Not all greenhouse gases are the same. One of the unfortunate things about agriculture is that it's a major source of nitrous oxide, via fertilizer decomposition, and methane, via mostly cattle. Both N2O and CH4 are drastically more potent GHG than CO2, essentially because the atmospheric concentration of those gases is already much lower, so the proportional impact of N2O/CH4 emissions is much greater. CH4 emissions from agriculture could be potentially reduced by improving manure treatment on farms (because untreated manure releases CH4) and regulating feed quality. Both have the side-effect of higher meat prices. N2O emissions are harder: you'd have to stop using nitrate-containing fertilizer.
