What Is Urea Fertilizer? Uses, benefits and importance in farming

When it comes to increasing the produce without harming the soil, urea fertilizer is one of the best options farmers have. The use of urea fertilizer increases production while supporting excellent soil health. Let’s learn more about it today. 

What Is Urea Fertilizer?

Urea is a nitrogen fertilizer. This fertilizer is dry, white granules high in nitrogen content. Pure urea contains 46% nitrogen, hence the name 46-0-0 fertilizer.

It is very powerful in providing nitrogen in a small amount. It is convenient for transportation and storage, and it is effective when used on time.

Types of Urea Fertilizer Used in Agriculture

The following urea fertilizers are used for agricultural purposes:

• Prilled urea: The particles in prilled urea are small and round in shape and dissolve very quickly when dissolved in water. This type of urea fertilizer is very popular for widespread use in field crops.
• Granular urea: The fertilizer granules in granular urea fertilizer are bigger and harder to crush. This fertilizer works better with heavy agricultural equipment because it is easier to distribute evenly.
• Coated urea: This urea fertilizer uses coatings made from sulfur and polymers that minimize the escape of nitrogen into the atmosphere. Thus, coated urea enhances fertilizer efficiency.
• Neem-coated urea: This type of fertilizer is commonly used in India to reduce the loss of nitrogen from the air and to protect the crops from insects without using pesticides.
• Urea solution: Urea solution is a solution form of urea that is used for precise distribution using the modern techniques of overhead spraying, foliar fertilization, and drip irrigation.

How Urea Fertilizer Helps Crops Grow?

The urea fertilizer contains nitrogen. Nitrogen forms the green pigment called "chlorophyll" used by the plants to make their food. It:

• Produces the proteins and DNA necessary for rapid plant growth and heightening and strengthening stems as well as the formation of leaves.
• Facilitates production of the green pigment used to absorb sunlight, hence enhancing the photosynthesis process.
• Promotes massive grain filling, tillering, and fruit production, leading to a greater yield at harvest time.
• Fulfills fast nutrient absorption in order to overcome stunted growth and revive the yellowing leaves affected by nitrogen deficiency.

What Are the Uses of Urea Fertilizer in Farming?

Urea fertilizer is used in many ways on the farm.

• Basal application before sowing to supply essential initial nitrogen to the soil 
• Top dressing after crop establishment to broadcast nitrogen onto the growing field
• Split application in wheat, paddy, and maize to maximize nutrient absorption 
• Fertigation in suitable irrigation systems to feed nutrients directly to the root zone 
• Nitrogen correction when plants show deficiency
• Utilized as a non-protein nitrogen supplement in ruminant animal feed 

For best results, apply urea when soil has moisture. Do not throw it on dry soil and leave it exposed. Mix it into soil where possible. In standing crops, irrigate after application if rain is not expected.

What Are the Benefits of Urea Fertilizer?

Rich in nitrogen. Since urea has 46% nitrogen content, a single bag of it will cover a greater surface area than those with less nitrogen content.

• Dry granular fertilizer. This means that urea fertilizer can easily be transported.
• Suitable for use in large and small farms
• Easy to apply manually or mechanically
• Has a neutral pH level and therefore can fit any kind of soil or crop easily.
• Non-explosive and very stable in warehouse storage conditions.
