Molybdenum deficiency (plant disorder) - Wikipedia

Molybdenum (Mo) deficiency occurs when plant growth is limited because the plant cannot take up sufficient quantities of this essential micronutrient from its growing medium. For crops growing in soil, this may be a result of low concentrations of Mo in the soil as a whole (i.e. the parent material of the soil is low in Mo), or because the soil Mo is held in forms that are not available to plants – sorption of Mo is strongest in acid soils.

Nitrogen fixation - Wikipedia

Nitrogen fixation is a chemical process by which molecular nitrogen (N 2) in the air is converted into ammonia (NH 3) or related nitrogenous compounds in soil or aquatic systems. Atmospheric nitrogen is molecular dinitrogen, a relatively nonreactive molecule that is metabolically useless to all but a few microorganisms.Biological nitrogen fixation or diazotrophy is an important microbially ...
