Many people are interested in growing plants but some new gardeners don’t know much about what plants need.

You might have heard people mentioning that nitrogen levels are essential for plant health. This is true but you might not really know why plants need nitrogen as a newcomer to the hobby.

Why Do Plants Need Nitrogen? (And How To Tell When They Need More)

You can keep reading to get more information about plants and why nitrogen is so crucial.

This should help you to understand why nitrogen is something that you need to pay attention to. You’ll even be able to learn how you can adjust the nitrogen levels in the soil by making certain changes.

What Nitrogen Is

Nitrogen is one of the elements and it exists in the atmosphere of this planet.

Many living things on this planet need nitrogen to be able to survive.

Plants rely on nitrogen so that they can create protein and nitrogen can be found in soil as a nitrate that plants can use.

Why Do Plants Need Nitrogen So Much?

If you’re still wondering why nitrogen is so important to plants, then you should try to think of it in a different way.

Nitrogen is a substance that allows plants to maintain their health. If plants didn’t have access to nitrogen, then photosynthesis wouldn’t be possible.

You should also know that nitrogen plays a substantial role in the growth of plant cells and tissues. It even helps plants to be able to form chlorophyll.

You might have learned in science class that chlorophyll is what makes it possible for plants to receive energy from light.

Even the growth of reproductive cells would not be possible without nitrogen.

In essence, plants are very reliant on nitrogen for survival and this is why you have to pay attention to nitrogen levels in the soil.

If you want your plants to grow healthy, then it’s necessary to be mindful of how much nitrogen they have access to.

Many plants need a certain amount of nitrogen to be able to thrive. Too much nitrogen can often be a detriment as well similar to how watering a plant too much can be bad.

You have to be mindful of what is going on so that you can make good choices.

How Can You Know When Plants Need More Nitrogen?

There are a few ways to tell when your plants aren’t getting enough nitrogen. One of the more obvious ways is when your plants start to get yellow leaves.

Plants that are lacking enough nitrogen often have their leaves turn yellow and this eventually leads to more severe issues.

Yellowing leaves are a sign of something known as chlorosis and it basically means that your plants need more nitrogen so that it can sustain itself.

Sometimes your plant won’t give you as many obvious signs that the nitrogen levels are off, though. This might require you to do a soil test and these are actually pretty easy to do, so you don’t have to fret.

Soil testing is a method that many people do to get an idea of how the nitrogen levels look. Sadly, soil tests aren’t always completely accurate due to the fact that you’re only testing one part of the soil.

You can’t really soil test the soil throughout your entire garden and this makes it a less reliable metric than would be ideal.

It’s also possible that your plant could look rough even though it has enough nitrogen.

Many things can cause plant issues such as pests, watering the plant too much, too little water, too much sun, and more.

You’ll need to do your best to determine what is going on by paying attention while doing what you can to monitor the nitrogen levels to ensure that everything is fine there.

How Can You Give Plants More Nitrogen?

Nitrogen Fertilizer Bag

For the most part, adding nitrogen to the soil is about using the right type of fertilizer.

Depending on the needs of your plants, you might want to use a specific type of fertilizer. Some plants thrive with a lot of nitrogen and others might need a very specific nitrate level in the soil.

Many gardeners make their own fertilizer using things such as fish or bone meal but you can also buy commercial fertilizers to make things easier.

It’s actually pretty simple to get fertilizers from stores that are specifically meant for certain types of plants. You can look up information or get recommendations about what type of soil to use as well as what fertilizer will work out best.

You can make adjustments to the nitrogen levels using fertilizer and it should have an impact on your plants.

It can also be helpful to be mindful of what type of soil you’re using before you plant your garden.

Doing a bit of research can allow you to get the levels right from the beginning so that your plants can do well.

Take Care of Your Plants

Take care of your plants well and be mindful of nitrogen levels so that you can avoid problems.

When plants don’t have access to enough nitrogen, it’s going to be impossible for them to do what they need to do. You wouldn’t feel very well if you didn’t have water or food to eat and your plants need energy too.

Now that you have a good understanding of what nitrogen is and why plants need it so much, it’ll be easier for you to keep an eye on things.

You don’t necessarily have to possess a deep understanding of nitrogen on a scientific level to be an effective gardener. You just need to recognize the importance of nitrogen levels in the soil while knowing what to look out for.

Hopefully, this information will clear things up for you so that you can approach gardening with confidence.

It really isn’t that tough to look at nitrogen levels and you can adjust things when you need to do so. Buying the right fertilizer and knowing a bit about the nitrogen requirements of your plants will work wonders.
