Calcium cyanamide: Last updated: 31/05/2018 (Also known as: cyanamide calcium salt; nitrolime; lime nitrogen) These results suggest calcium cyanamide may be used as an effective tool to reduce leaf NO3– accumulation and to produce high quality lettuce in compliance with European Regulation No. longifolia, cv. 1. 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.

Log in with your society credentials Calcium cyanamide is excreted mostly as urea in the urine of rabbits [6]. The calcium cyanamide converts in the soil over various stages into ammonium nitrogen. Plants fertilized with 120CC had lower leaf NO3– content (41 and 18% in Aruba and 70 and 21% in Manavert in Exp-1 and Exp-2, respectively) compared with those fertilized with 120SN. Leaf nitrate (NO3–) content was on average 55 and 41% higher in Aruba than in Manavert in the first (Exp-1) and second (Exp-2) season, respectively.

There is described a nitrogen fertilizer based on granulated calcium cyanamide, the granules being composed of (a) a core containing 35 to 94% by weight of calcium cyanamide and (b) a shell containing 5 to 30% by weight of a calcium carbonate compound, 0.5 to 20% by weight of urea and/or ammonium salts and 0.5 to 15% by weight of anhydrous binder. An unfertilized control (0-N) was included to calculate NUE indices. 2E).

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. The main use of calcium cyanamide is in agriculture as a fertilizer. At harvest leaf area index, dry weight, fresh yield, dry matter concentration, and NUE indices were not affected by the N source. 2.5 and you may need to create a new Wiley Online Library account. In contact with water it decomposes and liberates ammonia: CaCN2 + 3 H2O → 2 NH3 + CaCO3 It was used to… Fertilizer-grade calcium cyanamide, which has a nitrogen content of 18–22 percent, is effective in acidic and slightly basic soils when applied during autumn plowing. At harvest leaf area index, dry weight, fresh yield, dry matter concentration, and NUE indices were not affected by the N source. / Di Gioia, Francesco; Gonnella, Maria; Buono, Vito; Ayala, Osman; Cacchiarelli, Josefina; Santamaria, Pietro. 2.5.

Calcium cyanamide did not improve lettuce crop N use efficiency. An unfertilized control (0-N) was included to calculate NUE indices. 1258/2011 while assuring competitive yields. It is the calcium salt of the cyanamide (CN22−) anion.
