For many years, commercial vegetable farmers have struggled with calcium insufficiency. The development of Ca-deficiency damage in plants is influenced by a number of factors.. First, several conditions influence Ca-uptake by plants such as the soil moisture content, the salt content of the soil solution, the oxygen content of the soil, soil temperature, the Ca-content of the soil, the cation/anion balance, and an inadequate rate of root production. Air temperature, CO2concentration, photoperiod, radiation level, relative humidity (RH), and/or diurnal fluctuations in water potential as well as other parameters, influence the development of Ca-injury in plants. CO2concentration, photoperiod, radiation level, relative humidity (RH), and/or diurnal fluctuations in water potential. Calcium is a necessary ingredient for plants.Calcium's fundamental purpose in plant growth is to reinforce cell walls structurally. Because calcium is not transportable inside the plant, transpiration is slowed.
