5 Amazing Uses of Urea Fertilizer | Must Read

If you want to know about the uses of urea fertilizer, you will love this detailed guide. But first, I have a question for you. What is a fertilizer?

Let me help you answer this question. We use fertilizers to improve our crop yield (growth). In simple words, fertilizer is a substance that increases the fertility of soil or land.

Now, let me introduce urea to you.

Uses of Urea Fertilizer:

You should know that urea is a crystalline and colourless substance. Now, I have a question for you. Where else is urea used apart from fertilizers?

It is used as a feed supplement, and also in the manufacture of drugs and plastics.

Now, let’s talk about urea as a fertilizer.

Overview: Due to its high nitrogen content, urea causes green leafy growth of your plant. Moreover, it contains around 46% Nitrogen. Note that Chlorophyll uses Nitrogen as a mineral to carry out photosynthesis.

Due to its high nitrogen content, it is a commonly used nitrogenous fertilizer. The best part is that this nitrogen content is readily converted to ammonia in the soil.

Quick fact: Do you know that around 80% of the annually produced ammonia is used for fertilizer production? Pretty cool, isn’t it?

Now, here are some uses of the urea fertilizer:

  • The high nitrogen content promotes the green leafy growth of the plant.

This simply means that your plants look lush. You should know that this is NOT done by urea directly. Let me explain.

First of all, an enzyme (a biological catalyst that speeds up a reaction) in the soil and plant residue converts urea to nitrogen. This nitrogen is then used by the plants.

Over here, I want you to know that urea has around 46% nitrogen content. Pretty high, isn’t it?

  • It is non-flammable. This makes its storage risk-free.

This simply means that they do not catch fire easily. Here’s some quick math to help you understand this.

Urea melts around 132.7° C (271° F). Plus, it decomposes before boiling. This is the reason why urea-based fertilizers melt around 535° Fahrenheit.

  • The process of Photosynthesis is favoured.

Can you recall what exactly is photosynthesis? This is a process by which plants make oxygen and energy in the form of sugar. They do this by using carbon dioxide, water and sunlight.

Now, here’s the thing.

In plants, there is a green pigment known as Chlorophyll that allows plants to carry out photosynthesis. Well, this green pigment uses Nitrogen as a mineral to do so. Can you recall where this Nitrogen comes from?

  • It is harmless for plants and the most eco-friendly among nitrogen fertilizers.

Here’s why this is important.

It can be used as an anti-stress agent to improve crop quality. This can be done from autumn applications during tillage (preparation of land for growing crops.

  • Its efficiency is highest in water-demanding crops such as rice.

Let me explain.

Note that in irrigated crops. urea is added to the standing crop (a growing crop). This is followed by irrigation to minimise the loss.

In rain-fed areas, it is applied just before the rain to prevent loss through the volatilization process.

Note that the volatilization process refers to the loss of Nitrogen from the soil as ammonia gas. On the other hand, granular urea is easy to apply on standing crops because of its large size granules.

Now when you know about the uses of urea, here are some other things that you should know.

How to apply Urea fertilizer?

The way you apply a fertilizer can impact the growth of your plant. So let me teach you the perfect way of applying a fertilizer:

uses of urea fertilizer
  1. First of all, urea should be applied at the time when you are sowing the plant.

This is because fertilizers are most effective when plants are at their peak growing cycle.

  1. You should make sure that the fertilizer is applied to the soil evenly.

You can use a fertilizer spreader for this purpose. You can sprinkle the pellets or granules with your hand as well. Note that you can mix it with sand or mud as well.

  1. Now, you should make sure that the soil is wet. This is because ammonia gas can escape from the soil surface.

You have to be careful with water. This is because if urea is placed in the soil which has free water, it can degrade your plant growth.

Summary: After adding the granules, the soil should be immediately watered. This is because if it is left on the surface, the nitrogen content may be lost as gases.

Note that even 1-2 inches of water in the soil is enough for the plant to use it.

With this, it is time to talk about some disadvantages of urea.

Disadvantages of urea:

Here are some things that you should know.

  • Excess urea can damage the plant or crop.

As I mentioned above, there is a high nitrogen content in this fertilizer. Therefore, if we do not add them in the correct amount, the pH of the soil can be disturbed.

This is the case with all fertilizers. If we add them in excess, the content of organic matter in the soil can be reduced.

This can further lead to stunted (poor) growth of the plant and growing pests as well.

  • The process of volatilization can take place.

In simple words, volatilization is the loss of Nitrogen. This happens due to the conversion of ammonium to ammonia gas, which is released into the atmosphere.

disadvantages of urea fertilizer

You should know that this process is favoured by a higher soil pH and conditions that favour evaporation (e.g hot and windy).

But why does this happen?

This can happen due to the moisture and typically happens in the first seven to fourteen days after the fertilizer application.

Note that when the pH (acidity or alkalinity) increases from 6.5 to 7.5, the volatilization loss doubles. Pretty interesting, isn’t it?

  • If the impurities exceed 2%, it cannot be used as a fertilizer. This is because impurities are toxic to some crops.

FAQ’s About The Uses Of Urea Fertilizer:

Here are some of the most frequently asked questions.

What are the three common uses of urea?

As I mentioned above, it has a high nitrogen content that promotes the green leafy growth of the plant.

Moreover, the storage is risk-free and the process of Photysntheis is also favoured.

How many times to apply the urea fertilizer?

Most of the time, you should not apply more than 2 to 10 pounds of urea per acre. Or you can add 0.5 to 2.5 pounds per 100 gallons of water.

As we discussed above that the Nitrogen content can be lost as well, this is why it can vary as well.

Can you use the urea fertilizer on the lawn?

Yes, you can! Due to its high nitrogen content, it can work perfectly for your lawn. But, you should be careful with the amount that you apply to your lawn.

Roughly, one pound of this fertilizer per 1,000 square feet of the lawn should be added.
