The elements N P and K are the most common [[Fertilizer\|fertilizers]] for plant production on Earth. They are usually provided as compounds than can be absorbed by plants, and then by animals and humans. [[Calcium]] as a fertilizer is usually delivered on its own.

			Note that the "CHNOPS" elements (Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorous, & Sulphur), plus table salt (Sodium Chloride) make up over 99.99% of animal tissue. Of these, the rarest one is phosphorous, so phosphorous deposits would be of great interest to a large and expanding society on Mars. If economic amounts of phosphorous are found on Mars, it might make a valuable export to any colonies in the asteroid belt.

	For example, a future settlement might house 1000 people, massing about 70kg x 1000 = 70 000 kg, or 70 tonnes. So the 'Others' part of the above table, that covers all trace elements required for humans, is about 700 kg for that population of 1000 people. So, until the Mars settlement is entirely independent from Earth, a mass of a few hundred kg per year will be enough to cover the people's needs in trace elements. And a few tonnes might be enough for an entire settlement ecosystem.		For example, a future settlement might house 1000 people, massing about 70kg x 1000 = 70 000 kg, or 70 tonnes.
