“…(Blaise, Amberger, and Tucher 1997;Carrasco et al 2004;De Datta 1981;Freney et al 1995). Field experimental results conducted by CSIRO (Commonwealth Scientific & Industrial Research Organization) using 15 N as the tracer at Griffith showed that use of encapsulated calcium carbide reduced denitrification significantly (Keerthisinghe et al 1996). Denitrification losses can also be decreased by deep placement of urea fertilizer (Ding et al 2002;Fillery and Vlek 1982).…”

Nitrogen (N) requirements of rice crop are met from both the soil and fertilizers. Because of acute N deficiency in most rice soils, fertilizer N must be applied to meet the crop demand. N fertilizer applied to rice crops is partially lost through different mechanisms, including ammonia volatilization, denitrification, and leaching. These losses may cause environmental problems such as polluting the atmosphere, aquatic systems, and groundwater. These problems cannot be alleviated completely. However, they can be reduced a considerable extent by various techniques. Research has been conducted around the world to minimize N fertilizer losses. This paper reviews this information on N fertilizer losses, indicating management practices for minimizing these losses from the soil-water system.

“…Several previous studies clearly indicated nitrification inhibitory properties of CaC 2 (Freney et al 1992;Freney et al 2000;Keerthisinghe et al 1993Keerthisinghe et al , 1996. The inhibitory effect of CaC 2 is attributed to its capacity to release acetylene which is considered a potent nitrification inhibitor (Smith et al 1993).…”

The aim of this study was to evaluate the relative performance of three nitrification inhibitors (NIs) viz. calcium carbide (CaC 2 ), and plant derivatives of Pongamia glabra Vent. ? -N and NO 3 --N were examined during the study. A second experiment was conducted in a glasshouse using pots to evaluate the response of wheat to these amendments. Results indicated that more than 92 % of the NH 4? initially present had disappeared from the mineral N pool by the end of incubation. Application of NIs i.e., CaC 2 , karanjin, and M. azedarach resulted in a significant reduction in the extent of NH 4? disappearance by 49, 32, and 13 %, respectively. Accumulation of NO 3 --N was much higher in N amended soil 57 % compared to 11 % in N ? CaC 2 , 13 % in N ? karanjin, and 18 % in N ? M. azedarach. Application of NIs significantly increased growth, yield, and N uptake of wheat. The apparent N recovery in N-treated plants was 20 % that was significantly increased to 38, 34, and 37 % with N ? CaC 2 , N ? karanjin, and N ? M. azedarach, respectively. Among the three NIs tested, CaC 2 and karanjin proved highly effective in inhibiting nitrification and retaining NH 4? -N in the mineral pool for a longer period.

Keerthisinghe et al (1996) and Randall et al (2001) reported improvement in yield of wheat, cotton, rice and maize crops in response to soil application of coated CaC 2, (CCC) which gradually released C 2 H 2 .

The potential of encapsulated calcium carbide (ECC) in improving growth, yield and physiology of cotton under salinity was evaluated in pot experiment. Salinity was induced by sodium chloride (NaCl) @ 0, 1250 and 2000 ppm. The ECC was applied at the rate of 0, 15, and 30 mg kg -1 soil. The results revealed that ECC improved number of branches, yield, shoot dry biomass, root dry biomass, by 57, 67, 40, 22, and 18% respectively, over control. Similarly, net photosynthesis, stomatal conductance nitrogen, phosphorus and potassium (N, P and K) Downloaded by [Texas A & M International University] at 21:40 16 August 2015 ACCEPTED MANUSCRIPT ACCEPTED MANUSCRIPT 2 concentration of shoot were enhanced by 38, 34, 7, 25 and 11% over control, respectively. The induction of new set of proteins ranging from 11 to 26 kDa was also observed at various levels of ECC and salinity stress. These results proved the efficacy of very lower concentrations of ethylene produced by ECC and showed the behavior of different parameters of cotton to it under saline stress.
