Product Description

Optimized Crop Strength – Ideal for Flowering & Stress Resistance

Fertisil 46.5 is a nano-particle-based liquid fertilizer formulated for high potassium and sulphur availability. It plays a vital role in enhancing crop vigor, improving drought resistance, and boosting flowering and fruit setting. The chlorine- and sodium-free formulation ensures sustainable soil health and prevents salinity issues.


Key Benefits & Advantages


  • Improved Flowering & Fruit Development – Potassium enhances flower retention and fruit setting.

  • Stronger Plant Immunity & Stress Tolerance – Sulphur strengthens enzymatic functions and disease resistance.

  • Better Nutrient Uptake & Transport – Potassium regulates water balance, enzyme activation, and photosynthesis efficiency.

  • Enhanced Oil & Protein Formation – Sulphur is essential for amino acid synthesis in oilseeds and pulses.

  • Drought & Heat Resistance – Potassium improves osmotic balance, reducing water loss and heat stress.

  • Optimized Sugar & Starch Accumulation – Supports grain filling and fruit quality in sugarcane, cereals, and vegetables.

  • 100% Water-Soluble for Quick Absorption – Ensures rapid uptake via fertigation and foliar application.

  • Sodium & Chlorine-Free for Long-Term Soil Health – Prevents soil degradation and salinity accumulation.

  • Recommended Applications


    Ideal Crops: Best suited for cereals, pulses, oilseeds, vegetables, sugarcane, fruit orchards, floriculture, and cash crops.


    Application Methods & Dosage:

  • Drip Irrigation: 1–2 Lit/acre for targeted nutrient delivery.

  • Foliar Spray: 2–3 ml/Lit of water for rapid potassium and sulphur uptake

  • Best Application Stages:

  • Early Vegetative Growth: Enhances root anchoring, shoot expansion, and stress resilience.

  • Pre-Flowering & Bud Formation: Ensures better reproductive growth and increased flower viability.

  • Fruit & Grain Maturation Stage: Improves seed filling, oil content, and overall yield quality.

  • Storage & Safety Guidelines


  • Store in a cool, dry environment, away from direct sunlight.

  • Use protective gloves and masks while handling concentrated solutions.

  • Compatible with most fertilizers and agrochemicals, except high-calcium solutions.
