Calcium Nitrate 1kg

Trace element used in fertilisers and hydroponic nutrients.

Calcium nitrate, also called Norgessalpeter (Norwegian saltpeter), is the inorganic compound with the formula Ca(NO3)2. This colourless salt absorbs moisture from the air and is commonly found as a tetrahydrate. It is mainly used as a component in fertilizers but has other applications. Nitrocalcite is the name for a mineral which is a hydrated calcium nitrate that forms as an efflorescence where manure contacts concrete or limestone in a dry environment as in stables or caverns. A variety of related salts are known including calcium ammonium nitrate decahydrate and calcium potassium nitrate decahydrate.

Fast growing plants require large amounts of calcium and often require as much calcium as any one of the macro nutrients. In soils dolomite addition is a successful way of treating deficiencies. Deficiency thus displays first in the new growth where leaf tips tend to die back and new leaves show a brown to black scorching Calcium supports the cell walls and is an important part of the plant root structure. It is not very mobile and is thus more concentrated in the older growth. Calcium is fundamental in cell growth and is responsible for cell integrity and membrane permeability which ensures proper flow of nutrients. Roots must have calcium present at their tips.

Deficiencies symptoms of Calcium progression:

• Young leaves turn a very dark green
• Growth is slow and new shoots are discoloured
• New shoots are misshapen, shrivel and die
• Bud development is very slow
