Sources of Nitrogen (Organic)
Updated: Mar 12, 2022
When dealing with fertilizers, the three numbers you will see represents the value of the three macro-nutrients used by plants known as the NPK value. The (N) represents NITROGEN and is largely responsible for the growth of leaves/vegetation on the plant. Below are the top picks of organic nitrogen sources...
-FISH EMULSION, also known as liquid fish fertilizer, is an organic fertilizer made from whole fish or fishing industry byproducts like fish scraps, fish oil, and fish meal. Excellent source of Nitrogen with an average NPK of 4-1-1. Grab a bottle of Fish Emulsion but cover your nose when applying!!
-BLOOD MEAL: While also serving as a deterrent to certain garden "pest" like rabbits, deer, and squirrels, blood meal is byproduct of (usually) livestock production which is merely dried, inert blood that is HIGH in nitrogen content. All things considering, it is one of the BEST organic sources available. Espoma is a highly trusted source for a QUALITY product so grab your Blood Meal here.
-FEATHER MEAL is a byproduct of processing poultry; it is made from poultry feathers by partially grinding them under heat and pressure, then completing the grinding and drying. Although nitrogen levels are fairly high, the bioavailability of this nitrogen may be low; Meaning the nitrogen will become available to plants slowly overtime. DOWN TO EARTHs Feather Meal is exactly what you're looking for!
-BAT GUANO is simply the accumulated excrements of bats. As a manure though, it is a highly effective nitrogen source as well as the other two macro nutrients (phosphorus and potassium) and can be applied as is or brewed to make a liquid fertilizer. Do not blindly (bat pun) search for a quality source; Mother Earth has you covered on Bat Guano here.
-NEEM SEED MEAL in addition to its high nitrogen content, neem seed meal Is typically used for its ability to protect against parasitic nematodes and soil borne pest insects like fungus gnats and roots aphids. This is made from cold pressed neem seeds and is also known as Neem Cake.
grab a box of DOWN TO EARTHs Neem Seed Meal.
-SOYBEAN MEAL another slow release, organic fertilizer made from soybeans that are ground, dried and heated to extract the oil and the solid residual (the meal). Primarily used as animal feed due to protein levels. Often reaching levels of 7% Nitrogen in fertilizers, it's clear this is a needed tool in a farmer's arsenal. BE CAREFUL, soybean meal can inhibit the germination of small seeds so use as top dressing only after plants have established themselves. 3rd times a charm with DOWN TO EARTHS quality Soybean Meal.
-COTTON SEED MEAL is the byproduct remaining after cotton is ginned and the seeds crushed, and the oil extracted. The remaining meal is usually used for animal feed (adult livestock) and in organic fertilizers. It's an organic fertilizer that lowers the pH of soil (great for acidic condition loving plants like azaleas and blueberries) and provides loads of nitrogen. Get your Cottonseed Meal here.
-(FARM) ANIMAL MANURE From chickens and cows to goats and rabbits, manure is an excellent all-natural fertilizer that can enrich the soil with nutrients and encourage a healthy soil biology. Som manures are cold (not necessary to compost or age) and can be applied directly in the garden. Others are considered hot and though very high in nitrogen, have the potential to burn your plants; let compost/age first. While if you have animals, you can utilize their excrements, there are products you can obtain like Espoma's Chicken Manure or the infamous Black Kow Cow Manure.
