Calcium cyanamide was the first mineral fertilizer that enabled atmospheric nitrogen to be used for plant nutrition. Learn more. Calcium acetylide is used in the manufacture of calcium cyanamide, CaCN2, by the reaction of CaC 2 with N 2 at high temperature. Since calcium cyanamide reacts with oxygen at high temperatures, all of these routes must be done in the absence of oxygen, thus an inert gas is often used. Today the multipurpose fertilizer still plays an important role in crop cultivation, because calcium cyanamide is the only fertilizer that contains the nutrient element nitrogen in the so-called NCN binding form.

Because of its negative effect on many soil borne diseases it is now often applied to prevent yield and quality losses during increasingly tight crop rotations. CaCN2 (calcium cyanamide) was the result of a biological process, the same as that for the conversion of urea into ammonium carbonate. In contact with water it decomposes and liberates ammonia: CaCN 2 + 3 H 2 O → 2 NH 3 + CaCO 3. Fertilizer, Agricultural chemicals. An unfertilized control (0‐N) was included to calculate NUE indices. Pretransplanting application of 120 kg ha−1 of N as calcium cyanamide (120CC) was compared with a traditional split application of 120 kg ha−1 of soluble N (120SN) consisting of 50% ammonium sulfate applied before transplanting and 50% as ammonium nitrate applied after transplanting. Calcium cyanamide definition is - a compound CaCN2 used as a fertilizer and a weed killer and as a source of other nitrogen compounds. The yield of cyanamide based on the calcium cyanamide in the starting lime nitrogen was 90 %, and the ratio of formation of dicyandiamide was 0.3 %. Calcium cyanamide is the inorganic compound with the formula CaCN 2. There was little evidence that calcium cyanamide was “slow acting” in comparison with sulphate of ammonia. A 2‐yr field study was conducted to evaluate the effects of calcium cyanamide as an alternative nitrogen (N) fertilizer source on N use efficiency (NUE), yield, and quality of two types of lettuce (Lactuca sativa L.), romaine (var.

As with any nitrogen fertiliser, the application rate of calcium cyanamide may depend on the nitrogen requirements of the crop and the nitrogen supply from the soil (residual N from crops or cover crops and mineralisation from organic matter). The Nitrogen supply corresponds to the natural growth demands of young plants, becoming increasingly available after application. Calcium cyanamide can reduce nitrate accumulation in lettuce crops. The direct fixation of nitrogen is brought about by heating the powdered calcium carbide in an atmosphere of nitrogen: Ca C 2 + N 2 = Ca N C N + C .
