What is the Role of NPK in Plants?

 Plants need specific nutrients for their growth. Otherwise, they fail to grow and reproduce naturally. The top three nutrients needed for plant growth are NPK, which means nitrogen, phosphorus and potassium. iffco dap bag is one of the common nano fertilizers used to address the deficiencies of nitrogen and phosphorus in crops. The IFFCO Nano Diammonium Phosphate fertilizer is the first choice of many farmers who own farmlands of cauliflowers, corn, peas, etc. Mentioned below is a brief understanding of the important role of nitrogen phosphorus and potassium in the growth of plants:

  1. Nitrogen

It is a major component of chlorophyll, which plants use sunlight energy to produce food from water and carbon dioxide. The process is known as photosynthesis. Nitrogen is the main component of amino acids, which are the building blocks of proteins without which plants wither and die. Nitrogen is a key component of an energy transfer compound called adenosine triphosphate, which allows cells to conserve and use the energy released in metabolism.



  1. Phosphorus

Phosphorus is one of the essential nutrients for plant growth. It helps in plant functions, which cannot be replaced by other nutrients. Enough supply of phosphorus is required for the optimum amount of growth and reproduction. Phosphorus is required for crop production in relatively large amounts. Phosphorus plays an important role in plant processes involving energy transfer.


  1. Potassium 

Potassium plays a major role in increasing root growth and improving drought resistance. It is associated with the movement of substances in plant tissues, which include water, nutrients and carbohydrates. It helps in plant enzyme activation, affecting starch, protein, and adenosine triphosphate (ATP) production. The production of adenosine triphosphate regulates the rate of photosynthesis. It maintains turgor and reduces water loss and wilting.


The absorption of these nutrients from fertilizers is not only essential for growth but also for imparting resistance and susceptibility to plant diseases. Other than nitrogen, phosphorus, and potassium, other micronutrients essential for plant growth are copper, manganese and zinc. They are helpful in photophosphorylation and synthesis of chlorophyll metabolism of carbohydrates and phosphorus, respectively.

4 Noteworthy Uses of DAP in Agriculture

Image
  Di-ammonium Phosphate, also known as DAP , is largely use d as fertilizer i n agriculture due to its high content of essential macronutrients like nitrogen and phosphorus. Nitrogen is one of the key components of chlorophyll, responsible for the green color of plants and the production of food to support their growth. On the other hand, phosphorus is a major nutrient for plants that is vital for cell division and the overall development of the plant. When DAP is properly utilized in farming, it can result in higher crop yield. Mentioned below are 4 noteworthy dap use in agriculture . Provides Nutrition to Crops As DAP contains high levels of nitrogen and phosphorus, it is best for soil that lacks essential nutrition. By feeding these macronutrients, DAP enhances the growth and development of the crop. This is because photosynthesis is encouraged in the crops, which is best for their overall health. Budget-Friendly Fertiliser DAP is a fertilizer that comes at budget-friendly rat

Why Do Plants Need Nitrogen

Image
  Nitrogen is one of the most important macronutrients for plant growth. It is a major component of amino acids that creates the building blocks of proteins and enzymes in plants. Plants receive nitrogen from the soil in the form of nitrates (the inorganic salts) or organic materials made by bacteria from atmospheric nitrogen. Lack of nitrogen can lead to weak or stunted plants that show yellowing (Chlorosis) in the older leaves due to insufficient chlorophyll production. The upcoming slides will talk about the top 3 reasons  why do plants need nitrogen . Strong DNA Nitrogen is a great way to create amino acids that help to make proteins required for constructing cells. Nitrogen is the key building block for DNA or nucleic acids, the essential genetic material that aids plant cells to grow and reproduce. A lack of receptive genes can destroy entire crops in case of a fungal infection.   Chlorophyll Production Nitrogen is a vital part of the production of the chlorophyll molecule, which

How Organic Fertilising is a Boon to Your Plant Health

Image
  Fertilizers  provide nutrients to plants, essential for several reasons, including healthy microbe development, boosting crop yield, and improving soil fertility. However, compared to years of chemical applications and inorganic farming practices, modern growers have now become more conscious of what they are applying to their plants.  The art and practice of organic fertilizer application has gained immense popularity, and all for the right reasons. Let us delve into some key benefits of organic fertilizers, and why they are considered the secret recipe for abundant plant growth, yield and environmental health. Boost Plant Growth & Promote Healthier Roots One of the main reasons why farmers prefer using organic fertilizers is their ability to promote plant growth naturally and encourage a healthy root system. Roots are an essential channel house for plants. They are responsible not only for holding the plant to the soil but are a route for plants to utilize water, nutrients and
