As any gardener knows, it’s important to feed your plants the nutrients they need to grow. Plants need nitrogen in order to produce chlorophyll and other compounds that make them green. But what is organic nitrogen fertilizer, and how can you use it to best improve your garden? In this article, we’ll cover why plants need nitrogen in general as well as some of the different types of organic fertilizers available for growing vegetables or other plants.

Nitrogen is one of the three essential nutrients in the soil. It’s the most important nutrient for plants and it helps them grow. When your plants don’t have enough nitrogen, they can’t grow properly or produce good yields. That’s why you need to apply nitrogen fertilizer every year.

Organic nitrogen fertilizers are made from plant-based materials such as compost and manure, which are considered “natural” sources of nitrogen because they come directly from Mother Nature. Unlike synthetic fertilizers, organic fertilizers are not chemically processed and have no harmful chemicals added during the production process; so they are safe for humans and animals alike. Plus, they work just as well if not better than synthetics because they contain all of their natural nutrients, whereas synthetics only contain part of what an organic fertilizer would contain (e.g., nitrates vs. nitrites).

What is an organic nitrogen fertilizer?

If you’re looking for a way to increase the nitrogen content in your soil, consider adding organic nitrogen fertilizer. Organic nitrogen fertilizers are made with natural substances such as animal manure, fish emulsion, and alfalfa meal. They can be used in combination with synthetic-based products to achieve optimum results.

The primary difference between organic and synthetic fertilizers is that they use different sources of nutrients. Synthetic fertilizers rely on synthetic chemicals while organic fertilizers rely on natural substances like manure, fish emulsion, or alfalfa meal (to name a few). You may also hear people refer to these types of products as organic or chemical fertilizers; however, it’s important not to confuse these two terms because they describe completely different things.

Why do plants need nitrogen?

Nitrogen is an essential nutrient for plants. It’s a component of proteins, which are necessary for plant growth and development, as well as chlorophyll, the green pigment responsible for photosynthesis, the process by which plants convert carbon dioxide and water into sugars. Nitrogen also plays a role in DNA and RNA synthesis.

How do you know when to fertilize your garden?

The best time to fertilize your garden depends on the type of vegetable you are growing. Most vegetables need at least one feeding per season.

  • Leafy greens (lettuce, spinach, kale) should be fertilized every two weeks.
  • Root vegetables (carrots, beets) need to be fertilized every four weeks or so during the growing season.
  • Fruiting vegetables (tomatoes and peppers) also need at least one feeding per season; however, they may require more frequent fertilizer applications throughout the summer months depending on their size and development stage at planting time

How to apply organic nitrogen fertilizer for vegetables

  • You can use organic nitrogen or fertilizer in the spring and fall.
  • Organic nitrogen is an excellent source of nutrients for your vegetable plants, but it’s important to know how to use it properly. Organic fertilizers are slow-release, meaning they’ll be available throughout the season rather than all at once like synthetic fertilizers. It’s important that you know when to apply them so that they have time to break down into their component parts before being taken up by the plants. While different types of organic fertilizers work differently based on their chemical composition and mineral content, there are some general guidelines you can follow.
  • Apply liquid organic nitrogen fertilizers during periods of active growth in early spring and again in late summer through fall when plants are actively producing fruits or vegetables; don’t apply them after harvest has ended.

Organic fertilizers and the nitrogen cycle

Plants need nitrogen to grow, but how do plants get it? Nitrogen is a gas that makes up about 78% of the air we breathe. Microorganisms in the soil convert the nitrogen in the air into nitrates, which is a form of nitrogen that can be readily used by plants. Most plants obtain their nitrogen through their roots and soil microbes, but some species have developed symbiotic relationships with certain types of fungi or bacteria that provide them with this crucial nutrient.

Plants use proteins as a structural material for their structural tissues (such as leaves and stems) and enzymes (the chemical catalysts involved in many biological reactions). These proteins are made from amino acids, and there are 21 types of amino acids found in nature. Some plants can synthesize most of these on their own; however, most legumes (peas and beans) cannot make all 21 amino acids on their own and rely on symbiotic relationships with specific fungi or bacteria for at least nine out of eleven essential amino acids needed for growth

1. Alfalfa meal

Alfalfa meal is a by-product of alfalfa hay. It contains over 60 nutrients and is high in nitrogen, phosphorus, potassium and calcium. It also contains trace minerals such as zinc and magnesium.

2. Blood meal

A blood meal is a nitrogen-rich organic fertilizer. It’s made from the dried and powdered blood of livestock that has been slaughtered for their meat. Since it’s a byproduct of the food industry, it can be surprisingly inexpensive to buy. A blood meal is available in bags or bulk bins from many garden stores, but you may also find it at pet supply stores or farmers’ markets if you want to buy local products.

A blood meal is easy to apply as long as you don’t mind getting a little bit messy. Simply sprinkle or broadcast (throw) it over your soil surface before planting time and then work it into the top few inches of soil with a shovel or tiller, just make sure not to add too much because too much nitrogen will result in fast growth but poor root development. Ideally, though, you should add only one tablespoon per square foot of garden space every four weeks during peak growing season (mid-spring through mid-summer).

3. Cottonseed meal

Cottonseed meal is a by-product of cottonseed oil extraction. It is rich in nitrogen, phosphorus, and potassium and also high in amino acids, which are important for plant growth.

It’s a great source of slow-release nitrogen because it contains lignin, a material that binds the nutrients together and allows them to be released over time.

4. Feather meal

Feather meal is a nitrogen-rich organic fertilizer that’s often used to boost the nutrient levels in organic gardens. It provides most of the essential nutrients for your plants, including nitrogen, phosphorus, potassium, calcium, and magnesium.

In addition to its impressive nutrient content, feather meal also contains sulfur, an important micronutrient that plays a key role in many plant processes such as photosynthesis and respiration. Sulfur is typically added to synthetic fertilizers as well but can be hard on certain vegetable plants, like broccoli or cauliflower, due to its toxicity at higher concentrations

5. Fish meal

Fish meal is a good source of nitrogen, and also contains phosphorus and potassium. It can be used to fertilize your vegetables, but you should use it sparingly because it’s high in salt. Fish meal is an excellent source of protein, with one pound containing up to 40% protein content. Fish meal is also an excellent source of vitamin B12 (important for the health of all animals), as well as other vitamins and minerals that plants need.

6. Urea

Urea is a solid, crystalline organic compound that is widely used in fertilizers as a nitrogen source. Urea is produced by combining ammonia and carbon dioxide with water. Urea itself does not break down easily and must be broken down into ammonium salts or nitrates before it can be absorbed by plants.

Urea is a nitrogen-rich compound that is used to make fertilizer. This fertilizer breaks down quickly when applied so it should only be used on garden crops when they need extra nutrients to grow well at the beginning of the growing season, such as after transplants are planted outdoors or if you’re starting seeds indoors and transplanting them outside once they reach maturity

7. Bat Guano

Bat Guano is an excellent source of nitrogen and is a sustainable source of fertilizer. It also contains phosphorus, potassium, and trace minerals as well as humic acid. Humic acid is an important component used in organic fertilizers to help plants absorb nutrients.

Bat guano provides the same benefits to soil as other types of animal manure but with less smell because it does not decompose easily or lose its nutrients quickly due to its high carbon content (20% to 50%). This makes it a good choice for long-term use on your vegetables.

8. Kelp Meal/Seaweed Extracts

Kelp meal is a good source of potassium and trace minerals, making it ideal for vegetables that require higher levels of these nutrients. Seaweed extracts are rich in plant growth hormones, which help plants grow faster. Seaweed has been used as fertilizer for centuries because it’s a great source of micronutrients such as iron, zinc, copper, and manganese (which we mentioned earlier). These supplements can be added to the soil or sprayed on topsoil before planting gets underway.
