Crown BioGrow™

Product profile and technical sheet for Crown BioGrow™, the flagship biofertilizer formulation specifically designed for Agarwood (Aquilaria malaccensis)and other aromatic tree species under agroforestry systems.

Product Category: Solid Granular Biofertilizer
Manufacturer: Crown Organic Biofertilizers Inc. (COBI)
Tagline: “Feed the Soil, Grow the Tree — Naturally.”

1. Product Description

Crown BioGrow™ is a multi-strain biofertilizer that enhances root development, improves nutrient uptake, and rejuvenates soil fertility through biological nitrogen fixation and phosphate solubilization.

Formulated using eco-friendly carrier materials and fortified with beneficial microbial consortia, Crown BioGrow™ promotes healthy growth and higher survival rates of Aquilaria malaccensis, sandalwood, ylang-ylang, and other high-value forest and aromatic crops.

It’s a biologically active alternative to synthetic fertilizers — restoring soil health while providing a balanced nutrient supply over time.

4. Mode of Action

  1. Nitrogen Fixation – Atmospheric nitrogen is converted into forms usable by plants, reducing the need for urea or ammonium sulfate.
  2. Phosphate Solubilization – Microbes secrete organic acids that release phosphate from insoluble compounds in the soil.
  3. Rhizosphere Stimulation – Enhances microbial activity around the root zone for faster root establishment.
  4. Plant Growth Promotion – Produces natural plant hormones (IAA, GA, cytokinins) that stimulate growth.
  5. Biocontrol Activity – Suppresses soil-borne pathogens through antibiotic secretion and competition.
