YaraMila Winner Fertilizer Composition

YaraMila Winner is a compound NPK fertilizer produced by Yara that contains a balanced mix of primary nutrients along with several secondary nutrients and micronutrients.

This complete fertilizer is specially formulated for high-value horticultural crops like fruits, vegetables, and potatoes.

Overview of YaraMila Winner

YaraMila Winner has an NPK grade of 15-9-20 along with added magnesium, sulfur, boron, manganese, and zinc. The inclusion of secondary nutrients and micronutrients makes it a multi-nutrient fertilizer tailored for intensive crop cultivation.

YaraMila Winner Fertilizer Composition

Some key features of YaraMila Winner:

  • NPK grade: 15-9-20
  • Nitrogen sources: Nitrate, Ammonium
  • Phosphorus source: Polyphosphates, Orthophosphates
  • Potassium sources: Potassium chloride, Potassium sulfate
  • Secondary nutrients: Magnesium, Sulfur
  • Micronutrients: Boron, Manganese, Zinc
  • Physical form: Prilled fertilizer

YaraMila Winner is specially designed to provide balanced crop nutrition across all growth stages for optimal yields and quality. The article examines the sources and roles of the major nutrients in this fertilizer.

Nitrogen Sources in YaraMila Winner

The total nitrogen content in YaraMila Winner is 15%. This nitrogen is supplied through a combination of nitrate and ammonium sources:

  • Nitrate nitrogen: Makes up 65% of the total nitrogen. Provides readily available nitrogen for rapid crop uptake and growth response.
  • Ammonium nitrogen: Makes up 35% of the total nitrogen. Provides a slower, more sustained release of nitrogen to the crop.

This balanced blend of nitrate and ammonium allows rapid greening and vegetative growth along with steady nitrogen supply during later growth stages. The non-acid forming nitrogen sources in this fertilizer help prevent soil acidification.

Phosphorus Sources

YaraMila Winner contains 9% phosphorus in a unique mix of polyphosphates and orthophosphates:

  • Polyphosphates: Make up 25% of the total phosphorus. Enhances root growth, nutrient uptake, flowering and fruit set.
  • Orthophosphates: Provide the remaining 75% phosphorus. Readily available for crop nutrition.

Polyphosphate use allows efficient phosphorus utilization while the orthophosphate ensures adequate phosphorus nutrition. This combination is tailored to stimulate early root and vegetative development while meeting needs during later growth.

Potassium Sources

The potassium content in YaraMila Winner is 20%, derived from:

  • Potassium chloride: 65% of the total potassium. Provides readily available potassium for early growth.
  • Potassium sulfate: 35% of the total potassium. Supplies sulfur besides potassium. Provides sustained potassium release.

This potassium blend promotes balanced crop development, improves stress tolerance and controls water regulation within plants. The chloride and sulfur also address secondary nutrient needs.

Secondary Nutrients

YaraMila Winner contains the secondary nutrients magnesium and sulfur:

  • Magnesium (MgO): 1.8%. Critical for chlorophyll synthesis and enzyme activation.
  • Sulfur (SO3): 9.5%. Necessary for optimum plant metabolism and nitrogen utilization.

These nutrients support various metabolic processes for healthy growth. They are often deficient in intensively cultivated soils.


The fertilizer contains small amounts of the following micronutrients:

  • Boron (B): 0.015%. Important for cell wall structure and fruit/seed development.
  • Manganese (Mn): 0.02%. Involved in photosynthesis, nitrogen metabolism and disease resistance.
  • Zinc (Zn): 0.02%. Required for enzyme activation, auxin synthesis and pollen formation.

Micronutrients serve vital physiological roles during all growth stages. Their addition prevents potential deficiencies in high-yielding crops.


YaraMila Winner provides a balanced mix of essential macro and micronutrients tailored for fruit, vegetable and potato nutrition needs.

The combination of nitrate and ammonium nitrogen, poly and orthophosphates, potassium chloride and sulfate supplies readily available as well as sustained release nutrition across crop growth cycles.

The added secondary nutrients and micronutrients prevent deficiencies and support optimal plant development.

This complete multi-nutrient compound is specially formulated by Yara for achieving high yields and premium quality in intensive horticultural production systems.
