46-0-0 Fertilizer must be handled with extreme caution, because it is a fertilizer with high, mostly nitrogen content.
In this post, we&#;ll cover what 46-0-0 Fertilizer is, its composition, its advantages, and disadvantages, how to use it, its types, and the best times to apply it to your farm, lawn, or garden for the best results. Keep reading to learn all about it.
46-0-0 Fertilizer is a urea fertilizer, a simple single-element fertilizer that provides the main necessary ingredient nitrogen in ammonic form (NH4+). One of the two forms of nitrogen plants can take the positively charged, non-volatile ammonium ion (NH4+), the other being nitrate (NO3&#;).
With so many alternatives available, finding the Fertilizer that your plants require can seem time-consuming, but when you comprehend the labeling, choosing the appropriate one is simple.
Most labels mention the item&#;s NPK (how much nitrogen, phosphorus, and potassium the product contains). It will be pure nitrogen in 46-0-0 Fertilizer.
All incorporated secondary micronutrients, such as calcium, magnesium, and others that promote plant health, should be listed on the back label. Its N-P-K ratio of 46-0-0 Fertilizer is 46 nitrogen, zero percent phosphorus, and zero percent potassium.
The remaining ingredients are additives or fillers that help make the product application easier. When applied correctly, a 46-0-0 ratio can assist in converting nutrient-poor soil into a beneficial growing medium.
For general plant health, it will be necessary to provide enough phosphorus, potassium, and other micronutrients after planting.
Nitrogen encourages the production of chlorophyll, which promotes healthy foliage growth. Chlorophyll, which gives plants their green color, ensures that the energy gathered is converted into food by breaking down starches and carbohydrates.
Proteins and enzymes that control the intake of water and nutrients are likewise powered by nitrogen. Non-flowering plants are the target group for high-N fertilizers.
Because it starts converting starches and carbohydrates into food while utilizing stored energy, phosphorus is essential to photosynthesis.
Additionally, it encourages flowering plants to produce buds and strong root systems. The same proteins and enzymes that nitrogen utilized to control water and nutrients are also formed at the same time.
Potassium helps plants transport water, minerals, and food produced by photosynthesis. It also activates the proteins and enzymes that phosphorus and nitrogen were used to build, supporting a healthier field.
Potassium helps plants conserve moisture, which boosts their tolerance to environmental stress and disease. Additionally, it works particularly well to increase a lawn&#;s ability to withstand cold winters when dormant.
When used properly, urea can significantly increase the amount of nitrogen available in the soil and quickly revitalize worn-out fields. However, there are some drawbacks to have in mind before employing it. Read along to see the benefits and disadvantages of excessive use of 46-0-0 fertilizers.
Enhances the absorption of water
Provides an instant green by dissolving leaves into easily identifiable forms to produce beneficial nutrients for your grass.
Increases nitrogen availability in soil.
Pocket friendly.
Biuret, a typical contaminant found in synthetic urea, actually hinders plant growth.
Some organic substances, including limestone, don&#;t mix well with urea (organic phosphorus).
The shelf life of urea is quite brief.
When it is applied to the soil, the catalytic action of urease causes urea fertilizer to interact with water (hydrolyze) to create ammonium carbonate [(NH4)2CO3].
The urease enzyme is a byproduct of the microbial breakdown of organic matter and is found in soil.
An unstable compound, ammonium carbonate, is formed for a short time. It breaks down into the water, carbon dioxide, and gaseous ammonia (NH3).
When it is added to the soil, NH3 is transformed into ammonium (NH4+) by hydrogen ions (H+) from soil particles.
The positively charged ammonium ions are then incorporated into the negatively charged soil particles, where they stay until they are either taken up by plants through the roots or used as an energy source by bacteria to nitrify (convert to nitrate, NO3-) in the process of nitrification.
How To Apply
This Fertilizer can be used dry, in granular form, or mixed with water in liquid form, before growing any plants, till the soil to apply a 46-0-0 fertilizer for effective application.
Urea can be added to the soil as hard grains, prills, or lentils.
The white, crystal granule formulation has the most promise.
By adding a water-soluble form to your irrigation water, you could also introduce it to the soil.
When applying granules, a quarter-inch of rain is sufficient to mix the urea deeply enough into the soil to prevent ammonia loss, which is advantageous to plants.
For your better understanding of how to use 46 0 0 fertilizer, more details are provided below.
Apply urea on chilly days to lessen ammonia damage. It is ideal for applying urea on chilly, windless days when the temperature is between 32 and 60 degrees Fahrenheit (0 and 15.6 °C).
Urea dissolves on the lawn when the soil freezes at lower temperatures. At warmer temperatures and humidity, urea decomposes more quickly than it can become wet in the ground.
The enzyme urease starts the chemical process that turns urea into nitrate plants. Before your plant benefits from the high amount of urea, you can reduce it by applying this Fertilizer before planting.
Chemical reactions can be slowed down, and urea can be kept in the soil using fertilizers with urea inhibitors.
Small, hard pills or urea particles are packed and offered for sale. Applying another fertilizer first can disperse urea uniformly across your landscape. For most trees, you should maintain this Fertilizer close to the tree&#;s roots or the area where you will sow the seeds.
Urea first decomposes into ammonia gas and then nitrate. Applying Fertilizer as soon as the soil becomes wet will help the fertilizer dissolve in the soil before the chemical reaction begins since the gasses can easily escape from the soil surface.
As a result, more ammonia is trapped in the soil. To retain the ammonia gas as much as possible in the soil, the top 1.3 millimeters of the surface should be moist. You can water your grass by yourself, spread urea on your property after 48 hours of the snow melting, or spread it there before it rains.
An excellent strategy to spread this Fertilizer before your ammonia gas is harmed includes harrowing, dragging, or shrinking your field so that urea can stay in the top layer of soil.
Most cereal grains can be immediately treated with urea, but not always at temperatures above 60 degrees Fahrenheit. When employed in warm environments, the plants emit an ammonia-like odor.
Due to the 46-0-0 NPK&#;s adaptability in use, farmers, gardeners, and homeowners with lawns all utilize it. However, because it only provides nitrogen, plants that need phosphorus, potassium, and other essential minerals should receive supplements.
Remember that ammonia-rich fertilizers shouldn&#;t be used for longer than six months because they can alter the composition of your soil over time!!
Because different plants have varying needs if you need to reapply any compound fertilizer during the season, ensure it doesn&#;t always contain just one ingredient, such as an N-P-K mix or organic material alone.
It is strongly advised to use a 46-0-0 NPK fertilizer on your lawn only after a soil test has revealed a nitrogen deficiency. It should be used once a year, in April, just before new growth starts.
Root burn and crispy, brown grass could happen when such high amounts are treated in areas with enough nitrogen already present. Apply this Fertilizer only to grass that is actively growing and only until a second soil test indicates that the nitrogen content has improved.
As for the application, remember to spread one pound of Fertilizer over a surface area of 1,000 square feet.
Ornamental grasses are quite common due to their reputation for being low-maintenance and their tendency to thrive in unfavorable soil. They are unlikely candidates for heavy nitrogen formulae since they naturally resist pests, diseases, and environmental challenges.
In general, these grass varieties don&#;t need to be fertilized frequently, and they frequently give gardens year-round appeal. However, when planted with other ornamentals in nutrient-deficient soil, a significantly diluted amount of this Fertilizer may aid in root establishment.
Corn plants require more nitrogen to support their thick stalks and huge leaves that protect tightly packed cobs. Nitrogen is a crucial macro- and micronutrient that corn requires to generate delicious, well-formed grains.
A sprinkle of polymer-coated 46-0-0 granules can improve nitrogen access for healthier plants if your corn&#;s leaves turn brown out of season or the cobs are tiny and lacking kernels. Remember, direct contact with urea harms the seeds and often lowers maize plant yields.
Developing well-formed, bright foliage and florets depends more on nitrogen in leafy crops like lettuce, broccoli, and cabbage because they rarely bloom. Remember to apply four ounces (12 cups) of Fertilizer every 30 feet of row in vegetable gardens.
An initial application of 46-0-0 Fertilizer will encourage strong roots, rich color, and greater size when nitrogen is deficient in the soil.
Liquid solutions should be used in the morning or late at night to prevent leaf burn. The same effect is achieved by dispersing granules three inches apart from each plant.
Houseplants are confined to containers and are extremely sensitive to fertilizer levels. Only a heavily diluted quantity of 46-0-0 Fertilizer would be suitable, even with the extra runoff common with houseplants, but only for non-flowering plants.
When used correctly, and when recycled potting soil is routinely used, this technique can be highly effective. Potting soil will gradually lose its natural nutritional qualities. Utilizing 46-0-0 Fertilizers sparingly can aid in partial fertility restoration.
Given their size when fully grown, trees and shrubs are frequently the plants that consume the most nitrogen. This nutrient causes the largest growth response. However, early in the spring, when fruit trees and berry bushes are just beginning to sprout, farmers use this Fertilizer.
Trees can be treated with liquid urea at two diluted ounces each month while growing in a flat location. Slow-release granules will provide the safest form of nitrogen infusion on slopes or regions where the possibility of runoff is higher.
Some potato types may withstand high nitrogen concentrations; some cannot! Take care and handle all plants the same. Avoid providing high amounts of nitrogen to potato plants when using this Fertilizer.
46-0-0 Fertilizer can be sprayed on potato plants directly or mixed with other fertilizers to a solution that contains no more than 30 percent nitrogen. Remember that only before planting potatoes should you fertilize the soil with fertilizer solutions that contain more than 30 percent nitrogen.
There are four fertilizers, each with various applications and gardening techniques.
46-0-0 liquid Fertilizer is applied around your plants after being diluted with water. Some such fertilizers have foliar spray formulations as well. The soil or leaves then rapidly transport nutrients to the root system.
Despite their tendency to momentarily raise soil pH, liquid urea feeds are very cost-effective. It is advised to exercise caution, though, as overfeeding is common and can result in the root, flower, and foliage burning.
Options for powdered urea can be mixed with water to make a &#;tea&#; or worked straight into the soil towards the base of shrubs and plants. They have a limited shelf life but store well in an airtight container.
Powders are among the most affordable; however, they might work better in larger applications like farms or coppices. In smaller gardens, these could be too much to handle if precise measurements are not taken.
Granules are highly concentrated, convenient to use, and offer ongoing nutrition for up to nine months. In only a few weeks, the initial findings will become apparent. Furthermore, they are less prone to result in root burn.
Casting granular fertilizers uniformly around the base of trees, shrubs, and other plants is how you apply them. They do not require watering to become active and are less prone to contaminate adjacent surfaces or groundwater.
Especially if you have a container garden, spikes are one of the easiest to employ. They are simple to put into loamy soil because they are pre-measured in various sizes. They also have a reduced danger of burning because of their delayed release.
Microbes that naturally exist in the soil release nutrients from the spikes. And have the additional advantage of promoting a higher resistance to disease and pests. The leftovers can then be kept clean until needed.

Urea or Nitrogen 46% is an organic crystalline solid with a low melting point. It is white and odorless which is highly soluble in water. Urea is derived mainly from natural gas and petroleum feedstocks, making it a petrochemical product.
Urea is not acidic or alkaline. Its density is 1.32 g/cm³ at room temperature.
Urea fertilizer is widely used in agriculture. It contains large amounts of Nitrogen, which is essential for plants.
Urea formula is CO(NH2)2 that you can see its chemical structure in the below:
If you are interested in knowing more about urea, read this article.
Urea was first synthesized in a laboratory by the German chemist Friedrich Wöhler in .
He prepared urea as an organic material from ammonium cyanate as a mineral substance.
The basic process of urea production was named Bosch-Meiser in .
In the industry, urea is prepared from the combination of ammonia and carbon dioxide at high pressure and high temperature.
Currently, there are different methods for producing urea.
There are various methods to produce urea. Below, the two methods of urea production are explained:
First ammonia and carbon dioxide react under high temperature and high pressure, then ammonium carbamate is formed, then it decomposes into urea and water.
In this process, Nitrogen and Hydrogen gasses react under high pressure and high temperature in the presence of an iron catalyst, then ammonia synthesis. Finally urea is produced through a process called the Bosch-Meiser urea process.
This is the most important method to produce urea, because Nitrogen in the atmosphere is used in this method.
First, ammonia and carbon dioxide react together to produce ammonium carbonate. Then urea and water are formed from it.
There are several methods to concentrating the urea solution such as vacuum concentration, evaporation, and crystallization. In this stage, melted urea turns into solid urea.
Then in the solid formation stage, two models of solid urea such as granular and prilled are made.
To produce granular urea, the molten urea is placed on the plate and cooled. Then, it is produced by crushing the compound into particles with a diameter ranging from 1 to 4 mm. This form of urea has gained popularity in agriculture due to its ability to resist moisture and its suitability for various applications in this field. To know more about granular urea physical characteristics, you can check the urea 46 specification.
But to produce prilled urea, drops of molten urea are sprayed from the prill tower. Prilled urea is smaller than granular urea, making it easier to handle, transport, and use. It is used to produce plastics, resins, and adhesives. The diameter of prilled urea can range from 0.85 to 2.8 mm.
Next is the screening stage. In this step, the particles are screened with the appropriate size. Some of the urea is prepared for packaging and some will be loaded as bulk.
If you require more information about prill and granular urea, check the page Urea Type.
The table below provides the specifications for urea:
Urea fertilizer is one of the most important Nitrogen-containing fertilizers in the world that can be used in the agriculture industry.
Nitrogen plays a significant role in plant growth. It is one of the essential substances in farming.
It is necessary for the production of chlorophyll and amino acids. The lack of nitrogen in the soil will limit the plant growth.
Urea-formaldehyde resin is used in the production of multi-layered plastic products such as kitchen tables and adhesives.
This material is formed from the reaction of urea and formaldehyde, which has high strength, stability, and durability.
Urea or Nitrogen 46% is used as a raw material for the production of urea-based diesel exhaust fluid (DEF). This fuel additive is used in diesel engines to reduce harmful emissions of Nitrogen Oxides (NOx).
Urea can be used in soaps and washing powders as a softening and conditioning agent for the skin and fabrics. In soap production, urea can help to increase the lather and make the soap softer and more moisturizing.
Urea can also be used as a plasticizer in adhesive formulations to improve the adhesive&#;s flexibility and viscosity.
Other urea applications are coloring and industrial printing, teeth whitening, additives for a cigarette, flame-proofing agents, and so on.
Read Urea Applications article to know the urea uses in other industries.
The advantages of urea are as below:
Urea has a high Nitrogen content of 46%, which reduces expenses related to storage, transportation, and handling when compared to other dry Nitrogen forms.
Urea production does not release many pollutants into the environment.
When used correctly, urea&#;s efficiency is higher than other Nitrogen products such as potassium nitrate, calcium nitrate, etc.
Urea fertilizer is safe to use, as it does not pose a significant fire or explosion risk, making it a reliable fertilizer.
Despite the advantages of urea, this material also has disadvantages that we need to know about.
One of the disadvantages of urea is its volatility. It means that urea can easily evaporate in the atmosphere.
The volatility of urea can reduce the effectiveness of urea fertilizer performance.
Urea can react with soil and reduce soil pH by producing ammonium. This causes damage to the plant.
Urea is not considered a significant threat to aquatic life. If it is not used properly, it can contribute to water pollution. When used as a fertilizer, urea can transform into other chemicals that may end up in groundwater or surface water.
Urea fertilizer, it can release ammonia gas into the air. Ammonia gas can be harmful to human health and the environment. Using special forms of urea can help reduce the risk of ammonia emissions.
Urea is a corrosive substance, it can damage the skin and eyes. On the other hand, it can explode under certain conditions like high temperatures. So it should be handled carefully.
To store the urea, it is necessary to pay attention to the below cases:
If urea is exposed to moisture, it can absorb water and become lumpy, this condition is called caking. Lumps of urea can make it difficult to spread the fertilizer on the soil. At high temperatures, urea can decompose into ammonia gas.
Moisture and high temperature cause a decrease in urea efficiency in agriculture. so, this product should be kept in a dry and cool place.
Urea can react with some chemicals like nitrate, chlorine, and acidic materials. Its reaction can cause the release of toxic fumes, fire or explosions.
Urea should be stored in containers that are resistant to corrosion and leakage. Containers should be tightly closed to prevent moisture.
Protect the eyes, skin, and respiratory system. This includes safety glasses, gloves, and a respirator mask if necessary.
If it is hit during handling, it may spill and cause contamination.
The equipment should be clean and free of contaminants to prevent any chemical reactions or contamination.
It is important to follow all safety guidelines when handling urea to minimize any health effects.
It can irritate the eyes, nose, throat, and respiratory system if inhaled in high concentrations. Use appropriate respiratory protection when working with urea.
It can cause skin irritation, redness, and itching if it comes into contact with the skin. Wear appropriate protective clothing, including gloves and coveralls, when handling urea.
