Best Guide On How To Measure Fertilizer

You can learn how to measure fertilizer using various formulas and consider the application rate and nutrient content. Remember that more than the fertilizer concentration, the amount itself plays a significant role in the success of your garden. You have factors to consider to measure the fertilizer you’ll need; otherwise, it won’t be effective. 

The effects you want from fertilizing will be hard to achieve if you apply the amount blindly. More so, the New Mexico State University recommends testing your soil first to determine or create the ideal fertilizer for your plant or area. The combination of the right amount and content of fertilizer should get you the most of it.

How To Measure Fertilizer For Beginners


Get the square footage of your area and fertilizer recommendations

The Utah State University calculates the amount of fertilizer you’ll need based on your area’s square footage. What if it’s challenging to get the square footage of the location? The extension also provides the formulas you can use for various shapes of the landscape. 

Once you have the square footage, the next step is to get a soil test. This way, you can feel secured with the appropriate nutrient recommendations. Remember that these two factors are what you’ll use for the equation provided by the extension. The Oregon State University simplifies this formula by using the recommended quantities of fertilizer every 100 square feet. 

Once you have the numbers, remember that you also have to consider if you’re fertilizing a small garden, flower bed, or a large field. You will need to convert the amount to the appropriate measurement or use tools such as measuring cups, which are more suitable for smaller areas. More so, do not neglect to learn about fertilizer application rates and nutrient content


Measure the fertilizer application rate

As mentioned earlier, the first step before working with fertilizers is doing a soil test. Also, keep the major nutrient needs of your crops and plants in mind. In general, you can apply 0.1 to 0.2 pounds per 100 square feet of nitrogen, and the phosphorus and potassium content of the fertilizer depends on your soil to prevent problems with excess salt. 

Suppose you’re still confused with the formula explained earlier. The central concept is having the square feet and dividing the recommended amount of nutrients for your plants by the nutrient in the fertilizer. You can get the nutrient amount in your fertilizer by multiplying the bag’s weight by the percentage of each nutrient. 

You can always check the more detailed formulas of university extensions as well. 


Measure the fertilizer nutrient content

As you have previously read, the nutrient content is also an influential factor in measuring fertilizer. This isn’t a daunting task because you have all the information you need, and you’ll just need to compute them. For example, if you have a 50-pound bag of 10-10-10 fertilizer, you’ll only multiple 50 by each number. The NPK ratio is the succession of numbers, so the first one is the nitrogen, phosphorus, and potassium. 

You must calculate the nutrient content and amount of fertilizer before using it. These steps in measuring a fertilizer will prevent problems such as burnt roots and shoots. More so, you might not be solving any deficiencies if you are blindly applying fertilizer. 

To give you a general idea of these fertilizer nutrients, think of nitrogen as what you’ll need to encourage foliage growth. The next number in the NPK ratio, phosphorus, helps with rooting and flowering. Lastly, potassium helps with plant health and protection against diseases.

With this in mind, seeing a 10-5-5 fertilizer means it is high in nitrogen, and you’ll use it to encourage leafy growth. On the other hand, you can enhance your plants’ bloom with a 5-10-5 fertilizer since the second number has a high amount. 


How To Apply Fertilizer

There are many methods to apply fertilizer, and if you’re using a greenhouse, you might even find it more convenient to do maintenance practices like this. The consistent environment is also supportive of growth, and you can quickly check any potential problems once you saw signs in your plants. This way, you’re not overwhelmed with the possible causes. 

You can apply fertilizer by either broadcasting, banding, and side-dressing. Broadcasting is the most common application recommendation in fertilizers, so if you don’t see an application method, you can assume you’ll apply it by broadcasting. Broadcasting, from the name itself, is simply scattering fertilizer over the surface.

On the other hand, banding requires placing the fertilizer in a trench, and side-dressing is where you scatter fertilizer closely around the growing plants. With the latter method, be careful with the fertilizer touching the leaves to avoid burning. More so, some fertilizer will require incorporation onto the soil.  



The fertilizer will only be useful if you test your soil and learn your plants’ requirements. More so, you need to know how to measure fertilizer, whether it’s the amount you need to apply or the nutrient content suitable for your plants. In general, you can use different conversions and formulas recommended by universities to get the amount of fertilizer you need for your area. 

Being sure of the amount, rate, and content of the fertilizer will prevent potential burning and deficiencies. You’ll also get the most of the product by doing calculations before application.

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.
