How To Mix Urea Fertilizer With Water Correctly

One can simplify how to mix urea fertilizer with water by measuring what your garden needs. It’s relatively simple, but it’s also one of those tasks that you can mistakenly overlook. However, it’s a skill that you must know like the back of your hand, considering you are likely to use urea fertilizer with water on your crops. 

Before you even start growing plants in the greenhouse, you should already know how to mix urea with fertilizer because most crops benefit from nitrogen. In particular, this will promote leaf and bloom growth, and urea itself aids in photosynthesis. Therefore, one can conclude that if you grow plants in an ideal environment such as a greenhouse and learn proper fertilizer mixes, you should have a productive and potentially profitable yield without drawbacks. 

How To Mix Urea Fertilizer With Water Correctly

How To Mix Urea Fertilizer With Water For Beginners

It’s unnecessary to broaden the subject of mixing urea fertilizer with water because its main concept is proper measurement. Once you understand that, you shouldn’t have any problem with creating this mixture. But to start, you also have to know what urea fertilizer to work with. 

For newbie gardeners, you will find a label on the urea fertilizer indicating 46-0-0. To make the explanation simple, this label means that it has less than 0.25% of bitrate grade. You want to use a urea fertilizer with a low biurate grade because anything higher can injure plants.

Once you’ve selected your urea fertilizer, measure how much you want to dissolve. One of the most common ways to apply urea on gardens is by foliar sprays, and if this is the case, you’re aiming for around 0.5 or 2% urea by weight. In other words, 20 grams of urea per one liter of water is what you want for your mixture.

Once you have this measurement, put it in your sprayer and add the water, and it should dissolve easily with gentle shaking. 


How To Prepare Liquid Fertilizer

An example of a liquid fertilizer is the urea and water mixture previously discussed. This is one of the most common solutions to use for spray or drenching the soil. This way, you can quickly provide nitrogen to your plants in a dilute mixture that is safe for them. 

For leafy vegetables that usually benefit from liquid fertilizers, you want to have a 1% urea solution. Prepare urea granules, weighing scale, water, water dispenser, container, and a marker. Depending on the volume you need, convert it to a unit of weight using 1:1 volume-to-weight equivalent of water and follow the instructions discussed earlier. 

Technical accuracy is essential, but you can always simplify the usage of liquid fertilizer. In general, never forget to have 1 level tablespoon of urea granules in 1 liter of water. Put this volume of water in a 1-liter bottle so you can mark the top level that will indicate the solvent in excess for the water. 


What Is Foliar Spray?

Foliar spray refers to providing the nutrients via the leaves. Because the leaves directly absorb them, they can quickly remedy the plant of nutrient deficiencies. Urea fertilizer with water is a typical foliar spray for primary nutrients like nitrogen, but it is also useful for other trace elements. 

If you’re using urea fertilizer with water for foliar spray, you can use 0.5% urea to start, but it can be closer to 2% for nutrient deficiencies. Your plants will have discolored or decaying leaves, which indicates that they lack nitrogen. You can then spray the leaves of your plants with the solution at night or early morning.

You can do light coating as long as the whole plant gets covered. You mustn’t spray when it’s hot because absorption wouldn’t be as efficient. Your plants should get better in the next few weeks, and this is where using a greenhouse makes it easier to determine other potential problems.

If you have given your plants nitrogen and you’re sure that they have the optimal growing conditions indoors, you can quickly look for other practices or instances that may have caused plants’ problems. On the contrary, there will be many factors to consider that may have caused those signs in your plants if you’re growing them outdoors. 


Advantages And Disadvantages Of Urea

For starters, urea is easy to find, and it is affordable compared to other plant fertilizers. It’s a quick source of nitrogen, and it doesn’t have special requirements for storage, so you can keep it long-term. Some gardeners also use urea to acidify their soil

However, you should be aware that there can be drawbacks if you don’t use urea properly. Emphasis is necessary on using urea with less than 0.25% biurate because higher than this can be phytotoxic to plants. Additionally, those with large areas may find it impractical to use urea due to nitrogen loss when ammonium evaporates. 



Knowing how to prepare liquid fertilizer and foliar spray is a skill you should be ready to start planting. This includes how to mix urea fertilizer with water that you can simplify into using a 46-0-0 urea fertilizer with less than 0.25% of biurate. Measure how much you need to dissolve by weight or remember using 20 grams of urea per one liter of water and gently shake the container for the urea to dissolve fully.

How To Prevent Root Rot In Hydroponics: 3 Useful Tips

If you’re a newbie gardener who’s looking to find ways to hone your skills, you’d want to learn how to prevent root rot in hydroponics even before this problem affects your plants.

Hydroponics can be advantageous to crops in more ways than one. However, it also comes with risks of diseases, such as root rot, which can be destructive or even lethal to your plants.

Unfortunately, there are no effective methods to recover the wilted parts that were affected by the root rot once it hits your plants. The only thing you can do if you do not want this catastrophe to befall your crops is to prevent it before it happens. Read on to learn more about this subject.


What is Root Rot?

Root rot is a disease that attacks the plant roots and causes them to suffer decay. This usually happens when a lack of oxygen supply occurs in the substrate.

To give you an idea, think about plant roots that are submerged in water that only has a little oxygen in it. Over time, the plant suffocates and dies.

Aside from rot and decay, this disease also leads to the proliferation of fungi that are naturally present in the soil. These include Rhizoctonia, Alternaria, Pythium, Botrytis, Fusarium, or Phytophthora. As soon as fungi colonies start to grow, they tend to target the weakened roots and infect your precious plant babies.

Once the plant becomes infected, they won’t be able to take in what they need to grow – water, oxygen, and other nutrients. When this happens, it won’t be long before the plant dies.


What is Hydroponics?

In case you’re not aware, the term hydroponic is derived from a Latin word that means “working water”. To put it simply, hydroponics is an art that involves growing various types of plants without soil. If you’re like most people, the first thing that comes to mind when somebody talks about hydroponics would be a picture of plants with roots suspended into the water without using any type of growing medium.


Avoiding Root Rot in Hydroponic Systems

Detecting and identifying root rot can be tricky. When your plants get infected, their leaves and roots gradually wither until the whole crop itself dies from the lack of nutrients, which is a common symptom of many diseases.


What causes root rot in hydroponics?

One of the requirements in hydroponics systems is oxygen. Without it, your plants are basically on the road to death. On the other hand, lack of such is one of the major triggers for root rot, and it must be avoided at all costs.

Just like when planting in soil, you loosen up the ground so that your plants’ roots can have their required intake of oxygen. That is the case for crops grown in aqueous solutions as well. If they cannot breathe, they would not be able to grow.

Another agent for root rot is the temperature. The last thing you would want in your system are parasites that leech nutrients intended for your plants and infect the water during the process. In common terms, these fungi are called molds.

One of the best breeding grounds for these is warm and moist areas. For this reason, if the water temperature inside your reservoir is high, then you are susceptible to it. Something as minor as letting the solutions exposed to sunlight can already be a risk factor.


3 Useful Tips on How to prevent root rot in hydroponics

There is good news! Root rot in hydroponics can be prevented! Just follow these tips:

Tip#1: Use the right air pump

If you do not want root rot to affect your plants, you merely have to avoid its causes. If you need oxygen, keep the water bubbling by providing an air pump of appropriate size, and also give importance to proper ventilation in the room.


Tip #2: Maintain the temperature

The temperature should be maintained within the 70 to 80 degrees F range. Get rid of any materials that can make your system vulnerable to infections, and make sure not to disturb your crops while they are trying to grow.


Tip #3: Get rid of the rotten parts

However, if you failed in preventing the disease, then the rotten parts should be removed immediately. Cut them off as there is no chance of reviving them, and focus on the potential new growth instead. Fix your hydroponics system and eliminate the risks.


Why Give Greenhouse Gardening a Try?

Greenhouse gardening offers numerous benefits to greens aficionados who dare to take their gardening experience to the next level. Aside from acting as a shield against the effects of inclement weather, a mini, hobby, or semi-pro greenhouse can also serve as a protective layer that keeps harmful bugs and critters at bay.

What’s more, its enclosed structure allows you to control your plants’ growing conditions including the temperature, light, moisture, and ventilation of the greenhouse’s internal environment. With a controlled environment, you’ll be able to extend growing seasons and grow plants that aren’t native to your area.



No matter how well-informed you are about how to prevent root rot in hydroponics, you cannot completely eradicate the risks. Therefore, to avoid the worst-case scenario, you should be prepared to sacrifice the infected for the sake of others. While you’re at it, consider trying your hand at greenhouse gardening as well.
