Foliar fertilizers, which are applied directly to the foliage of plants, are popular in both commercial and residential landscapes. Compost, lime, sulfur, and other soil amendments can help improve soil quality, but the urea fertilizer rate you use may not be enough to meet the plants’ nutritional needs in poor soils. For crops that are unable to absorb nitrogen from the soil because of high pH levels or other environmental factors, urea can be used in a foliar spray to supplement fertilizers.
How to mix Urea Fertilizer with Water can be simplified by determining the amount of water your garden needs. You can easily overlook something this straightforward. It’s not difficult, but it can be. That being said, you need to know how to do it like the back of your hand because urea fertilizer with water is likely to be used on your crops.
You should know how to mix urea with fertilizer before you even begin growing plants in a greenhouse because most crops benefit from nitrogen. As urea aids in photosynthesis, this is especially beneficial for leaf and flower growth. As a result, growing plants in an optimal setting like a greenhouse and learning about suitable fertilizer mixtures should result in a fruitful and potentially profitable harvest.
Urea Fertilizer: Advantages and Disadvantages
Fertilizers containing urea come in a wide range of nitrogen concentrations, from extremely high to extremely low. Fertilizers made from urea are commonly used as a fast-acting fertilizer, but it can also be combined with other ingredients to produce a long-acting fertilizer. Adding nitrogen to the soil with urea is a cost-effective method.
The quick solubility of urea in water is one of the urea fertilizer advantages and disadvantages. This makes it easy to incorporate into a fertilizer solution and foliar spray. The nitrogen in urea fertilizers needs to be soaked into the soil when they are administered as a liquid solution or as granules to prevent it from evaporating before the plants can absorb it. However, because nitrogen dissolves in water, it can wash away from the soil and end up in nearby waterways. For example, Frontiers for Young Minds points out that the decomposition of algae results in low oxygen levels and “dead zones” in both lakes and coastal waters.
Urea Fertilizer: How to Use
While plants utilize nitrogen to generate amino acids, too much nitrogen promotes stems and leaves at the expense of roots, flowers, and fruits, which are all essential for plant growth. Nitrogen deficiency slows the growth of plants. The right amount of nitrogen and other nutrients to apply depends on the needs of the plants and the makeup of the soil. Identify soil deficiencies and fertilizer needs by using a soil test kit or sending soil samples to a lab for analysis.
Aim for temperatures between 65 and 85 degrees Fahrenheit to apply foliar sprays, while the optimal time to do so would be between 9 and 6 a.m. According to University of Missouri Integrated Pest Management, a cool, gloomy morning is excellent since the humidity is higher and the leaves of the plants are able to absorb more of the urea solution.
The rate at which urea fertilizer is applied to soil varies depending on the plant and the time of year. There are two types of solutions: one that may be applied to the leaves, and one that can be applied to the roots, according to NMPRO Nursery Management & Production. Fertilizer solutions of 0.5 percent or 2 percent can be made with 1 heaping tablespoon of 46-0-0 urea fertilizer and 1 gallon of water. Pour the solution into the sprayer using a funnel, shake vigorously to dissolve the granules, and then lightly mist the leaves with the solution. Because too much urea can harm the plants, only a thin layer is needed.
Standard Safety Precautions
Before mixing and applying foliar sprays, wear protective clothing such as goggles, gloves, long sleeves, long pants, and closed-toed shoes. Even in dilution, fertilizer can cause skin burns and eye problems. When working with powders or granules, a dust mask is also a good idea. Do not allow children or pets to have access to any fertilizer or equipment used in the mixing or application of the fertilizer solution.
When applying any fertilizer either to the soil or as a foliar spray, avoid scattering the granules on hardscape or spraying more than your target plants. You risk washing granules down storm drains and into wetlands or waterways if you sweep them up and put them back on the landscaping or lawn. Excess foliar sprays can affect neighboring plants, so shield them with cardboard or cover them with plastic sheeting or tarps. After fertilizing, always water your plants quickly to allow granules and any remaining foliar spray solution to seep into the ground.
Things You Will Need

You risk washing granules down storm drains and into wetlands or waterways if you sweep them up and put them back on the landscaping or lawn. Excess foliar sprays can damage surrounding plants, so screen them with cardboard or cover them with plastic sheeting or tarps. After fertilizing, always water your plants quickly to allow granules and any remaining foliar spray solution to seep into the ground.
- Don’t spread granules on hardscape or over-spray your plants when using fertilizer in the soil or on the foliage. You risk washing granules down storm drains and into wetlands or waterways if you sweep them up and put them back on the landscaping or lawn. Use cardboard or plastic sheets or tarps to protect nearby plants from excessive foliar spraying. After fertilizing, always water your plants quickly to allow granules and any remaining foliar spray solution to seep into the soil.

How To Mix Urea Fertilizer With Water For Beginners
When urea fertilizer is mixed with water, correct measuring is the most important principle. As soon as you grasp it, there should be no trouble in making this mixture. To begin, you must first determine which urea fertilizer to use.
The urea fertilizer has a label that reads 46-0-0 for beginning gardeners. To put it simply, this indicator indicates that the bitrate is less than 0.25 percent. If the biurate grade of the urea fertilizer is too high, it can harm the plants.
Determine how much urea fertilizer you need to dissolve once you’ve chosen it. If you’re using foliar sprays to administer urea to your garden, you’re looking for a urea concentration of between 0.5 and 2% by weight. Urea should be mixed with water at the rate of 20 grams for one liter of water.
Put the powder in your sprayer and add water, and it should disperse easily with a moderate shake.
How To Prepare Liquid Fertilizer
The urea and water mixture explained earlier is an example of a liquid fertilizer. Spraying or saturating the soil with this fluid is one of the most prevalent methods of doing so. In this technique, you may rapidly and safely feed a diluted nitrogen solution to your plants.
You should use a 1% urea solution for leafy vegetables that benefit from liquid fertilizers. urea granules, weighing scale, water and a container with a marker are all you need to get started. Use the volume-to-weight equivalent of water, as explained earlier, to convert your volume to a unit of weight.
However, you can always simplify the use of liquid fertilizer if you like. Urea granules should always be added to the water supply, even in little amounts. Mark the top of a 1-liter bottle with this amount of water so you know how much solvent is left over.
What Is Foliar Spray?
A foliar spray is one that delivers nutrients to plants through the leaves themselves. Because they are absorbed directly by the leaves, vitamin shortages can be swiftly remedied. In addition to nitrogen, urea fertilizer mixed with water is a common foliar spray for other trace elements.
To begin, you can use urea fertilizer mixed with water at 0.5 percent urea, but you may need to increase it to 2 percent if your plants are deficient in certain nutrients. If the leaves on your plants are yellowing or rotting, it’s likely that they are deficient in nitrogen. You can then apply the solution to the leaves of your plants at night or in the early morning hours.
Light coating is acceptable as long as the entire plant is covered. Because absorption is less efficient while it’s hot, you should avoid spraying. In the next few weeks, your plants should be getting better, and this is when a greenhouse comes in handy.
There are a number of activities or occurrences that may have contributed to your plants’ troubles if nitrogen has been provided to them and you are confident in their indoor growing circumstances. On the other hand, if you’re growing your plants outside, there are a number of circumstances that could have contributed to the development of these symptoms.
Advantages And Disadvantages Of Urea
The first benefit of using urea as a plant fertilizer is its accessibility and affordability. You can store it for a long time because it is a convenient nitrogen supply and doesn’t require particular storage conditions. Urea is also used by some gardeners to make their soil more acidic.
However, if you don’t use urea correctly, there may be downsides. Using urea with less than 0.25 percent biurate is essential since it can be harmful to plants if the concentration is greater than this. Due of the loss of nitrogen when ammonium evaporates, people with big acreage may find urea impractical.
You should know how to make liquid fertilizer and foliar spray before you begin planting your garden. You can use a 46-0-0 urea fertilizer with less than 0.25 percent biurate to simplify the process of mixing urea fertilizer with water. The urea should be dissolved by weight or by remembering that 20 grams of urea per one liter of water is a good starting point.
