Properties:
This product is soluble in water,
methanol, ethanol, amyl alcohol and liquid ammonia, easy
deliquescence in air. Agriculture used as acidic soil phosphorus
fertilizer. It can be applied more
smoothly to acidic soil, the calcium in fertilizer can counteract acidity in the soil.
The calcium nitrate in water should be colorless, solution
generally determined by the metal ions. Copper ion solution for
blue. Iron ion solution for yellow. Containing ferrous ion
solution for light green. Other general colorless.
In fruit trees, spraying, spraying calcium nitrate concentration
was 0.5% - 1% on vegetables.
Agricultural calcium nitrate types: nitrogen *5.5% or higher,
calcium oxide *8.0% or higher, apply to apple, tomato, corn
*1.0% or higher agricultural calcium nitrate: nitrogen *3% or
higher, calcium oxide, magnesium 3.5% or higher, apply to the
apples, tomatoes, wheat
Agricultural calcium nitrate: nitrogen *1% or higher, calcium
oxide *3% or higher, ornamental fruits and vegetables
