Phosphate is an essential nutrient on Earth, used by life for ATP, DNA, RNA, and phospholipid membranes. Therefore, if life is or ever was present on Mars, phosphorus may have played an important role in determining the habitability of an environment. Phosphorus does not have a significant volatile phase; its release from minerals is consequently critical to phosphorus …

Phosphate minerals comprise only a fractional percentage of the soil mass, perhaps averaging 0.02% or so, which impedes their direct identification by optical microscopy and x-ray analysis unless their concentration has been locally increased by addition of phosphate fertilizers.

The sequestration and release of phosphate by the cell under oxic and anoxic conditions, respectively, represent a mechanism by which microbes contribute to mineral formation because it generates locally elevated reactive phosphate concentrations in the vicinity of the cells that are high enough to induce precipitation of minerals.

Introduction: Phosphate as an Essential Mineral "The story of phosphorus is a long, fascinating one. But we are here interested primarily in knowing about its role in agriculture," wrote Vincent Sauchelli in "Manual on Phosphates in Agriculture" published in 1942. "Therefore in order to start at the beginning or our story we shall have to go back to the year 1840 – the year when ...

Minerals break down over time (a process referred to as weathering) and release phosphorus in the soil solution for plant uptake. Primary minerals such as apatite are very stable and resistant to weathering. Hence, phosphorus is released very slowly compared to secondary phosphorus minerals such as calcium, iron, or aluminum phosphates.
