in the kyoto protocol, canada agreed to reduce its emissions to 94% of 1990 levels by 2008 to 2012.

the netherlands has decided that, by 2000, nh3 emissions must be no more than half of those in 1980.

les cycles gel-dŽgel inßuent aussi sur les Žmissions de n2o par les sols.
as a result, n2o can be produced all winter and be released through the porous snow.

as well, n2o may erupt immediately after fertilizer is applied because of the sudden availability of n.

heureusement, les agriculteurs peuvent prendre un certain nombre de mesures pour rŽduire les Žmissions.
there are two main ways of reducing emissions: one is to increase the amount of c stored in soil; the other is to burn less fuel.

lorsque le fumier est entassŽ, lÕintŽrieur du tas est mal aŽrŽ, ce qui peut provoquer des Žmissions de ch4.
most soils have enough aeration that they do not produce ch4; in fact, microorganisms in the soils convert ch4 to co2 so that the soils ÒabsorbÓ ch4.

les chercheurs ont mesurŽ les Žmissions de gaz ˆ effet de serre par du fumier de bovins de boucherie et du fumier de vaches laiti
scientists measured greenhouse gas emissions from beef and dairy manure each stored in three ways: compost, slurry, and stockpile.

current estimates suggest that n2o emissions have increased steadily since 1981, increasing by 20% from 1991 to 1996 alone.
