed Liquid Fish
Fish Meal
Fish Powder

Fish Emulsion
Infamous for its foul smell, emulsions are soluble, liquid fertilizers that have been heat and acid processed from fish waste.

Hydrolyzed Liquid Fish (Enzymatically Digested)
Enzymatically digested hydrolyzed liquid fish products use enzymes to digest the nutrients from fish wastes instead of using heat and acids. This retains more of the proteins, enzymes, vitamins and micronutrients than emulsions.

Fish Meal
Fish meal is ground and heat dried fish waste.

Fish Powder
Fish power is dried with heat and turned into water-soluble powder. It is a high source of nitrogen. Many can be mixed into solution and injected into an irrigation system.

Bat Guano
Bat guano (feces) harvested from caves and is a powdered product.
The powder can be applied directly to the soil or mixed with water, so it can be added to irrigation water for delivery to the plants.

Manure
Manure from cows, sheep, poultry, and horses are typically used as soil amendments.
Manure contains nitrogen, and because of this it is often the main reason for adding manure to soil.
While manures nutrient content is small compared to chemical fertilizer it can also help improve soil structure.
Keep in mind that the nutrient values will depend on the source animal and type of bedding used (and amount included).
