Mangan-ion®: Ionic Manganese

The role of manganese in plants

• Manganese plays an important role in the production of amino acids and proteins, in lignin synthesis, in the activation of many enzymes (more than 35), in regulating the level of plant hormones, in respiration and in nitrogen metabolism, in the reduction of nitrates and their use by plants, in the formation of chlorophyll and in photosynthesis.
• A deficiency of manganese may adversely affect the volume of plant crown and the size and color of fruits
• After iron which is needed in plants at a quantity of 100mg iron / kg dry plant matter, manganese is the next trace element in terms of necessity for plants with a quantity of 50mg Manganese/ kg of dry matter
• Manganese Mn²⁺ is easily converted to Mn³⁺ or Mn⁴⁺ and therefore it plays an important role in plants in redox processes, such as photosynthesis, as an electron transport system. Possible deficiency may adversely affect the total volume of plant crown, the size and color of fruits and the total volume of production
• Deficiency of manganese is quite common and widespread in Greek soil conditions, to a level almost similar to iron deficiency. However, it often goes unnoticed or underestimated by farmers. It usually occurs in alkaline and calcareous soils with a high pH (over 6.5) and with poor aeration, in calcareous soils with medium or high organic matter content, in sandy soils as well as in soils resulting from parental rock poor in manganese
• Manganese deficiency often appears together with that of zinc or iron due to the similar soil conditions that favor deficiency of these three important nutrients
• Manganese is an extremely immobile element in plants and therefore symptoms of its deficiency appear first on young leaves in the form of interveinal chlorosis which can be confused with that of iron. However, iron deficiency causes a distinctly more acute and evident contrast between the green nerves and the chlorotic areas while that of manganese is more diffuse and confusing. Also, the symptoms of manganese deficiency resemble those of magnesium with the difference that in the latter symptoms appear on older leaves

What is Mangan-ion?

• Mangan-ion is a liquid fertilizer with strong acid reaction, containing concentrated mono-hydrate manganese sulfate (MnSOM₄-H₂O), in a hydrated ionic form of high bioavailability and efficacy, which is used against manganese deficiency
• The content of Mangan-ion in manganese is 9.1% w/v or 9.1 grams of elemental manganese in 100ml Mangan-ion
• Mangan-ion can be applied to crops throughout the vegetative period at very small rates: 1) foliarly at 50-100ml/100L of water and 2) through drip irrigation systems at 1-2L / ha
• Application rates vary depending on the crop, size and age of plants, application equipment and the orchard/crop training system
• Mangan-ion is a fully water-soluble fertilizer without mixing problems in spray or in liquid fertilizer tanks. It reduces the pH of the spray solution thus facilitating the mixing of other active substances that «prefer» acidic pH conditions
• It is compatible with most agro-chemical products. It is not compatible with unstable products in mixtures such as fosetyl-Al and chlorpyrifos
