Nitrogen is a crucial nutrient for healthy lawns and gardens. It helps to promote lush and green growth in grasses and other plants by providing essential nutrients that help them grow strong roots, stems, and leaves. Nitrogen also plays a vital role in photosynthesis, converting sunlight into plant energy. Without nitrogen, your lawn would be dull and lifeless. This article will discuss everything you need about what nitrogen does for lawns, including how it works, when to apply it, what type of fertilizer to use, and more! With this information, you can set up a fertilization plan to keep your lawn looking its best all year round!
What Is Nitrogen?
Nitrogen is a colorless, odorless gas found on Earth and throughout our universe. It has an atomic number of 7, meaning it has 7 protons in its nucleus, and its most stable form contains 14 neutrons.
While it is one of the most abundant elements on earth, nitrogen only makes up 4% of the Earth’s crust. Fortunately, plants have evolved to take advantage of this resource by “fixing” atmospheric nitrogen into other forms that are more accessible to plants and animals.
Common Sources Of Nitrogen
Nitrogen is essential for life on Earth, with 78% of the atmosphere being nitrogen. It is a crucial nutrient for all living things, from plants to animals to humans. But where does nitrogen come from? In this blog post, we’ll explore some familiar sources of nitrogen and how it’s used in various parts of nature.
The Atmosphere
Nitrogen gas (N2) makes up 78% of the Earth’s atmosphere. Although it is present in high concentrations, N2 is relatively inert and not readily usable by most organisms. As such, it must be converted into other nitrogen compounds before living things can use it. This process is known as nitrogen fixation, and it can occur naturally through lightning strikes or through the activity of specialized bacteria and archaea found in soils and aquatic environments. These microorganisms convert nitrates into ammonia, which plants or animals can then take up as a source of nutrition.
Inorganic Sources
Inorganic nitrogen sources are any mineral or synthetic compounds that contain nitrogen in an elemental form. These include ammonium nitrate, urea, and calcium nitrate, among others. In addition to being found naturally in the environment, these compounds can also be manufactured synthetically and used as fertilizers on turf grasses and other plants in lawns and gardens.
Organic Sources
Organic sources of nitrogen are compounds that contain C-H bonds in addition to N-H bonds. These typically come from animal waste, composted plant matter, or processed food products like breakfast cereal. This type of nitrogen is typically available for plants immediately after application, as the complex molecules can be easily broken down into simpler nitrogen compounds.
Organic sources of nitrogen are typically considered more sustainable than inorganic sources, as they recycle nutrients back into the environment instead of releasing them into the atmosphere or water systems.
Which Are The Main Nitrogen Fertilizers?
The main nitrogen fertilizers available today are urea, ammonium nitrate, and calcium nitrate. Urea is an organic compound commonly used as a fertilizer or soil amendment. It contains 46% nitrogen and can be applied to the soil surface or incorporated. Ammonium nitrate (NH4NO3) is an inorganic compound composed of nitrogen and oxygen.
It contains 34% nitrogen, is highly soluble in water, and can be used as a fertilizer or soil amendment. Calcium nitrate (Ca(NO3)2) is an inorganic compound composed of calcium, nitrogen, and oxygen. It contains 15-17% nitrogen and has moderate solubility, making it a popular choice for dry and liquid fertilizers. When to Apply Nitrogen
It is recommended to apply nitrogen fertilizer before the growing season begins, usually in late winter or early spring. This ensures that your lawn has enough nutrient reserves for the upcoming season of growth. It can also be applied throughout the growing season to give your lawn a boost of nutrients whenever needed. Additionally, applying nitrogen fertilizer at the end of the growing season can help promote fall color and strengthen root systems for winter dormancy.
How Much Fertilizer Is Enough?
When applying nitrogen fertilizer, it is important to follow the instructions on the product label and be careful not to over-fertilize. Applying too much nitrogen can lead to excess growth, increased susceptibility to diseases and pests, and runoff of nutrients into nearby water systems.
It is best to start with a low application rate when fertilizing your lawn and only increase the rate if needed. Generally, a good rule of thumb is to apply no more than 4 pounds of nitrogen per 1000 square feet in any given year.
Overall, nitrogen fertilizers are important in maintaining a healthy lawn or garden. By understanding the different types of fertilizer available and when and how to apply them, you can ensure your plants get the nutrients they need to thrive.
When should you put nitrogen on your lawn?
The best time to apply nitrogen fertilizer to your lawn is typically in late winter or early spring before the growing season begins. This will ensure that there are adequate nutrient reserves for the upcoming period of growth.
Nitrogen can also be applied throughout the growing season and at the end of the growing season to promote robust root systems and fall color. It is essential to follow the instructions on the product label and not over-fertilize, as too much nitrogen can lead to excess growth and runoff into nearby water systems.
A good rule of thumb is to apply no more than 4 pounds of nitrogen per 1000 square feet in any given year.
Following these guidelines can help ensure your lawn is healthy and vibrant all season long.
How do I know if my lawn needs nitrogen?
The best way to determine if your lawn needs nitrogen is to do a soil test. A soil test will measure the amount of nitrogen already present in the soil and other essential nutrients, such as phosphorus and potassium.
If the results show that your lawn has an inadequate nitrogen level, you may want to consider applying a fertilizer with nitrogen. If the results indicate adequate nitrogen in the soil, you may not need to apply additional fertilizer.
When deciding if your lawn needs more nitrogen, it is also essential to consider other factors, such as the type of grass, watering schedule, and mowing practices. With careful observation, you can help ensure your lawn gets the nutrients it needs to stay green and healthy.

When and how much nitrogen should you apply to your lawn?
The best time to apply nitrogen fertilizer is usually in late winter or early spring before the growing season begins. This will ensure that there are adequate nutrient reserves for the upcoming period of growth. Nitrogen can also be applied throughout the growing season and, in the end, promote robust root systems and fall color.

A good rule of thumb regarding fertilizer application is to apply no more than four pounds of nitrogen per 1000 square feet in any given year.
What does the grass look like when it needs nitrogen?
When a lawn lacks nitrogen, it can often appear yellow or light green and have stunted growth. It can also become more susceptible to diseases, weeds, and pests. Regularly monitoring the health of your lawn is essential so you can spot potential problems early on and apply an appropriate fertilizer before any damage occurs.
These tips and recommendations can help ensure your lawn or garden is healthy and vibrant all season long.
The key to successful fertilization is understanding the available fertilizer types, when to apply them, and how much to use.
