Cobalt in plants and soil - Plantprobs

Cobalt Cobalt is a trace element in plants (it has not been proven to be essential for plant life). It is a component of a number of enzymes and increases the drought resistance of seeds. In legumes, cobalt is important for nitrogen fixation by the bacteria that associate with legumes.

Cobalt | NIOSH | CDC

Cobalt (Co) is a hard, gray metal that occurs naturally. It is found in rocks, soil, water, plants, and animals, including people. It can harm the eyes, skin, heart, and lungs. Exposure to cobalt may cause cancer. Workers may be harmed from exposure to cobalt and cobalt-containing products. The level of harm depends upon the dose, duration, and work being done.

Copper and cobalt accumulation in plants: a critical ...

Cobalt accumulation is also observed in a limited number of nickel (Ni) hyperaccumulator plants occurring on ultramafic soils around the world. None of the putative Cu or Co hyperaccumulator plants appears to comply with the fundamental principle of hyperaccumulation, as foliar Cu–Co accumulation is strongly dose-dependent.

Cobalt-60 and the environment

Summary Cobalt-60 is a man-made activation product that normally occurs (with the shorter-lived isotopes 57 Co and 58 Co) in liquid effluent discharged from nuclear power and waste reprocessing plants. Its naturally-occurring stable isotope, 59 Co, plays a role in leguminous plant nitrogen nutrition and is a vital trace element for animals. As is the case for stable …

Seeds or other plant propagules (such as pollen, spores or stem cuttings) are typically treated for seconds or minutes with a cobalt-60 source, or are irradiated in X-ray machines. Whole plants or seedlings can also be irradiated, either in a gamma greenhouse or a gamma field. This process is called chronic irradiation.
