Molybdenum deficiency (plant disorder)
From Wikipedia, the free encyclopedia
This article is about molybdenum deficiency in plants. For the same deficiency in animals, see molybdenum deficiency.
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.
