Product Description

The Missing Link for Healthy Soil & Thriving Plants

A cost-effective, premium fulvic acid formula trusted by hydroponic and professional growers across Victoria, Queensland, and NSW.

Fulvic acid is a natural, powerful nutrient booster that delivers immediate nourishment to both plants and the essential microbes in your soil. It promotes strong root growth, unlocks vital nutrients locked in the soil, and helps plants resist disease and stress, making it one of the most valuable inputs for creating balanced, fertile soil and vigorous plants.

Why use Fulvic Acid

 

  • Boost nutrient absorption for healthier, faster-growing plants
  • Control root rot diseases like Pythium under certain conditions
  • Increase uptake of foliar fertilisers, herbicides, and pesticides
  • Stimulate root development and improve access to soil nutrients
  • Improve soil moisture retention and water use efficiency
  • Detoxify harmful soil pollutants, including heavy metals and chemical residues
  • Stabilise nitrogen fertilisers like urea for longer-lasting effects
  • Strengthen plant immunity and increase yield potential

Where to use Fulvic Acid: 

Lawns (Buffalo, Couch, Kikuyu & More)

  • Enhance grass root growth and nutrient absorption
  • Promote lush, green, drought-resistant lawns
  • Improve recovery from stress, wear, and disease
  • Compatible with popular grass types like buffalo, kikuyu, and couch

Gardens (Veggies, Flowers, Trees, Pots)

  • Boost nutrient uptake in garden beds, pots, and lawns
  • Improve seed germination and root development
  • Support soil microbes that break down organic matter
  • Help plants resist stress and disease by improving nutrient availability

Farms & Larger Properties

  • Chelate soil minerals, making nutrients more accessible
  • Detoxify soil from pesticide, herbicide, and heavy metal residues
  • Stabilise nitrogen fertilisers like urea for longer-lasting effects
  • Improve soil fertility in areas with low organic carbon
  • Compatible with acidic or alkaline soils and a wide range of fertilisers

Fulvic acid is compatible with most liquid fertilisers, soil conditioners, and foliar sprays, making it a versatile addition to your plant nutrition program. It works best when used as part of a balanced feeding routine to enhance nutrient availability and overall plant health. This product is suitable for a wide range of growing systems, including hydroponics, soil-based gardens, and broadacre agricultural applications. To ensure optimal results and avoid any compatibility issues, always perform a small trial when introducing fulvic acid alongside new products or application methods.

The Science Behind Fulvic Acid

Fulvic acid is a naturally occurring organic acid formed from the decomposition of plant and microbial matter. Its unique small molecular structure allows it to:

  • Act as a powerful chelating agent, dissolving minerals and trace elements so plants can readily absorb them
  • Rapidly enter plant membranes (often within 4 hours), delivering nutrients efficiently
  • Enhance photosynthesis by increasing stomatal opening, especially helpful in cloudy or low-light conditions
  • Promote beneficial soil microbial activity, improving nutrient cycling and soil health
  • Detoxify soils by binding to pollutants like pesticides, herbicides, and heavy metals, reducing their toxicity
  • Stabilise urea and other nitrogen fertilisers when applied to soil, reducing nutrient losses
  • Stimulate root growth, cell elongation, and division, contributing to stronger, healthier plants

Often called the ‘missing link’ in plant nutrition, fulvic acid supports soil and plant systems in ways that other fertilisers cannot.

Only have great things to say about Plant Doctor. Organic products and a competitive price, fast shipping and easy to contact with questions. Have had great results with the special mix for lawns, and my plants (indoor and outdoor) love the seaweed secrets. I am excited to test out some of the animal products soon!
