Cobalt, Molybdenum, and Selenium
Cobalt (Co), molybdenum (Mo), and selenium (Se) in soils are often determined because they are associated with nutritional disorders in animals that eat the plants. Problems affecting the nutrition of animals arise because the requirements and tolerances of plants for these trace elements differ from those of the animals eating the plants.

Molybdenum in Agriculture
Molybdenum (Mo) deficiencies in field-grown plants were first recorded more than 50 years ago and this book condenses all the information currently available on the subject of molybdenum as it relates to soils, crops and livestock. The book reviews our knowledge of the chemistry and mineralogy of Mo, the extraction of available Mo from various ...
Molybdenum Matters: How to Enhance Crop Performance
Plant-available molybdenum represents, on average, 2-20% of total molybdenum in soil. It binds to clay and organic colloids in the soil, making it resistant to leaching. Molybdenum's availability varies with soil pH. Its availability increases in alkaline soils, at a pH >7.5. However, in acidic soils, molybdenum binds strongly to iron and ...

Introduction. Many early studies reported the molybdenum (Mo) requirements of bacteria (Bortels, 1930; Horner et al., 1942), fungi (Steinberg, 1936, …
Molybdenum
Molybdenum in Irish Soils. Molybdenum (Mo) is essential for both plants and animals. The primary source of molybdenum in the weathering zone of the soil is the ferromagnesian minerals, with the sulphide molybdenum (MoS 2) common in certain granitoids (Chesworth, 1991). Molybdenum is soluble under a wide range of conditions, …

To treat a plant' s molybdenum deficiency, correct the soil's pH level by reducing the acidity and apply a molybdenum fertilizer. Molybdenum is an element that is necessary for plant growth. When a plant is deficient in …
Molybdenum (Mo) Uptake | SpringerLink
The average molybdenum content of the earth's crust is about 2 μg g −1 and of soil 0.2–5 μg g −1.Mo is found in various forms in soil, such as MoS 2, Fe 2 (MoO 4) 3, CaMoO 4 and PbMoO 4.The major form in which Mo is found in both acidic and alkaline soils is CaMoO 4.Molybdenum takes various forms in soil solution such as MoO 4 2−, HMoO 4 − and …
An Elegant Cycle: Molybdenum's Availability in Soil …
This finding suggests a molybdenum cycle: molybdenum in the soil is taken up by tree roots and deposited in leaves. These leaves fall to the ground and decompose, releasing molybdenum, which binds to tannins and tannin-compounds in soil. This solved one half of the mystery: by binding to tannins, molybdenum could be …

As shown in Figure 2.1, Mo solid phases dissolve upon contact with water and provide dissolved Mo in soil solution. The free molybdate ion reacts with metals to form complexes and ion pairs in soil solution. Plants absorb dissolved Mo, mainly as, from soil solution. Removal of by plants disrupts the electroneutrality of a soil solution.

Cobalt and molybdenum transport in plants
Climatic conditions and soil parameters like temperature of soil, pH, structure, and texture of soil also govern Mo uptake and distribution in plants. Therefore, irrespective of foliar Mo application or supplying molybdate in the soils, plants might not be able to actively transport Mo due to adverse soil and climatic factors (Gridley, 2003 ...

15.2.1 Uptake. The Mo-root contact is basically by mass flow, especially at higher soil concentrations. Typically, molybdenum is absorbed as MoO 4 2− when the pH of the medium is equal to or greater than 5.0, and as HMoO 4 − when the pH is lower than 5.0.. The absorption process is via symporter and the presence of other ions can affect …
