A Guide to Information on Greenhouse Gases and Ozone Depletion
Published July 1988 through June 1999
FROM VOLUME 6, NUMBER 3, MARCH 1993
ANTHROPOGENIC EMISSIONS AND CONTROL: METHANE
"The Greenhouse Effect and United States Landfill Methane," D.
Augenstein (Emcon Assoc., 1921 Ringwood Ave., San José CA 95131), Global
Environ. Change, 2(4), 311-328, Dec. 1992. Preliminary estimates
suggest that landfill methane abatement is one of the more cost-effective
measures for addressing the greenhouse problem.
Two items from Soil Sci. Plant Nutrition, 38(4), Dec.
"Methane Production and its Fate in Paddy Fields. 1. Effects of Rice
Straw Application and Percolation Rate on the Leaching of Methane and Other Soil
Components into the Subsoil," M. Kimura (Sch. Agric., Nagoya Univ., Chikusa
Ku, Nagoya 46401, Japan), Y. Miura et al., 665-672. Describes results of soil
"Suppression of Methane Fluxes from Flooded Paddy Soil with Rice Plants
by Foliar Spray of Nitrogen Fertilizers," M. Kimura (addr. immed. above),
K. Asai et al., 735-740. Pot experiments evaluating effects of fertilizer type
(ammonium sulfate, ammonium chloride, urea) and method of topdressing
(broadcasting, foliar spray) show that topdressing of ammonium sulfate is best,
considering both methane emissions and grain yield.
"Gas Leakage in the United Kingdom," M.K. Wallis (Sch. Math.,
Univ. Wales, Cardiff CF2 4AG, UK), Nature, 359(6394), 355, Oct.
1, 1992. Letter calling for monitoring of methane leakage from the fuel
industries, and extension of carbon/energy taxes to such leakage.
"Flux Chamber Design and Operation for the Measurement of Municipal
Solid Waste Landfill Gas Emission Rates," D.R. Reinhart (Civil Eng. Dept.,
Univ. Central Florida, POB 25000, Orlando FL 32816), D.C. Cooper, B.L. Walker,
J. Air Waste Mgmt. Assoc., 42(8), 1067-1070, Aug. 1992.
"Greenhouse Gas Contributions from Coal Mining in Australia and New
Zealand," B.B. Beamish (Coalseam Gas Res. Inst., James Cook Univ.,
Townsville, Queensland 4811, Australia), W.E. Vance, J. Roy. Soc. N. Zealand,
2(2), 153-156, June 1992. This analysis shows that mining emissions of
methane, CO2 and CO are grossly miscalculated in greenhouse gas inventories.
Methane emissions from coal seams are a wasted energy resource.
"Methane Prediction in Dry and Lactating Holstein Cows," J.B.
Holter (Dept. Animal Sci., Univ. New Hampshire, Durham NH 03824), A.J. Young,
J. Dairy Sci., 75(8), 2165-2175, Aug. 1992.
Experiments on the effects of diet on methane emissions yield a predictive
model suitable for evaluating the contribution of dairy cows to global warming.
"Greenhouse Gas Emissions from Pasture and Arable Crops Grown on a
Kairanga Soil in the Manawatu, North Island, New Zealand," J.R. Crush (N.Z.
Pastoral Agr. Res. Inst. Ltd., Private Bag 11008, Palmerston, N.Z.), G.C.
Waghorn, M.P. Rolston, N. Zealand J. Agric. Res., 35(3),
Measurements over a three-year period show that no-tillage cropping of this
site contributes much less methane and CO2 to the atmosphere than either grazing
with ruminants or cropping with cultivation.
