Calcium: A Central Regulator of Plant Growth and …

EARLY STUDIES ON PLANT CALCIUM Ca 2+ is an essential element; however, its role is elusive. When examining total Ca 2+ in plants, the concentration is quite large (mM), but its requirement is that of a micronutrient (μM). Ca 2+ is not usually limiting in field conditions, still there are several defects that can be associated with low levels of this ion, including poor root development, leaf

Corrosionpedia - What is Calcium Hypochlorite? - …

2018/5/15· Calcium hypochlorite is generally sold as 68% calcium hypochlorite coined with calcium chloride and other salts. It is used as a sanitizer in outdoor swimming pools. The calcium content hardens the water and tends to clog up filters; hence, some products containing calcium hypochlorite also contain anti-scaling agents.
