Amifol K

Concentrated potassium fertiliser for high quality fruit finish with enhanced uptake due to anti-blocking agent.

Enhances fruit quality, weight and skin colour.
Increases yield while maintaining or increasing °Brix.
Formulated to have the highest absorption range of any Potassium (K) fertiliser.
Low Point of Deliquescence (POD) allows the Potassium to be absorbed at low humidity

Amifol K is a globally proven concentrated Potassium fertiliser that has low salt index and is free from nitrates and chlorides, minimising scorch risk.

Advanced Potassium Nutrition for Fruit Quality & Resilience

Amifol K is a globally proven, concentrated Potassium (K) fertiliser (38.6%) designed to support crop maturation, enhance fruit colour, and extend shelf life. Its innovative formulation—complexed with L-α Free Amino Acids—ensures superior uptake, even under challenging environmental conditions.

Key Features

  • High Potassium Concentration (38.6%)
    Delivers powerful nutrition in a low-volume, fully soluble liquid.
  • L-α Free Amino Acid Complex
    Boosts nutrient uptake and translocation for faster, more efficient results.
  • Superior Absorption at Low Humidity
    Formulated to absorb effectively at just 45% humidity—far lower than KNO₃ or K₂SO₄ (>90%).
  • Low Scorch Risk
    Salt index is 60% lower than KNO₃ and 75% lower than K₂SO₄, making it safe for sensitive crops.
  • Flexible Application Timing
    Use from fruit set to pre-harvest. Early applications promote fruit fill; later ones enhance colour and finish.
  • Crop Versatility
    Ideal for salad leaves, vegetables, bananas, and orchard crops. Suitable for all crops.
  • Application Compatibility
    Recommended for foliar spray and compatible with all fertigation and drip systems.
  • Certified Production
    Manufactured in ISO 9001 & ISO 14001 certified facilities for quality and sustainability assurance.
  • Convenient Packaging
    Available in 10 L format (other sizes available upon request).

– Recommended for foliar applications and also suitable for drip application.

Applications

Comment
Foliar General Dose 2 – 4 L / ha 2 – 5 Apply from fruit set onwards at times of    maximum fruit development or every 10 – 14 days
Vegetable Crops (e.g Carrot, Onion, Brassica) 3 4 – 5 Begin applications from 10 leaf stage in     Carrots and Celery or once foliage is sufficient in other vegetables. Apply every 10 – 14 days
Horticultural Crops (e.g Tomato, Capsicums & Melons) 2  – 3 3 – 5 Repeated applications during fruit set, swell and ripening. The gentle formulation of     Amifol K is safe for use on flowering on       extended flowing crops such as tomatoes and strawberries
Fruit Tress 2 – 5 3 – 5 Every 14 days from fruit set. Early applications favour fruit fill and late applications favour colour development
Turf

(Greens)

0.4 L / 100 m2 1 – 3 Use the higher rate where K deficiency is known. Irrigate off the leaf where possible after application. Repeat every 10 – 14 days
Turf

(Fairways, Sports)

20 – 50 L / 1000 L
Potato 3 3 – 4 Begin applications at row closure and

continue during early tuber formation

Grapes

(Table)

2 – 3 2 – 3 Apply during and after veraison especially in coloured varieties
Drip General Dose 8 – 12 3 – 5 Apply as required especially in vigorous

horticultural crops such as tomato and melon
