"When nitrogen is passed over calcium carbide at a suitable high temperature, we
get a mixture called nitrolim which is a nitrogenous fertiliser."

So I guess they use it for farming? Because fertilizers need nitrogen because nitrogen is good for plants...

"Calcium cyanamide (NITROLIM, calcium carbimide, cyanamide) is a blackish-grey, shiny powder used in agriculture as a fertilizer, herbicide, pesticide and a defoliant for cotton plants. It is also used in steel hardening and as a desulphurizer in the iron and steel industry. In industry, calcium cyanamide is used for the manufacture of calcium cyanide and dicyandiamide, the raw material for melamine."

What do you need to know this for?

This class of compounds is characterized by the presence of a CN (cyano) group and includes the cyanides and nitriles (R-CN) as well as related chemicals such as cyanogens, isocyanates and cyanamides. They primarily owe their toxicity to the cyanide ion, which is capable of inhibiting many enzymes, especially cytochrome oxidase, when released in the body. Death, which may be more or less rapid depending on the rate at which the cyanide ion is released, results from chemical asphyxia at the cellular level.

Inorganic cyanides are readily hydrolyzed by water and decomposed by carbon dioxide and mineral acids to form hydrogen cyanide, which can also be produced by certain naturally occurring bacteria. Hydrogen cyanide is evolved in coke and steel-making, and can be generated in fires where polyurethane foam is incinerated (e.g., furniture, partitions and so on). It can be generated accidentally by the action of acids on cyanide-containing wastes (lactonitrile evolves hydrocyanic acid when in contact with an alkali, for example.), and intentionally in gas chambers for capital punishment, where cyanide pellets are dropped into bowls of acid to create a lethal atmosphere.

The calcium cyanamide(cacN2) is commercially known as Nitrolim.It is largely used as fertilizer.

It is a mixture of Calcium Cyanamide [ CaNCN ] & Carbon.Heated Calcium Carbide [ CaC2] reacts with nitrogen at 1373K to yield Calcium Cyanamide [ CaNCN ] & Carbon. The mixture of Calcium Cyanamide [ CaNCN ] & Carbon is brown coloured & its commercial name is Nitrolim. It is used as a chemical fertiliser as it contains nitrogen necessary for plants to grow. Calcium Cyanamide [ CaNCN ]undergoes hydrolysis with superheated steam to yield ammonia & Calcium carbonate.
CaC2+N2= CaCN2+C
CaCN2+3H2O=CaCO3+2NH3

Nitrolim is calcium cyanamide (CaNCN), a nitrogen fertilizer.
