Biomin Manganese

Biomin Manganese

Biomin Manganese is an amino acid chelated manganese powder (18.0% manganese) for correcting manganese deficiency through the soil or as a foliar spray. It suits growers with a soil or leaf test showing manganese is short, including crops on alkaline soils.

At a glance

• Type: chelated trace element (soluble powder)
• Supplier certificate on file: BioGro licence 3844. See the certificate and its dates.
• Analysis: manganese 18.0, nitrogen 4.8 (percent w/w)
• Use for: correcting manganese deficiency, including citrus and crops on alkaline soils
• Rate: soil 1.5 to 3 kg per hectare; foliar 1.0 to 1.5 kg per hectare
• Certification: BioGro 3844

What it is

Biomin Manganese is sourced from Roots, Shoots and Fruits and is part of the Biomin range of amino acid chelated minerals. The nitrogen on the label comes from the amino acid chelate. It dissolves in water for irrigation or spraying.

What it does

• Manganese is used in photosynthesis, where it splits water, and in several enzyme systems.
• Deficiency shows as speckled or mottled young leaves.
• Manganese becomes less available to roots as soil pH rises, so deficiency is common on alkaline and heavily limed soils. A chelated foliar spray gets around the soil in those cases.
• Suitable during deficiency and at times of high demand, for example in citrus.

Analysis

• Manganese (Mn) 18.0 percent w/w
• Nitrogen (N) 4.8 percent w/w, as amino acid

How to use

• Soil: apply before or at planting through irrigation water at 1.5 to 3 kilograms per hectare, depending on crop, soil conditions and application method.
• Foliar (all field crops: grain crops, pasture, flowers): 1.0 to 1.5 kilograms per hectare when crops are 15 to 30 cm high, or when deficiency symptoms appear. Repeat as needed.
• Manganese has a narrow margin between enough and too much, especially on acid soils: apply from a soil or leaf test and do not exceed the rate.
