Short-term soil carbon dioxide (CO2) emission after application of conventional and reduced tillage for red clover in Western Slovakia
Tillage systems have impact on soil properties, crop growth and through this directly and indirectly influence the cropland CO2 emission and therefore the global warming. In Slovakia, the wider adoption of conservation practices has barriers such as large acreage of compacted soils, the absence of d...

| description | Tillage systems have impact on soil properties, crop growth and through this directly and indirectly influence the cropland CO2 emission and therefore the global warming. In Slovakia, the wider adoption of conservation practices has barriers such as large acreage of compacted soils, the absence of detailed regionalization of suitable soils for such practices and the scientific evaluation of its application on sustainable soil productivity and environment protection. This study evaluated the short-termeffect of conventional tillage (CT) and reduced tillage (RT) with (N1) and without (N0) N fertilizer application on soil CO2 emission from cropland planted with a red clover (Trifoliumpratense) during 40 days in 2013 on a tillage field experiment initiated in 1994. CO2 flux, soil temperature, and soil water contentwere monitored during the studied period in western Slovakia.Results of this study showed that there wasn’t significant difference (p< 0.05) in soil CO2 between conventional tillage and reduced tillage for both, not fertilized and fertilized plots. Averaged 40 days CO2 emissions were greater in reduced tillage as compared to conventional tillage for both fertilization levels. A linear regression between CO2 emission and soil temperature in conventionally and reduced tilled plots showed that soil temperature (r = 0.88-0.94; P <0.05) and not the soil moisture was a controlling factor. The highest CO2 emission were recorded on the CT and RT plots during the first two weeks after tillage, showing that the tillage resulted in a rapid physical release of CO2. |
