Abstract:The paper describes the model software REPRO (REPROduction of soil fertility) designed for analyzing interlinked carbon (C) and nitrogen (N) fluxes in the system soil–plant–animal–environment. The model couples the balancing of C, N and energy fluxes with the target to estimate the climate-relevant CO2, CH4 and N2O sources and sinks of farming systems. For the determination of the net greenhouse effect, calculations of C sequestration in the soil, CO2 emissions from the use of fossil energy, CH4 emissions from… Show more
“…The results indicate that GHG emissions from conventional and organic agriculture are relatively equivalent for fuel consumption and machinery use (Küstermann et al, 2007). The study revealed that the major defining difference is conventional farming produces an additional 637 kg CO 2 -eq ha −1 yr −1 of GHG emissions, which is primarily caused by the manufacturing of nitrogen fertilizer and pesticides (Küstermann et al, 2007).…”

“…A separate study in the Federal Republic of Germany tested GHG emissions on 90 farms with the aim to improve the field of research and the management of commercial farms (Küstermann et al, 2007). The results indicate that GHG emissions from conventional and organic agriculture are relatively equivalent for fuel consumption and machinery use (Küstermann et al, 2007).…”

“…But the human activities have altered the chemical composition of the atmosphere through the buildup of greenhouse gasesprimarily carbon dioxide, methane, and nitrous oxide. Bjorn [1] has published paper on Modeling carbon cycles and estimation of greenhouse gas emissions from organic and conventional farming systems. It gives information on carbon (C) and nitrogen (N) fluxes in the system soil-plant-animal-environment [2] .…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
