IRON-6 combines iron, sulfur and Biofeed’s exclusive Amino-Cell Technology® ACT to increase leaf absorption and translocation of this important micro-nutrient. This combination promotes stronger plant growth, antioxidant production, enzyme activity for your lawn and soil and chlorophyll production resulting in darker green leaf color.

Sulfur (S)………………………………..3.0%
Iron (Fe)…………………………………6.0%

Derived from Ferrous Sulfate.

IRON-6 contains Biofeed’s exclusive Amino-Cell Technology® (ACT).



IRON-6 is highly concentrated for pro-level performance and value. Dilute with water prior to application to ensure adequate coverage. Jar test for compatibility prior to final tank mixing with other products. Not recommended for use in fertigation systems.

AGRICULTURE: Apply 2-6 ounces per acre with sprayer or through fertilizer injection system as directed by a qualified Biofeed Field Rep.

LAWNS & GRASSES: Foliar apply 1-2 gallons in 50-100 gallons of water per acre, or for smaller areas apply 4-8 ounces in 3-5 gallons of water per 1000 square feet. Apply every 7-10 days or as needed with sprayer. DO NOT IRRIGATE for 15-30 minutes following application to allow maximum foliar uptake.

FOLIAR FEEDING TREES & SHRUBS: Dilute 8-16 ounces in 100 gallons of water and spray on foliage to point of runoff. Repeat as needed.

ROOT FEEDING TREES & SHRUBS: Dilute 1-2 quarts to 100 gallons of water.


ACT® | L-Form Amino Acids, Carbon, Hydrogen, Oxygen and Nitrogen that are key building blocks in all plant life. Contains freshwater algae.

ANTIOXIDANT | An additive known to attach to – and shut down – free radicles.

CHLOROPHYLL | A natural compound present in green plants that gives them their color. It helps plants to absorb energy from the sun as they undergo the process of photosynthesis.

IRON | Critical to respiration and photosynthesis in all plants.

SOIL MICROBES | Without microbes, plants wouldn’t have the constant supply of nutrients they need to grow. Beyond nutrient cycling, microbes produce hormones and other chemicals to stimulate plant growth, improve the soil, and support plant health.

SULFUR | Used in the formation of amino acids, proteins, and oils. It is necessary for chlorophyll formation.

TRANSLOCATION | Translocation in plants occurs in the vascular tissue known as phloem. Translocation is the movement of materials from leaves to other tissue throughout the plants. Without translocation, the food prepared by the plant can’t reach other parts of the plant.
