NTS Fulvic Acid

NTS Fulvic Acid

NTS Fulvic Acid is a fulvic acid powder, 70 percent fulvic acid, made by Nutri-Tech Solutions. Fulvic acid is a chelator: it holds iron, zinc and other metals in solution so roots and leaves can take them up. It is a carrier for foliar sprays and drenches, not a fertiliser.

What it is

Fulvic acid is the smallest and most water soluble fraction of humic substances, the dark organic matter left when plant material breaks down. This powder is made by Nutri-Tech Solutions (NTS) and is sold as 70 percent fulvic acid.

What it does

• A chelator is a molecule that wraps around a metal ion, such as iron or zinc, and holds it in a soluble form, so the metal stays in solution instead of precipitating out of reach of the root.
• Growers use fulvic acid as a carrier: it goes into foliar sprays and drenches that contain trace elements, so the metals stay available on the leaf and in the root zone.
• In trials, humic substances have increased lateral roots and root hairs. Results vary with the source, the dose and the size of the molecules.

Analysis

Typical analysis (Nutri-Tech Solutions, dry basis):

• Fulvic acid: 70 percent
• Nitrogen (N): 3.9%
• Phosphorus as P₂O₅: 5.7% (2.5% elemental P)
• Potassium as K₂O: 0.12% (0.1% elemental K)
• Sulphur (S): 6.9%
• Magnesium (Mg): 1.8%
• Calcium (Ca): 1.0%

How to use

• Foliar spray: 3 to 16 teaspoons (9 to 48 g) per 10 L of water.
• Soil drench: 1.5 to 8 teaspoons (4.5 to 24 g) per 10 L of water.
• Start at the low end and watch the plants when you first add fulvic acid or change products.
• NTS advises that the rates of nutrients, supplements and other products may need to drop by 10 to 30% when they are used with fulvic acid.
• If leaves burn after you add fulvic acid, reduce the rates of the other products in the mix.
