Kelp Extract and other Key Ingredients

The benefits of Kelp and Humic Acid.

Kelp (Seaweed)

Every natural element known to man exists in the ocean. Kelp (seaweed) concentrates these elements in its tissues and provides plants with more than 70 minerals, vitamins and enzymes. Many scientific studies have determined what gardeners and farmers have known for centuries: Seaweed, or kelp, is one of the most valuable soil conditioners in the world. TerraLink’s granular kelp and kelp extract are derived from Ascophyllum nodosum, the most widely researched kelp in the world. Our kelp is harvested using sustainable practices from the pristine and productive waters off Nova Scotia and New Brunswick.

Benefits of added Kelp:

  • Improved plant health with natural bio-stimulants.
  • Increased plant resistance to environmental stresses such as drought and heat.
  • Increased pest and disease resistance.
  • Improved plants with bigger flowers and healthier, stronger leaves, stems and roots.
  • Better tasting fruits and vegetables.


Stabilized Nitrogen

Garden Pro fertilizers with stabilized nitrogen aren’t coated products and don’t rely on microbial degradation to release nitrogen. Stabilized nitrogen does not leach and is efficiently utilized by the plant. The result is that more of the nitrogen applied stays where it is intended for improved performance, value and environmental responsibility.

Benefits of Stabilized Nitrogen

  • Protects against nitrogen loss caused by leaching and volatilization.
  • Environmentally sound, providing consistent long term feeding and steady growth.


Humic Acid

Humic acid is a component of humus that is naturally present in soil organic matter. It is extremely important in increasing and maintaining soil fertility.

What does humic acid do?

Possessing an overall negative charge, it attracts positively charged nutrients such as calcium, magnesium, potassium and ammonium (to name a few). Humus which contains this acid becomes a bank which holds nutrients and releases them in response to plant or beneficial microorganism needs. Their molecules attract and bind with trace minerals that would otherwise be unavailable to the plant.

As plant roots grow through the soil in search of nutrients, they feed on humus. Each plant root is surrounded by a halo of positively charged hydrogen ions that are a by-product of respiration. The root actually ‘bargains’ with the humus, exchanging some hydrogen ions for positively charged nutrient ions attached to the humus.

Humus also attracts water molecules which improves the soil’s moisture holding capacity and provides carbon as a source of energy to beneficial soil microbes. This results in an active, healthy soil.
