How Vital Is Cobalt To The Growth Of Plants?

Cobalt (Co) is a crucial micronutrient for the growth of many lower plants, such as marine algal species and higher plants in the Fabaceae or Leguminosae family. It plays a vital role in nitrogen fixation by symbiotic microbes, primarily rhizobia. Cobalt is essential for the growth of many lower plants, such as marine algal species, and has been shown to enhance plant growth and yield characteristics by improving nitrogen fixation ability and nutritional quality.

Cobalt is a transition element, an essential component of several enzymes and co-enzymes. It has been shown to affect growth and metabolism of plants in different ways. Cobalt deficiency is common in arid and semi-arid climatic regions suitable for growing moringa (Moringa oleifera Lam), an economically important plant. Cobalt at appropriately low concentrations can enhance plant growth and performance.

Cobalt plays a critical role in the overall growth process of plants, including stem growth, elongating coleoptiles, and expanding leaf discs. It is also necessary for a plant to reach maturity and for healthy bud development. Cobalt is a critical component of vitamin B12 (cobalamin), which is essential for the proper functioning of nitrogen-fixing bacteria.

Cobalt is essential for lower plants, such as non-vascular plants like bryophytes and algae, and for symbiotic bacteria in nitrogen fixation. Its specific requirement is to increase stem growth, metabolism, transpiration, and other functions to improve crop yield. Some observed beneficial effects of cobalt include slowing leaf senescence, keeping leaves on plants longer, and helping plants survive.

In conclusion, cobalt is a tiny but powerful nutrient essential for plant health, playing a crucial role in nitrogen fixation and vitamin production.

How does cobalt help the environment?

Cobalt is crucial in the production of green energy, which accounts for 25% of global emissions. It is essential in batteries used to store and generate green energy, such as wind power. As transportation decarbonization progresses, the demand for energy storage and rechargeable batteries is increasing, with the goal of achieving zero emissions. Cobalt is also essential in the electrification of mobility, as it is a key component in lithium-ion batteries and smart mobility electronics.

It ensures higher energy density, improves battery life, and determines the range and durability of electric vehicles. Governments worldwide are working towards decarbonizing the global economy, with strategies such as banning the sale of internal combustion engines, such as those in diesel and petrol cars, set to happen as early as 2030. The European Green Deal, for example, decouples economic growth from fossil fuels and aims to have no net emissions of greenhouse gases by 2050. This has led car manufacturers to transition their entire fleets to electric vehicles, including fuel cell technology.

Why is cobalt an essential nutrient?

Cobalt is a hard, gray metal element that is found in vitamin B-12. It is essential for the production of red blood cells and the maintenance of the nervous system. Cobalt performs analogous functions to manganese and zinc, serving as a substitute for manganese in the activation of biochemical reaction mediators and as a replacement for zinc in certain reactions. Cobalt is only present in the body in conjunction with vitamin B-12.

What is cobalt essential for the growth of?

Cobalt, a transition metal in the fourth row of the periodic table, is an essential element for prokaryotes, humans, and mammals. However, its essentiality for plants remains unclear. This article proposes that cobalt (Co) is a potentially essential micronutrient of plants, essential for the growth of many lower plants, such as marine algal species and higher plants in the Fabaceae or Leguminosae family. Cobalt’s role in nitrogen fixation by symbiotic microbes, primarily rhizobia, is attributed to its role in cobalamin or vitamin B 12, which is required by several enzymes involved in N 2 fixation.

In addition to symbiosis, diazotrophs, a group of N 2 fixing bacteria, can be found in plant tissue as endophytes or closely associated with roots of economically important crops like barley, corn, rice, sugarcane, and wheat. Their action in N 2 fixation provides crops with the macronutrient of N. Co is a component of several enzymes and proteins, participating in plant metabolism. Plants may exhibit Co deficiency if there is a severe limitation in Co supply. Conversely, Co is toxic to plants at higher concentrations, resulting in pale-colored leaves, discolored veins, and leaf loss, and can also cause iron deficiency in plants.

The confirmation of Co as an essential micronutrient will enrich our understanding of plant mineral nutrition and improve our practice in crop production. With the advance of omics, Co as a constituent of enzymes and proteins and its specific role in plant metabolism will be exclusively revealed. This confirmation will enrich our understanding of plant mineral nutrition and improve our practice in crop production.

What is the role of cobalt in soil?

Cobalt, a crucial element for animal and human nutrition, is essential for nitrogen fixation by Rhizobium and indirectly required by legumes. In practical agriculture, the availability of cobalt in different soils is crucial for efficient nitrogen fixation and ruminant nutrition. In Ireland, soils with low levels of cobalt are formed mainly from acid igneous rocks, sedimentary rocks, and metamorphic rocks. Peat soils are also inherently low in cobalt.

Low-cobalt soils (less than 5 mg/kg) have been mapped by Walsh et al. 1952, indicating high risk areas for cobalt deficiency in stock. However, these maps do not reveal the true extent of risk areas. Many soils have high total cobalt contents but poor pasture availability, particularly in limestone and shale soils, due to the high content of soil manganese.

Manganese dioxide minerals often occur in soils in extremely finely divided forms, resulting in their absorptive capacity being out of proportion to their mass content. The crystal structures of these compounds allow cobalt ions to be readily accommodated into stable structures, limiting the availability of cobalt in high Mn soils even in soils with high total Co contents.

Why is cobalt necessary?

As we move towards a zero-emissions future, demand for rechargeable batteries and energy storage is increasing. Cobalt is crucial in the cathodes of Lithium-ion batteries, as well as in the petro-chemical industry for catalysts to remove impurities from crude oil, reducing greenhouse gas emissions. Cobalt also offers advantages in the hard metal industry, allowing manufacturers to produce effective cutting and grinding tools suitable for various industrial and manufacturing applications.

Its high temperature resistance, hardness, and wear characteristics are used in superalloys for gas turbines and hard surfacing in critical environments, improving wear and durability, extending operating life, and reducing friction.

Why is cobalt so important?

Cobalt is a crucial element in the production of rechargeable batteries for electric vehicles, portable devices like phones, tablets, and laptops, and a bio-essential element found in vitamin B12. It can be magnetized and used in magnets, particularly when alloyed with aluminum and nickel. Cobalt salts have been used for centuries to produce brilliant blue colors in paint, porcelain, glass, pottery, and enamels. Cobalt contributes to a greener society by acting as a catalyst in desulphurization reactions and lowering activation energy needed for industrial processes.

The Cobalt Institute and its members are committed to sustainable and responsible sourcing of cobalt, ensuring health and safety conditions for industrial miners and rewarding livelihoods for their workforce. Significant efforts are being made to formalize artisanal and small-scale mining to ensure ethical cobalt sourcing.

How much cobalt do plants need?

The potential benefits of trace amounts of Co for certain plants remain to be elucidated, as the concentration of beneficial Co is currently unknown. The typical range of cobalt concentrations in forage dry matter is 0. 01 to 0. 5 ppm. Forage mixtures should contain at least 0. 1 ppm Co to ensure adequate levels of this essential element.
