FMC Petra Biosolution: Unlock Soil Potential with Reacted Carbon Technology

Stop soil nutrient lock-up. Start seeing explosive root growth.

FMC Petra is not just a fertilizer; it is a revolutionary soil amendment powered by Reacted Carbon Technology (RCT). In many soils, up to 90% of the Phosphorus you apply gets "fixed" (locked up) and becomes useless to the plant. Petra solves this.

By combining Phosphorus, Nitrogen, and Zinc with organic carbon at a molecular level, Petra prevents nutrients from getting tied up in the soil. The result? Your crops get the food they need to build massive root systems, resist stress, and deliver higher yields.

Why farmers choose itWhy Choose This Product? Key Benefits
  • ⏱️ Rapid Root Expansion: High-density Phosphorus stimulates immediate root development for better crop establishment.
  • ?️ Nutrient Shielding: RCT protects Phosphorus from reacting with soil metals, keeping it available for the plant roots.
  • ⏳ Sustained Release: Creates an "ebb and flow" of nutrients, ensuring plants are fed consistently over time.
  • ?️ Stress Tolerance: Helps crops survive in high-salinity (salty) soils and balances adverse pH conditions.
  • ? Bio-Stimulation: Feeds beneficial soil microbes, improving overall soil health and nutrient mineralization.

Product scienceHow It Works: Mode of Action

Standard fertilizers dump nutrients that quickly get "locked" by soil particles. Petra uses Complexation to solve this.

  1. Protection: The proprietary organic acids in Petra wrap around the Phosphate ions. This "shield" prevents the Phosphorus from reacting with Calcium or Iron in the soil.
  2. Site Competition: The carbon in Petra occupies the "locking sites" on soil particles, leaving the nutrients free floating in the soil solution.
  3. Microbial Activation: The carbon acts as a food source for soil bacteria. These bacteria release enzymes that further help the plant roots absorb food.

How to applyDosage & Application Guide

The Golden Rule: Always follow the "Dose per Acre" for accurate results.

How to applyDosage per Acre, Litre, & Pre-Harvest Interval (PHI)
CropDose (ml / Acre)Water (L / Acre)Dose (ml / Litre)PHI (Days)
Vegetables & Fruits2000 ml - 3000 mlDepends on method10 - 15 ml / L0
Sugarcane / Cotton2500 ml - 3000 mlDepends on method10 - 15 ml / L0
Field Crops1500 ml - 2000 mlDepends on method10 ml / L0

*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.

Useful detailsHow to Apply: Best Practices
  • Timing: Apply during early root development stages (transplanting) or before flowering for best results.
  • Mixing: Petra is compatible with most fertilizers, but always perform a jar test. It is best applied via Drip Irrigation or Soil Drenching.
  • Coverage: Ensure the solution reaches the root zone (rhizosphere) where roots can actively uptake the nutrients.
  • Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
