Comprehensive Guide to Nitrogen, Phosphate, and Potassium Fertilizers
Chemical fertilizers are characterized by high nutrient content and fast effects, but they also have some limitations, such as potential negative impacts on soil structure. This article will introduces nitrogen fertilizers, phosphorus fertilizers, and potassium fertilizers first.
Types Of Fertilizers: Everything You Need To Know
Discover the different types of fertilizers and how to choose the right one for your plants. Our comprehensive guide covers everything you need to know.
What Is NPK Fertilizer? Types of NPK Fertilizers
The letters "NPK" on a fertilizer label stand for nitrogen, phosphorus, and potassium, the three primary nutrients plants need to grow. The numbers on the label indicate the ratio (by percentage) of nitrogen, phosphorus, and potassium in the fertilizer container.

Nitrogen
There are basically two types of fertilizers namely inorganic and organic fertilizers. Inorganic fertilizers or chemical fertilizers are the ones that contains elements that support the growth of plants. For example: nitrogen, phosphorus, and potassium fertilizers. Now, we will see them one by one.
12 Low Nitrogen Fertilizers And When To Use Them
Today, we’ll be taking a look at some of the best low-nitrogen fertilizers, both organic and non-organic, and when you should use them in your garden.
High-nitrogen, low-potassium fertilizers are a specialized category of fertilizers characterized by higher nitrogen content and lower potassium content. These fertilizers are suitable for crops with high nitrogen requirements, such as legumes, root vegetables, and tubers. Below are some common types of high-nitrogen, low-potassium fertilizers:
-
Urea (NPK Compound Fertilizer): Urea is a nitrogen-rich fertilizer that typically contains a proportion of potassium and phosphorus. It can be used as a base fertilizer or topdressing fertilizer and is suitable for most crops.
-
Potassium Nitrate (NPK Compound Fertilizer): Potassium nitrate is a nitrogen-rich fertilizer that also contains a certain amount of potassium. It can be used as a base fertilizer or topdressing fertilizer and is suitable for most crops.
-
Potassium Sulfate (K₂SO₄): Potassium sulfate is a potassium-rich fertilizer that generally does not contain nitrogen. It can be used as a base fertilizer or topdressing fertilizer and is suitable for most crops.
-
Potassium Dihydrogen Phosphate (KH₂PO₄): Potassium dihydrogen phosphate is a potassium-rich fertilizer that also contains a certain amount of phosphorus. It can be used as a base fertilizer or topdressing fertilizer and is suitable for most crops.
-
Potassium Chloride (KCl): Potassium chloride is a potassium-rich fertilizer that generally does not contain nitrogen. It can be used as a base fertilizer or topdressing fertilizer and is suitable for most crops.
-
Ammonium Nitrate (NH₄NO₃): Ammonium nitrate is a nitrogen-rich fertilizer that also contains a certain amount of potassium. It can be used as a base fertilizer or topdressing fertilizer and is suitable for most crops.
-
Monoammonium Phosphate (NH₄H₂PO₄): Monoammonium phosphate is a nitrogen-rich fertilizer that also contains a certain amount of phosphorus. It can be used as a base fertilizer or topdressing fertilizer and is suitable for most crops.
-
Diammonium Phosphate ((NH₄)₂HPO₄): Diammonium phosphate is a nitrogen-rich fertilizer that also contains a certain amount of phosphorus. It can be used as a base fertilizer or topdressing fertilizer and is suitable for most crops.
-
Ammonium Chloride (NH₄Cl): Ammonium chloride is a nitrogen-rich fertilizer that generally does not contain potassium. It can be used as a base fertilizer or topdressing fertilizer and is suitable for most crops.
-
Calcium Nitrate (Ca(NO₃)₂): Calcium nitrate is a low-nitrogen fertilizer that contains a certain amount of potassium. It can be used as a base fertilizer or topdressing fertilizer and is suitable for crops with higher potassium requirements.
Key Considerations for Use:
-
Select Fertilizers Based on Crop Needs: Different crops have varying requirements for nitrogen, phosphorus, and potassium. Choose fertilizers according to the growth stage and nutritional needs of the crop.
-
Apply Fertilizers Rational: Pay attention to dosage and application methods to avoid over-fertilization, which can lead to soil salinization or nutrient waste.
-
Consider Soil Conditions: Fertilization effects vary depending on soil type. Conduct soil tests before application to understand the soil’s nutrient status and pH level, ensuring optimal fertilizer selection and use.
-
Account for Environmental Factors: Adjust fertilization strategies based on environmental conditions such as climate, weather, and pest/disease occurrences to ensure healthy crop growth.
