AbstractŠima T., Dubeová M., 2013. Eff ect of crop residues on CO 2 fl ux in the CTF system during soil tillage by a disc harrow Lemken Rubin 9. Res. Agr. Eng., 59 (Special Issue): S15-S21.Carbon dioxide is one of the most important greenhouse gases. Agriculture, especially soil tillage, contributes to CO 2 emissions signifi cantly. Th e aim of the paper was the comparison of the amounts of carbon dioxide emissions released from the soil into the atmosphere depending on the controlled traffi c farming (CTF) and crop residues. Th ree variants of the experiment were realised: before the soil tillage, immediately after the soil tillage, and seven days after the soil tillage. Th e soil tillage was carried out after the harvest of winter wheat by disc harrow Lemken Rubin 9 with a tractor John Deere 8230 on the loamy soil. Th e monitoring points were selected in parts of the fi eld with and without the crop residues and in traffi cked and non-traffi cked areas. Th e CTF system aff ects CO 2 fl ux, the amounts of emissions from the non-traffi cked areas being higher than those from the traffi cked areas. Th e crop residues left on the fi eld cause a decrease of CO 2 fl ux. Th e incorporation of crop residues causes an increase of CO 2 fl ux.
Dubeová M., Gálik R., Mihina Š., Šima T., 2013. Ammonia concentration in farrowing pens with permanent limited range of motion for lactating sows. Res. Agr. Eng., 59 (Special Issue): S9-S14.Livestock production signifi cantly contributes to emissions of polluting gases emissions like ammonia (NH 3 ) and greenhouse gases. Pig production is globally responsible for about 15% of ammonia emissions. Th e aims of this paper were the comparison of the ammonia concentrations in the farrowing pens with permanent limited range of motion between the zones of lactating sows and piglets and the impact of the day hour on ammonia concentration in this place. Photoacoustic infrared measuring devices INNOVA were used.
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.
