Calcium nitrate salt" 5Ca(NO).NHNO·10HO. This is called calcium ammonium nitrate. Formulations lacking ammonia are also known: Ca(NO)·4HO (11.9-0-0 + 16.9 Ca) and the water-free 17-0-0 + 23.6 Ca. A liquid formulation (9-0-0 + 11 Ca) is also offered. An anhydrous, air-stable derivative is the urea complex Ca(NO)·4[OC(NH)], which has been sold as Cal-Urea. Calcium nitrate is also used to control certain plant diseases. For example, dilute calcium nitrate (and calcium chloride) sprays are used to control bitter pit and cork spot in apple trees. Calcium nitrate is used in waste water pre-conditioning for odour emission prevention. The waste water pre-conditioning is based
Urinary calcium adult, the amount of calcium excreted in the urine is 100–250 mg over a 24-hour period. For those on low-calcium diets, there is normally 50–150 mg/24 hours, while those on a calcium-free diet will have 5–40 mg/24 hours. The following reference ranges are for persons with average calcium intake (600–800 mg/day for adults): An abnormally high amount of urinary calcium is called hypercalciuria and an abnormally low amount is called hypocalcuria. Urinary calcium Urinary calcium is calcium in the urine. It is termed -calcuria or -calciuria as a suffix. In a urinalysis, the normal amount of urinary calcium can be
