Leta 2013 je bil izveden poljski poskus v bližini Zg. Kungote, pri katerem smo primerjali pojavnost izpustov CO2 iz težkih tal zaradi različnih tehnik obdelave tal oranje in priprava tal s predsetvenikom, rahljalnik in direktna setev. Ugotoviti smo želeli vplive različnih načinov obdelave tal in vremenskih dejavnikov na mesečno velikost izpustov CO2. Pri obdelavi s pomočjo pluga se je v mesecu maju pri povprečni temperaturi 14,77 °C in 35,2 mm padavin povprečno sprostilo 26,16 μmol/m2s. Pri konzervirajoči obdelavi smo največjo vrednost izpustov CO2 (9,0 μmol/m2s) izmerili v mesecu septembru, pri povprečni temperaturi 14,92 °C in 143,6 mm padavin. Prav tako smo meseca septembra zabeležili največje izpuste CO2 pri direktni setvi (11,00 μmol/m2s). Povprečne letne vrednosti izpustov CO2 so znašale pri konzervirajoči obdelavi 4,90 μmol/m2s, pri direktni setvi 5,40 μmol/m2s in pri obdelavi s plugom 8,0 μmol/m2s, kar pomeni, da lahko z izbiro različnih načinov obdelave tal pomembno vplivamo na zmanjšanje izpustov CO2 pri poljedelstvu. In year 2013 field trial near Zg. Kungota was conducted. We compared the incidence of CO2 emission from heavy soil by various techniques of soil tillage ploughing, tilling, scarification and direct sowing. We wanted to determine the impact of different ways of processing the soil and climatic factors on the amount of monthly CO2 emissions. When tilling using the plow in the month of May with an average temperature of 14.77°C and 35.2 mm of precipitation the average emission of CO2 was 26,16 mol/m2s. Where we used conservation tillage the maximum value of CO2 emissions (9,0 mol/m2s) were measured in the month of September with an average temperature of 14,92°C and 143 mm of precipitation. In September we also recorded maximum value of CO2 in soil cultivated by direct sowing (11, mol/m2s). The average annual values of CO2 emission were: 4,9 mol/m2s at the soil cultivated by conservation tillage, 5,4 mol/m2s by direct sowing, and at the soilcultivated by plow 8,2 mol/m2s. This means that we can significantly influence on the reduction of CO2 emissions from agriculture with various different soil treatments

Leta 2012 je bil izveden poljski poskus na lokaciji Podova v občini Rače-Fram, v kraju Gorica ob glavni cesti. V poskusu smo primerjali pojavnost izpustov ogljikovega dioksida iz lahkih tal med tremi tehnikami obdelave tal oranje in priprava tal s predsetvenikom, rahljalnikom ter direktna setev. Namen poskusa je bil ugotoviti, kateri načini obdelave tal povzroča večje izpuste ogljikovega dioksida iz tal in ali so izpusti ogljikovega dioksida odvisni od temperature tal in padavin. Iz pridobljenih rezultatov smo ugotovili, da je najprimernejši način obdelave tal neposredna oziroma direktna setev. Ta način obdelave v primerjavi z drugima dvema načinoma ne prihrani le časa in energije za obdelavo, ampak tudi v veliki meri zmanjšuje izpuste CO2 iz tal, ne glede na količino padavin in temperaturo. Sledi ji konzervirajoča obdelava tal, ki izboljšuje vse lastnosti konvencionalne obdelave tal. Povprečni letni izpusti so se zvišali pri oranju 4,71 μmol/m2 s, pri rahljanju 4,53 μmol/m2 s in pri direktni setvi 2,70 μmol/m2 s. In 2012 a field experiment was carried out in Podova, the Rače-Fram district, in the village of Gorica. In this experiment we compared the occurrence of CO2 emissions from the light soil when three soil techniques were applied: ploughing with mouldboard plough and soil preparation with cultivator, chisel plough and direct sowing. The intention of the field trial was to find out, which type of soil treatment causes greater CO2 emissions and whether these emissions depend also on the soil temperature and precipitation. We found out that the most suitable soil treatment is direct sowing with the average yearly amount of 2.70 μmol/m2 CO2 emissions. This treatment, compared to the other two, not only saves time and energy but also decreases CO2 emissions, regardless of temperature and precipitation. This technique is followed by the preserving soil treatment with chisel plough with the average yearly amount of 4.53 μmol/m2 CO2 emissions, which improves all soil characteristics. The average yearly emissions have risen in ploughing in which the average yearly amount of 4.71 μmol/m2 s CO2 emissions was measured.
