2012-8-1 · 1. Introduction. Manganese (Mn) is an essential plant nutrient (Bertrand, 1905) required as a cofactor by a wide range of key-proteins in all higher plants, including the oxygen evolving complex (OEC) of photosystem II.Manganese is currently receiving much attention in agriculture due to the frequent occurrence of Mn deficiency in many soils used for crop

The problem, and large opportunity of manganese
2020-6-11 · The problem, and large opportunity of manganese availability. Most agricultural soils today do not supply adequate levels of manganese to a crop. This is a foundational problem, because of the need for manganese in the water hydrolysis process at the beginning of photosynthesis. When water is absorbed from the soil, and used for photosynthesis ...

4. Manganese. 4.1. Availability of Mn in the rhizosphere. Availability of Mn to plants depends on its oxidation state: the oxidized form (Mn 4+) is not available to plants, whereas the reduced form (Mn 2+) is. Generally, oxidation reactions are mostly biological, but reduction may be either biological or chemical in nature (Rengel, 2000).
