Is cobalt essential for plant growth?

Answer 1

An essential element would be one which would be required by all the plants for completing their life cycle. I have not yet read any article which would put cobalt into this category, however it is considered beneficial element i.e. an element which would be required for the optimum growth of the plant. It is also essential for some of the leguminous species but that also is because of their symbiotic association with the bacteria which require cobalt to fix nitrogen as it possess Vit B12 which contain Co. hope this would help you. I am also looking for its key role in plants if you find any article please do send me a link.

Answer 2

They need copper because it speeds up respiration and photosynthesis Without copper the plant would have stunted growth and the leaves would be lim (e.g they wouldn't stand and face the sun like usual).

Answer 3

Yes, cobalt is essential for plant growth as it is a component of vitamin B12, which is required for various metabolic processes in plants. Cobalt also plays a role in nitrogen fixation in leguminous plants by aiding the function of nitrogenase enzymes. However, plants require only very small amounts of cobalt for their growth.

Answer 4

microorganisms convert cobalt into vitamin B12

Answer 5

Cobalt is an essential trace dietary mineral for all animals. Cobalt in inorganic form is also a micronutrient for bacteria, algae and fungi.
