Application of microbially induced calcium …

Microbially induced calcium carbonate precipitation (MICP) is a natural biological process accompanied by different microbial activities and chemical processes. During MICP, subsequent precipitations of calcium carbonate occur as a result of microbial metabolic products like CO 3 2– that may react with Ca 2+ ions in the surrounding environment ( Anbu et al., 2016 ).

Carbonate Chemistry of the Oceans - Encyclopedia of Life ...

The calcium carbonate components of some phytoplankton and zooplankton also contribute to the downward flux of carbon. When shells sink, they are dissolved, causing CO2 to be regenerated at much greater depths. As carbonate is removed from the water, equilibrium must take place to restore carbonate and therefore increase CO2, leading to a potential reduction in the oceanic drawdown of ...

"Calcium Carbonate Production and …

Biological production of calcium carbonate in the oceans is an important process. Although carbonate is produced in the open ocean (pelagic, see Chapter 5), this chapter concentrates on production in coastal waters (neritic) because this contributes sediment to the coast through skeletal breakdown producing sand and gravel deposits on beaches, across continental shelves, and within …

Using Soluble Calcium to Stimulate Plant Growth

Research has shown that applying soluble calcium with urea, an ammonium form of nitrogen, can improve crop production. Calcium increases ammoni-um, potassium and phosphorus absorption, stimulates photosynthesis, and increases the size of sellable plant parts. It also makes the use of nitrogen more efficient, which improves the economics of production and reduces nitrogen contamination of …
