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.
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).
microorganisms convert cobalt into vitamin B12
Cobalt is an essential trace dietary mineral for all animals. Cobalt in inorganic form is also a micronutrient for bacteria, algae and fungi.
potassium is a good plant fertiliser, basically its essential!

nitrogen
Artificial fertilizers provide radilly the essential elments like nitrogen, phosphorus and potash for plant growth.
Nitrates are essential for the growth of amino acids and therefore are essential for the production plant proteins, which help the plant to grow :)

Plants require a variety of essential elements for growth and primary function. The 17 most important ones include Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus, potassium, calcium, Magnesium, Sulphur, Boron, Copper, Iron, Manganese, Zinc, Chlorine, Cobalt and Nickel.
An auxin is a class of plant growth substance which plays an essential role in coordination of many growth and behavioural processes in the life cycle of a plant.
