Tundamix
Lignosulfonate-Complexed Sulfate Micronutrients

Overview

Tundamix® is a suspension of essential sulfate-based micronutrients complexed with lignosulfonate, a natural organic complexing agent derived from wood. It is designed to correct and prevent micronutrient deficiencies in all types of crops, while providing high foliar absorption and excellent compatibility in fertigation and hydroponic systems. :contentReference[oaicite:1]{index=1}

All components in Tundamix are accepted under USDA/NOP organic rules according to 205.601(j)(4) and 205.601(j)(6), though the product itself is not OMRI-certified. :contentReference[oaicite:2]{index=2}

What Is Lignosulfonate?

Lignosulfonate is an organic molecule that comes from wood — you can think of it like a “molecule of sawdust” that has been broken down into a form the plant can use.

Lignosulfonate carries negatively charged ions that bind to the positively charged metal micronutrients (Cu, Fe, Mn, Zn, Mo). When these charges join, they form a stable complex.

Why that matters:

  • It prevents micronutrients from binding to soil particles and becoming unavailable.
  • It protects the micronutrient long enough for the plant to absorb it efficiently.
  • Roots recognize lignosulfonate-complexed nutrients and favor their uptake.
  • It greatly improves foliar absorption by keeping the nutrient soluble on the leaf surface.

In simple terms: lignosulfonate keeps the micros free, soluble, protected, and ready for uptake.

Micronutrients in Tundamix & What They Do

Iron (Fe) – 2.5%

  • Prevents and corrects iron chlorosis (yellowing of new leaves).
  • Essential for chlorophyll production and strong photosynthesis.
  • Critical for energy transfer and respiration inside the plant.
  • Helps maintain vigorous new growth under cool or alkaline conditions.

Manganese (Mn) – 1.4%

  • Activates enzymes involved in photosynthesis.
  • Important for nitrogen metabolism and green leaf coloration.
  • Supports root system health and lignin synthesis.
  • Helps plants tolerate environmental stress.

Zinc (Zn) – 0.2%

  • Key element for root production and root elongation.
  • Essential for internode spacing and leaf expansion.
  • Critical for auxin (growth hormone) synthesis.
  • Improves flowering, fruit set, and overall crop vigor.

Copper (Cu) – 0.1%

  • Important for lignin formation and cell wall strength.
  • Involved in pollen formation and reproductive processes.
  • Enhances disease resistance in many crops.
  • Improves enzyme activity associated with photosynthesis.

Molybdenum (Mo) – 0.1%

  • Required for nitrogen conversion inside the plant (nitrate → amino acids).
  • Critical for legumes and nitrogen-fixing systems.
  • Supports flower formation and seed development.
  • Improves plant performance in acidic soils low in Mo.

Use Recommendations

Fertigation / Drip Irrigation

  • 3.5–6 L/ha as a preventive during vegetative growth.
  • Repeat every 20 days in cases of high deficiency until symptoms disappear.

Hydroponics

  • 6-8 ml per gallon during vegetative growth.
  • Repeat every 20 days for deficiency correction.

Foliar Application

  • 38 to 50 quarts per acre per application.
  • Every 7–10 days throughout the crop season when deficiencies are present.

Tundamix can be used in all crops: vegetables, orchards, fruit trees, ornamentals, flowers, nurseries, and turf. :contentReference[oaicite:4]{index=4}

Compatibility

  • Compatible with most fertilizers and agrochemicals.
  • Do not mix with very acidic solutions (pH < 3). :contentReference[oaicite:5]{index=5}
  • Always perform a jar test before complex tank mixes.

Why Growers Choose Tundamix

  • Fast correction of micronutrient deficiencies.
  • Excellent foliar uptake due to lignosulfonate complexing.
  • Organic-compliant ingredients under USDA/NOP rules.
  • Safe, broad-spectrum micronutrient coverage for any crop system.
  • Reliable in alkaline soils where micros often become unavailable.
