Smarter Nitrogen Nutrition Starts Here: Discover Multiplex Liquid N

04 June 2025

Nitrogen is a key macronutrient in agriculture which forms the backbone of amino acids, proteins and chlorophyll. It is the driving element which is required for photosynthesis, metabolism and DNA/RNA synthesis that determine crop growth and yield. In soil, it is available to the plants in ionic forms of nitrate or ammonium—each with different mobility and availability---which affects how plants absorb it and how much is lost due to leaching or volatilization. Thoughtful management of these forms, through precise timing and application rates, maximizes plant vigor and biomass while minimizing environmental losses.

Role of Nitrogen in Plants

  • It boosts leaf growth by promoting the production of large, green leaves for better light absorption.
  • Helps in chlorophyll production, which is essential for photosynthesis and energy production.
  • Aids in plant metabolism, as it is involved in enzymes that support nutrient use and energy flow.
  • It helps in building proteins as Nitrogen is required for the formation of amino acids, which are the building blocks of proteins, enzymes and hormones.
  • It supports DNA & RNA formation as it is the key element for genetic material and cell division.
  • Increases yield by enhancing overall plant growth and productivity.
  • Nitrogen stimulates root growth and uptake of other nutrients.

Effects of Nitrogen Deficiency in Plants

  • Appearance of light green to pale-yellow color on the older leaves, starting from the tips.
  • The leaves and young fruits tend to drop prematurely.
  • The kernels of cereals and other seeds become smaller in size, loss of seed weight.
  • Root growth is severely affected, and tillering in cereal crops is greatly reduced.
  • This is followed by death or dropping of the older leaves, depending upon the degree of deficiency.
  • In acute deficiency, flowering is greatly reduced, and low protein content.

Different Forms of Nitrogen available for plant uptake are:

  • Nitrate (NO₃⁻): Highly mobile in well-aerated soils, absorbed via root transporters, then reduced to NH₄⁺ before amino acid synthesis; prone to leaching.
  • Ammonium (NH₄⁺): Binds to soil particles in acidic or anaerobic conditions, taken up directly and assimilated via the glutamine synthetase pathway; toxic at high levels.
  • Organic Nitrogen: Present in amino acids and proteins, generally mineralized by microbes into NO₃⁻ or NH₄⁺ before uptake, though some mycorrhizal plants absorb it directly.

Disadvantages of Using Traditional Nitrogen Fertilizers

Traditional nitrogen fertilizers, though widely used, come with several disadvantages when compared to advanced formulations like Multiplex Liquid N .

  • Amide fertilizers like urea provide high nitrogen concentrations but are prone to volatilization if not properly incorporated into the soil.
  • As urea is subsidized in India, it encourages its overuse, causing nutrient imbalance, soil degradation, threatening agro-ecosystem sustainability and also causing a fiscal burden for the nation.
  • Nitrate fertilizers such as sodium nitrate and calcium nitrate are highly soluble and prone to leaching, and their low nitrogen content requires higher application rates.
  • Ammonium fertilizers like ammonium sulfate and ammonium chloride has a risk of volatilization in alkaline soils and can cause toxicity in sensitive crops.
  • Anhydrous ammonia offers very high nitrogen content but requires specialized handling and poses significant safety hazards.
  • Ammonium-nitrate mixes such as ammonium nitrate and calcium ammonium nitrate, are effective yet carry explosion risks, contribute to nitrate leaching, and lack storage stability.
  • Calcium cyanamide releases nitrogen slowly and can damage seedlings if misapplied.
  • These traditional nitrogenous fertilizers have low nitrogen use efficiency and storage losses causing environmental pollution.

To overcome this issue, Multiplex has developed a unique nitrogen fertilizer, Multiplex Liquid-N – a reliable nitrogen source for your crops!

What is Multiplex Liquid N?

Multiplex Liquid-N is an FCO-approved, water-soluble nitrogen fertilizer suitable for use in all crops which has a carefully balanced composition of 16.5% Urea nitrogen, 7.5% Ammonical nitrogen, and 7.5% Nitrate nitrogen, with a total available nitrogen content of 32%. It ensures both an immediate and sustained nitrogen supply to plants.


How does Multiplex Liquid N work?

Multiplex Liquid-N has nitrogen in easily available and absorbable form which works through fine droplets that adhere to the leaf surface and penetrate the stomatal openings within minutes. It helps in faster assimilation of nitrogen in plants when applied on the foliage.

On application of Multiplex Liquid-N, the leaves absorbs inorganic and organic nitrogen sources through small pores within leaf cuticles. As these pores are lined with negatively charged molecules, uptake of cations like ammonium form of nitrogen is faster which are required for crops like paddy and maize for boosting yield.

Urea nitrogen, in the form of amide, is small, uncharged and highly soluble, allowing quick absorption through leaf pores. Once absorbed, it converts into ammonia and carbon dioxide with the help of the urease enzyme present in many plant leaves.

Whereas, Nitrate form of nitrogen are readily absorbed and utilized by most of the field crops in the early stages of their growth.

How to use Multiplex Liquid-N?

  • As a foliar application, mix 5 ml of Multiplex Liquid-N in one liter of water and spray during the vegetative stage.
  • For best results, apply twice. First spray at 15–20 days after germination/transplantation, and again 15–20 days later or before flowering.
  • For fertigation, apply 1 liter of Multiplex Liquid-N per acre.
  • For drenching, mix 5 ml of Multiplex Liquid-N in one liter of water and drench the plants thoroughly.

Benefits of using Multiplex Liquid-N

  • Multiplex Liquid-N has higher nitrogen use efficiency up to 80% by plants compared to traditional urea.
  • It provides fast-absorbing nitrogen forms for quicker plant growth response.
  • It accelerates nitrogen assimilation into proteins, boosting cell division and tissue development.
  • It is suitable for foliar spray, fertigation or soil drench across all growth stages and crops.
  • It helps to boost vigor with stronger stems, healthier roots and improves stress resilience.
  • Increases chlorophyll and stomatal efficiency for greener leaves and higher biomass production.
  • Promotes more tillers, branches, and fruit set while improving size, nutrition, and market value.
