In order to flourish, plants must obtain the necessary nutrients from the soil using their root systems. Different types of fertilizers deliver primary nutrients, such as nitrogen, phosphorous, and potassium, as well as some of the essential secondary components that are required for plant growth.
The soil fertility decreases with each harvest and if the nutrients and other chemical compounds are not brought back up to their required levels, it can cause several deficiencies in the plants. Specifically, these NPK fertilizers come in different ratios of nitrogen, phosphorus, and potassium. For example, 10-20-10 fertilizer is a phosphorus fertilizer and has the right amount of Phosphorus present those chemical properties are best suited for a plant’s root system and likewise, you can see these fertilizers with different variations like 15-30-15, 5-10-5, 20-20-29, etc. So, you can choose the right one according to your plant needs. To know, which primary nutrient is required, you need to do the soil test.
Main Types of Fertilizers
But all fertilizers are categorized into 2 main types.
- Natural/ Organic Fertilizers
- Mineral/ Inorganic Fertilizers.
So, let’s discuss the basic categorization of fertilizers briefly.
Organic Fertilizers- The Natural ones

- Agricultural waste
- Industrial waste
- Livestock manure
- Municipal sludge
Inorganic Fertilizers – The Ones with Chemical Components
Main Types of Inorganic Fertilizers
Nitrogen fertilizers
The main types of nitrogen fertilizer you can in the market are:
- Ammonium Nitrogen Fertilizer: it also comes in different variations such as ammonium bicarbonate, ammonium chloride, and ammonium sulfate fertilizer.
- Nitrate nitrogen Fertilizer: this type of nitrogen fertilizer can be found as ammonium nitrate, sodium nitrate and calcium nitrate.
- Amide nitrogen Fertilizer
Nitrogen Inhibitors
Phosphorus fertilizers
- Water-soluble phosphorus fertilizer
- Mixed soluble phosphorus fertilizer
- Citrate-soluble phosphorus fertilizer
Potassium Fertilizers
- Potassium sulfate
- Muriate of potash
Other Mineral Fertilizers
· Calcium, Magnesium, and Sulphur Fertilizers
· Micronutrient fertilizers
· Inhibitor
different forms of Fertilizers to Consider When Approaching For npk Fertilizers
You can choose from a variety of types of garden fertilizers based on the delivery method and the amount of time that has passed since the last time the synthetic fertilizers were applied, depending on what kind of gardening approach and compound fertilizer requirements you have.
Water-Soluble Powdered Fertilizers
The term “water-soluble fertilizers” refers to types of fertilizer that are easily dissolved in water to make an aqueous solution and can be simply added to improve the soil fertility and add major nutrients such as. It is simple to exercise complete control over the proportion of each nutrient that is taken up by your plants when you use fertilizers that are water-soluble.

The fertilizer provides your plant with the right amount of supply nutrients and improves crop yields.
After repotting the plant with fresh potting soil, it will have the nutrients it needs for about a month before it needs to be fertilized again to keep growing at the same rate.
Fertilizers are widely available, and it should not be difficult to find one that is suited to the particular kind of plant you have.
In order to get the best possible results with your plants, you need to make sure that you follow the application instructions that are printed on the product label.
Your plants have the potential to achieve extraordinary results with the help of a consistent watering and fertilizer system, which in certain cases can aid in the growth of a plant that is developing slowly and sickly.
Using fertilizers that dissolve in water is the easiest way to make sure that the plants in your home, garden, or containers keep getting as many nutrients as they can.
This will lead to an increase in the quantity of growth that occurs. It is also the fertilizer that is the simplest to apply, whether you are a beginner or a skilled gardener, and as a result, it is the one that is used the most. So, give it a try with your plants and see the amazing results you can get by using water-soluble fertilizers the right way.
Despite being effective, water-soluble fertilizers are also prone to runoff.
Liquid Concentrate
A ready-to-use liquid concentrate fertilizer can be purchased, or the fertilizer can be purchased as a concentrate that needs to be diluted with water before it can be applied. Use a hose sprayer or a watering can to apply it directly to the garden soil.
This kind of fertilizer can quickly bring nutrients to both the roots and the leaves of plants, but it needs to be used regularly for its effects to last.
Liquid concentrate is an excellent fertilizer that can be used on indoor plants and in your home garden. Although it has a tendency to run off, in this situation the extra liquid is not absorbed and can seep out, either into the base of a plant pot or onto adjoining paths, surrounding plants, or – more critically – into local water sources. This can happen when a plant is not properly watered.
Slow-Release Granular Fertilizer
The term “slow-release fertilizer” refers to a type of fertilizer that gradually gives off a more significant dose of its nutrients as time passes. These may be natural and organic fertilizers that replenish the soil’s nutrient content through the process of their natural breakdown over time.
Slow-release fertilizer is usually coated with a plastic resin or sulfur-based polymers. These types of polymers cause the fertilizer to slowly decompose when exposed to water, heat, sunshine, or soil microbes- in short, it is a slow and controlled release process to increase crop yield by this phosphorus fertilizer efficiency.
Because they are controlled-release fertilizers, it may take a week before you can see any effects. However, because they work for four to three months, you don’t have to use them as often as you would with liquid concentrates.
The price of slow-acting fertilizer is typically a little bit higher per pound than the price of quick release inorganic fertilizer; however, because slow-release fertilizers need to be applied to the soil much less frequently, the total cost of both kinds of straight fertilizers over the course of a year is very comparable.
They may be applied quickly and easily, either manually or with a broad spreader to the soil surface for healthier crops or increased crop yield.

There are slow-release fertilizers available on the market, and they are used on many different kinds of plants, including shrubs, perennials, and trees. Each of the major fertilizer manufacturers, including Osmocote, Vigoro, Scotts Schultz, and Miracle-Gro, carries a line of slow-release fertilizers under their own brand names.
Fertilizer Spikes
The requirement to store and measure fertilizer is removed entirely when using fertilizer spikes. They just press into the wet soil, and as they break down, the nutrients they hold are released into the environment.
Larger species require more spikes, and as a result, they tend to be on the more expensive end of the spectrum when it comes to fertilizing. For this reason, they are best suited for usages in smaller areas, such as houseplants or small trees and plants in the yard.
The good news is that they can last anywhere from one to three months, and they do not produce any mess during that time. It is necessary to space them evenly apart and keep them away from the roots in order to prevent fertilizer burn.
Frequently asked Questions
What are the drawbacks of using excessive fertilizers?
Though, Fertilizer provide the soil and the plant with essential nutrients that help in plant growth. But excessive fertilizer can lead to severe problem in plants such as yellowing and browning of leaves. It may cause stunted growth of a plant. In more severe cases, the plant may burn. So, whenever you are using fertilizers, check the instructions on the package or consult an expert.
Conclusion
If you want to keep your plants or trees healthy, it is best to choose the right type of fertilizer according to your plant’s needs. Different NPK fertilizers are an efficient way to provide your garden, trees, shrubs, and potted plants the nutrition they need to thrive. This combination is suitable for use at any point during the progression of the plant because it may be applied to a wide variety of situations.
