Nitrogen (N) is a nutrient element necessary for plant growth and development. However, excessive inputs of N will lead to inefficient use and large N losses to the environment, which can adversely affect air and water quality, biodiversity and human health. To examine the effects of controlled-release fertilisers (CRF) on yield, we measured ammonia volatilisation, N use efficiency (NUE) and photosynthetic rate after anthesis in summer maize hybrid cultivar Zhengdan958. Maize was grown using common compound fertiliser (CCF), the same amount of resin-coated controlled release fertiliser (CRFIII), the same amount of sulphur-coated controlled release fertiliser (SCFIII) as CCF, 75% CRF (CRFII) and SCF (SCFII), 50% CRF (CRFI) and SCF (SCFI), and no fertiliser. We found that treatments CRFIII, SCFIII, CRFII and SCFII produced grain yields that were 13.15%, 14.15%, 9.69% and 10.04% higher than CCF. There were no significant differences in grain yield among CRFI, SCFI and CCF. We also found that the ammonia volatilisation rates of CRF were significantly lower than those of CCF. The CRF treatments reduced the emission of ammonia by 51.34% to 91.34% compared to CCF. In addition, after treatment with CRF, maize exhibited a higher net photosynthetic rate than CCF after anthesis. Agronomic NUE and apparent N recovery were higher in the CRF treatment than in the CCF treatment. The N uptake and physiological NUE of the four yield-enhanced CRF treatments were higher than those of CCF. These results suggest that the increase in NUE in the CRF treatments was generally attributable to the higher photosynthetic rate and lower ammonia volatilisation compared to CCF-treated maize.

“…Several studies have been conducted to estimate N loss through NH j-N volatilization from inorganic N fertilizers applied to agricultural lands (Wang et al, 2004;Pacholski et al, 2006). The economic impact associated with NH3-N emission from N fertilizers applied to agricultural land is estimated at U.S. $11.6 billion dollars annually worldwide (FAO/IFA, 2001).…”

New N fertilizer products-organically enhanced NS plus and organically enhanced NS plus with Fe, manufactured by using sterilized and chemically converted organic additives extracted from municipal wastewater biosolids, were evaluated for N mineralization, ammonia (NH3-N) volatilization, N leaching, and effects on soil acidification, relative to urea. Laboratory incubations at three temperatures (20, 30, and 40°C), two leaching schemes (continuous and intermittent irrigation regimes), and ammonia volatilization experiments under aerobic (upland) and anaerobic (flooded) conditions were conducted in four appropriate soils (Greenville loam [

“…Similarly, emissions from feces and urine were measured from cattle manure patties placed in hayed paddocks and synthetic urine patches in an adjacent un-grazed alleyway . (ii) difference in time periods: the model estimated CH 4 release over the course of a year from the volatile solids deposited during the grazing season, whereas emission factors used to estimate measured CH 4 release from cattle feces were derived from relatively few fecal CH 4 emissions over the course of approximately 1 mo in each of 2004). The measured estimates, therefore, may underestimate cumulative emissions.…”

“…Indirect N 2 O emissions, via re-deposition of ammonia volatilized from applied liquid hog manure and urine deposited on pasture by grazing cattle, were calculated using a default emission factor (0.01 kg N 2 O-N kg (1 N; IPCC 2006). Ammonia volatilization following manure application was measured for a 3-wk period on the hayed field in the fall and spring of 2006 using the semi-open, adsorption chamber method (Wang et al 2004). Accordingly, emission factors were calculated from the measured volatilization values of 0.143, 0.144 kg NH 3 -N kg (1 N applied as hog manure for the split and single treatments, respectively ; Table 3).…”

2014. Whole-farm greenhouse gas emissions from a backgrounding beef production system using an observation-based and model-based approach. Can. J. Anim. Sci. 94: 463Á477. Backgrounding, raising weaned beef cattle in preparation for finishing in a feedlot, is a common practice in western Canadian beef production systems. The objectives of this study were: (i) to assess the whole-farm greenhouse gas (GHG) emissions from a pasture-based backgrounding system using an observation-based and model-based approach and (ii) to compare model-based estimated emissions with observation-based emissions from the key components of the farm, in order to identify the knowledge gaps that merit further study. For the observation-based approach, emissions were garnered from a multi-disciplinary field study that examined three fertility treatments applied to the pasture grazed by beef cattle: (i) no liquid hog manure application (control); (ii) split application of liquid hog manure, half applied in fall and half in spring (split) and (iii) single spring application of liquid hog manure (single). The model-based approach used a systems-based model, adapted from Intergovernmental Panel on Climate Change algorithms, to estimate annual net farm GHG emissions from the three fertility treatments and a hypothetical synthetic fertilizer treatment. Total farm emissions included methane (CH 4 ), nitrous oxide (N 2 O) emissions from farm components and carbon dioxide (CO 2 ) emissions from energy use. Net farm GHG emissions using the observation-based approach ranged from 0.4 to 2.2 Mg CO 2 eq ha (1 and from 4.2 to 6.5 kg CO 2 eq kg (1 liveweight gain exported; the model-based approach resulted in net farm emissions ranged from 0.6 to 3.7 Mg CO 2 eq ha (1 and from 7.0 to 12.9 kg CO 2 eq kg (1 liveweight gain exported. Except in the control treatment, both enteric CH 4 and soil N 2 O emissions were the major contributors to total farm emissions. Emissions intensity for the hypothetical synthetic fertilizer treatment (9.4 kg CO 2 eq kg (1 liveweight gain) was lower than for the split and single scenarios. Although individual GHG emission estimates varied appreciably, trends in emissions intensity were similar between the two approaches. Efforts to reduce GHG emissions should be directed towards components such as enteric CH 4 and soil N 2 O, which have larger impacts on overall system emissions.
