Benefits of Calcium Nitrate as Fertilizer


Even the best gardeners need a little help from time to time. Calcium nitrate fertilizer is often used to grow more giant vegetables and more robust and faster plants. This soil or leaf additive can boost your plants and make them more productive while preventing some of the most common plant problems, like blossom-end rot and rust spots. Calcium nitrate is a well-kept secret in some ways. We are among the best calcium nitrate granules suppliers and sodium lauryl ether sulfate suppliers.

What is a Fertilizer Made of Calcium Nitrate?

If you’ve never used calcium nitrate fertilizer before and want to know more, this article will explain what it is, if it’s good for your plants, and how to use it.

Calcium Nitrate Fertilizer:

Calcium nitrate fertilizer is a chemical solution that dissolves in water and gives extra calcium and nitrogen to plants. These things are the biological building blocks that make plants strong and resistant to disease.

Calcium nitrate is not found in nature. It is made by mixing inorganic calcium and nitrogen. To do this, mix limestone with nitric acid and add ammonia. Most of the time, farmers use calcium nitrate fertilizers to help their crops grow better. But this doesn’t mean a home gardener can’t or shouldn’t use calcium nitrate on their fruits, vegetables, and houseplants.

Effects of Calcium and Nitrogen on Plants:

Calcium gives the cell walls of plants their strength. This part also helps plants heal when hurt or under stress. The plant’s vascular system will send calcium to the damaged area to strengthen it and start to fix the damage.

Nitrogen is an important part of photosynthesis and amino acids in plants. Without nitrogen, plants can’t turn light into sugars they need to grow.

Why Use Fertilizer with Calcium Nitrate?

As a gardener, you know that dirt gives life to your plants. Plants get their nutrients from the soil, but if the soil lacks enough nutrients, the plants get sick. The effects of these problems can be very bad.

Calcium nitrate fertilizer can help plants that are missing something or are sick. Here are a few common ways to use it:

For Calcium-Deficient Plants

Calcium nitrate fertilizer can keep a plant from getting too little calcium or give it more calcium. The boost in calcium it provides helps improve leaf strength, fruit, and roots.

How to Identify Deficient Plants:

It’s pretty easy to tell if a plant doesn’t have enough calcium. When a plant doesn’t get enough calcium, the edges of its new growth look like they are curled. This new growth also gets brown spots called “chlorotic” and looks worn out. Soon, other parts of the plant will start to brown, and these spots will grow and join together. Plants that don’t get enough calcium often have dark brown veins in their leaves, too. If a plant doesn’t have enough calcium, its leaves will turn brown and die. But the plant can be saved.

Lack of calcium also makes it hard for a plant to make fruit. Because calcium makes cell walls strong, it is an important part of making bigger fruit that doesn’t split.

For Nitrogen-Deficient Plants:

Calcium nitrate will give plants a dose of nitrogen that they can use to make more energy.

A lack of nitrogen can kill plants just like a lack of calcium if it isn’t fixed in time. Because of this, nitrogen is one of the most common and common fertilizer ingredients.

How to Identify Deficient Plants:

Unlike calcium deficiencies, nitrogen inadequacy affects a plant’s oldest foliage. Most of the time, these are the leaves at the bottom of a plant. When a plant doesn’t get enough nitrogen, the edges of its leaves will start to turn yellow or fade. If the plant is still making new leaves, they will probably be small or look like they have shrunk.

A plant’s growth slows or stops if it doesn’t get enough nitrogen. This is because plants can’t make energy through photosynthesis without nitrogen. In photosynthesis, plants use nitrogen to turn energy from the sun into usable forms.

To Keep from Getting Sick:

One of the main reasons why many gardeners use calcium nitrate fertilizer on their plants is to keep them and their crops from getting sick. Calcium nitrate fertilizer can be used to stop or treat blossom end rot, cork spot, and bitter pits in apples.

Blossom end rot is a common problem for people who grow tomatoes. It looks like wet spots on the bottom of the fruit. Blossom end rot will make a tomato look bad and make it impossible to eat. The fruit will get flatter and look hard and leathery as it grows. It is usually caused by insufficient calcium; a calcium nitrate foliar spray works well to treat it. You can also add a calcium nitrate fertilizer to your soil to help stop blossom end rot from happening again next growing season.

Common Problems:

Cork spots and bitter pits are problems that can happen to apples. Both of these problems can be caused by a lack of calcium. Cork spot-on apples usually start appearing in June and worsen over the summer. The problem appears as discolored holes in the fruit, which can be of different sizes. Even though they don’t change the taste of the apple, they make it look bad. Bitter pit presents itself as pockmarks on the skin of the apples and causes brown spots on the fruit’s flesh.

Like cork spot, bitter pit makes the fruit look unappealing, but it doesn’t affect the taste like cork spot does. Apples with bitter pit will have a bitter flavor, and though they will still be perfectly safe to eat, you will probably want to avoid them. These issues are caused by insufficient calcium and can be fixed with calcium nitrate fertilizer (SF Gate).

For Tomatoes:

People often say tomatoes are the most common plants to get blossom-end rot from insufficient calcium. Many home gardeners have checked their newly developing tomatoes to find small brown spots that quickly spread and ruin their crop. Making a calcium nitrate spray can stop blossom-end rot from happening again and help tomato plants recover.

Pros and Cons of Calcium Nitrate Fertilizer:


Helps plants grow stronger by stopping problems before they happen.

Boosts the size of the fruit plants can make.


You can’t say that the food you grow at home is organic.

Getting the levels right for plants that grow in the ground can be hard.

Can change the pH of your soil a little

How to Grow Plants with Calcium Nitrate

If you want to take your tomatoes, peppers, eggplants, and other vegetables to the next level with calcium nitrate fertilizer, pay close attention to how you mix and apply it. Here, you can learn more about how to make calcium nitrate fertilizer, put it on plants, and store it.

Recommended Rate of Application:

Mix four tablespoons of calcium nitrate salts and one gallon of water to make your calcium nitrate fertilizer. This can be used to treat sick plants. Add one tablespoon of calcium nitrate to each gallon of water to use it as a disease preventative or to ensure your plants have the right amount of nutrients.

If you buy calcium nitrate in the form of granules, you can mix it into the soil. You could also mix your granular calcium nitrate with water and feed your plants that way or through a leaf spray.


Even if you don’t have instructions, it’s easy to figure out how to make a calcium nitrate spray from granules:

  • One gallon of water with two to four tablespoons of calcium nitrate
  • Shake the bottle well until most of the salt has dissolved.
  • Label your gallon to prevent confusion
  • Fill a spray bottle with enough to treat your plants.
  • After using it, put it away at room temperature.
  • One tip for people who want a green thumb is to put one tablespoon of calcium nitrate on each plant that is about average size.

Dressings with calcium nitrate. If you want to put your fertilizer on the side or top, you must use. 10 of a pound of soil for every 10 feet.

How to Use the Fertilizer Calcium Nitrate:

Calcium nitrate can be put on plants in three ways: as a spray on the leaves, a top dressing, or a side dressing.

  1. Spray on Foliage. 

This is the best way to fix cork spot, bitter pit, and blossom-end rot. First, take the bad fruits away. Spray the plant’s leaves and stems lightly on a cloudy day or evening when it is not as hot.

  1. Best Dressed. 

Add some topsoil to your calcium nitrate fertilizer. Spread a thin layer of this mixture over the soil around your plant or where you plan to plant. Do not put it right on the trunk or stem.

  1. Side Dressing. 

Most of the time, this is used when your plants are in a row. To side-dress, your plants, sprinkle an even layer about two to five inches away from the stems.
