Micronutrients: advances in understanding manganese cycling in soils, acquisition by plants and ways of optimizing manganese efficiency in crops

Micronutrients: advances in understanding manganese cycling in soils, acquisition by plants and ways of optimizing manganese efficiency in cropsManganese (Mn) is an essential micronutrient for all living organisms acting as a metal co factor for approximately 6% of all known metalloenzymes. Photosynthesis is very sensitive to disturbances in plant availability of Mn, and both Mn deficiency and toxicity lead to distinct disturbances within the photosystems. However, plants are typically affected by Mn deficiency without any visual symptoms, and massive yield reductions are often observed if Mn
