An Outlook on Binary Fertilizers: Types and Roles in Agriculture

Explore the key benefits and roles of binary fertilizers in agriculture, enhancing crop yield and soil health with essential nutrient combinations NP, NK, and PK.

Table of Contents

Binary fertilizers use a combination of essential plant macronutrients. These nutrients provide the energy and growth boost to the plants. These fertilizers are useful and usually present in equal and balanced amounts of nutrients. Three types of binary fertilizers, NP, NK, and PK, are useful and directly improve the plant’s productivity. 

In this article, I will share the complete information, the benefits of Binary fertilizers in agriculture, and the improvements of agricultural soil. I will share the most useful binary fertilizer types with their growth impact on the plants. 

What are Binary Fertilizers?

What are Binary Fertilizers

The term binary itself describes the addition and use of 2 different major nutrient-based fertilizers together to form a binary fertilizer. These fertilizers are used according to the plant requirements and soil tests. Through the use of binary fertilizers, the plant’s need for nutrient supplements can be increased. These fertilizers directly promote the growth of the plant parts and improve the rate of agricultural productivity. 

Types of Binary Fertilizers 

Certain fertilizers are used together to form a particular fertilizer for plants. The most common types of the Binary fertilizers are as follows:

  1. NP 
  2. NK
  3. PK

Elaboration of the Types of Binary Fertilizers with Benefits

1. Nitrogen and Phosphorus (NP) Fertilizers

These fertilizers provide a balanced combination of nitrogen and phosphorus to the plants. It’s readily available to the plants and absorbed quickly. This fertilizer is in the granular form and has the same quantities of nitrogen and phosphorus. Agricultural soil requires high Quantities of nitrogen for productivity. 

Benefits of NP Fertilizers for Plants

It provides the right proportion of nitrogen and phosphorus to the plants. These binary fertilizers are useful for performing various important functions in the plant body. Some of the most prominent benefits of the NP fertilizers are as follows:

  • These are important for making the plants healthy and nutritious.
  • Genetically, these are important to build up the structure of the nucleus in the plants. 
  • These binary fertilizers are important light-capturing molecules that stimulate the process of photosynthesis
  • It optimizes the Overall plant productivity. The plants show an effective and healthy growth pattern after using it.
  • They are important structures for the manufacturing of amino acids and proteins.
  • It strengthens the plant roots, stems, stalk, and flowers. 
  • It induces high-quality flower production in the plants. They also add to the nutritional value of fruits and vegetables.
  • They stimulate the working of the plant enzymes and promote the cell functions of photosynthesis and cellular respiration. 
  • Plants require nitrogen, which promotes the growth of the nodules in the plants. 
  • It improves the cell wall thickness and promotes the presence of ATP in the plant cells. 

2. Nitrogen and Potassium (NK) Fertilizers

Binary Fertilizers Nitrogen and Potassium NK Fertilizers

This binary fertilizer combines nitrogen and potassium in the right amount as plant nutrients. These play a key role in the plant’s genetic makeup, maintenance, and build-up. The application of these fertilizers is important and acts as a booster to continue the plant growth. It also increases the reproduction rate. Some of the most prominent benefits of NK fertilizers are as follows:

  • Nitrogen is the important building block for the formation of necessary plant proteins. 
  • They promote the plant’s productivity positively and prepare them with more nutrition. These are helpful for the plants and continue the process of plant development. 
  • NK produces important plant enzymes for metabolism.
  • It’s helpful to protect the plants against the drought conditions. 
  • Moreover, it stores the plant’s energy in the cells and prevents plant energy loss.
  • It produces grains that richly include the composition of starch content.
  • NK is vital for the sugars and starch translocations in the plant body. 
  • In addition to this, it prevents the plants from wilting and water loss.

3. Phosphorus and Potassium (PK) Fertilizers

Phosphorus and potassium are mixed up in these binary fertilizers to promote the right nutrition content to the plants. These are important in plant life to improve and promote plant growth. These are useful in NK form as they are utilized in an equal proportion. 

  • It provides resistance and improves the immunity of the plants against various diseases and pathogens.
  • It’s necessary to produce the proteins and amino acids. 
  • The presence of potassium helps transfer the food materials from one plant part to the other. 
  • These are essential for the plant’s reproduction and germination of seeds. 
  • It makes up the nucleotide composition in the DNA.
  • Besides this, they also promote the green color of the leaves and plants.
  • These are important for the flowering and fruitification of the plants.
  • With their addition, the plants become more drought-tolerant and resistant to environmental stress. 
  • It improves the water absorption process of plants from the soil. 
  • These are important for nitrogen fixation in the legumes.
  • They increase the plant stem length and are helpful for uniform crop maturity. 
  • Moreover, for seed formation, these are important elements.
  • Plant cell divisions are carried out by phosphorus in PK fertilizers. 

Impact and Benefits of Binary Fertilizers on Agricultural Soil

Impact and Benefits of Binary Fertilizers on Agricultural Soil

They add up the important plant nutrients within the soil. They enhance the plant’s productivity. It improves the process of seed germination. It builds up the strong water-holding capacity of the soil and improves the plant’s status. The process of nutrient uptake becomes easier using it. The plants growing with such nutrients in the soil effectively and quickly start to grow. It balances the amount of nutrients in the soil. These are essential elements that also improve the concentration of the other nutrients in the soil. 


Binary Fertilizers can be a great nutritious source for plants using essential plant nutrients. These growth promoters are used according to the plants and soil requirements. These fertilizers help perform many important roles within the plant body, such as the formation of the genetic systems, proteins, and cellulase structure formation. From seed growth to flowering and fruiting, they strongly positively impact plant growth and development. However, you have to proceed with caution regarding the utilized nutrient content in the plants.
