    From atoms to landscapes through time: the chemical controls on carbonate precipitation and phosphate concentration in alkaline lakes by Pietzsch, R

    Published 2022
    “…This is likely the result of the high primary productivity taking place in these modern environments, in part due to the large availability of carbon as dissolved inorganic carbon (DIC) but also of other limiting nutrients such as nitrogen and phosphate itself. Conversely, ammonia volatilisation, a phenomenon that may occur as a result of high alkalinity in some lakes, may limit productivity, thereby allowing phosphate levels to increase without this constrain. …”
