The use of recycled wastewater in agricultural irrigation
contributes to ecosystem by reducing the discharge of wastewater to the
environment, as well as increasing soil quality with fertilizing effect.
However, since the high nutrient of wastewater can make the soil a source of CO2
emission, it is necessary to know the relationships between CO2
emission and soil properties to the management of emissions. This study aimed
to determine the relationships between CO2 emission and soil
properties by examining the changes in the properties of soil irrigated with
recycled wastewater and freshwater at different levels. The results showed that the recycled wastewater caused 58.1% more CO2
emissions than freshwater in full irrigation treatments, while the emissions
decreased in the range of 8.8% to 44.5% with increased deficit irrigation. In
addition, the significant relationships of CO2 emission with EC, pH,
CaCO3, organic matter, total N, P2O5, K2O,
cation exchange capacity, porosity, aggregate stability properties of the soil
and H2O emission from the soil, soil moisture and temperature at
different depths were determined, demonstrated the effectiveness of these
parameters in the management of CO2 emissions in soil irrigated with
recycled wastewater. Considering the obtained findings, it was determined that
deficit irrigation is very effective in reducing CO2 emission and
considering the effectiveness of soil temperature and soil properties on the
emissions, CO2 emission can be reduced by soil temperature and soil
properties management, and more comprehensive studies on this subject could
suggest.
