CO<sub>2</sub> emissions in a soil under different tillage practices

CO2 emissions represent one of the greenhouse gases significantly affecting climate change. Reduced tillage practices can contribute to mitigation from soils. The effect with different straw incorporation on was studied in field experiments years 2020 and 2021. winter wheat used 2020, spring barley Treatments were: (1) chiselling 10–12 cm; (2) shallow (5–6 cm depth); (3) mulch, (4) stubble. warm summer period increased soils even twice comparison other soil practices. temperature decreased following order: < ≤ stubble mulch 2020. Low without significant differences among treatments were observed year 2021 when low temperatures excessive water content filling pores caused by intensive precipitations (23 mm) coming shortly after observed. are affected a number factors. Among them current weather conditions as well depth handling postharvest residues, important.
