“…It is well known that the decomposition of organic substances increases soil acidity (Vaseghi et al, 2005). Under intensive tillage, the O 2 level of soil increase and suitable environment is provided for microbial activities, thus CO 2 emission increase (Yerli et al, 2022). The results of daily CO 2 emission from levels of the factors are shown in Fig.…”

“…The decomposition of organic matter and carbon release is an aerobic process in which oxygen increases the activity of microbes that feed on organic matter. One of the soil properties that has signi cant effect on CO 2 emission from residue is soil pH (Yerli et al, 2022). It is reported that the lowest and highest CO 2 emission occurs in strongly acidic soils and slightly acidic soils (Ntonta et al, 2022).…”

In this study, the amounts of greenhouse gas (equivalent to CO2) emitted from inputs consumption and CO2 emission from the soil in the various wheat-maize farming systems for one year were evaluated in an experimental design. In the studied systems, the CO2 eq emission from the inputs for wheat and maize ranged from 258 to 365 kg.ton− 1 and 140 to 313 kg.ton− 1 respectively, which electricity, fertilizer and fuel inputs had the largest share. By changing the agricultural systems, there was a potential to reduce CO2 eq emission from the inputs by up to 29% per ton of wheat and up to 55% per ton of maize. Results showed that residue management, irrigation method, and tillage had significant effects on CO2 emission from the soil, while planting method showed no significant effect. Systems with residue (R1) had about 28% higher CO2 emission from the soil, by changing the tillage method from conventional tillage (T1) to no-tillage (T3) and changing the irrigation method from flood (I1) to drip (I2), a reduction of approximately 20 and 12% in emission was observed, respectively. Among the studied systems, the highest amount of CO2 emission from the soil was observed in the system with residue, conventional tillage, flood irrigation, and flat planting (R1T1I1P1) with a rate of 7.35 kg.ha− 1 per day. The highest total CO2 emission from inputs and emission from the soil were observed in R1T1I1P1 system with a rate of 6129.47 kg.ha− 1 per year, which decreased to 4471.28 kg.ha− 1 per year in R2T3I2P2 system.

“…This might contribute to the benefit of irrigation cooling. Water application can decrease the soil temperature and create a cooling effect on the soil by increasing the soil moisture [47,48]. In the Jing-Jin-Ji region, most cities belong to areas with high effective irrigation rates.…”

Effects of Meteorological Conditions and Irrigation Levels during Different Growth Stages on Maize Yield in the Jing-Jin-Ji Region

Maize is a major crop that is particularly sensitive to climate change. In addition, the extreme shortage of water resources threatens crop production. Thus, improving the effective utilization rate of water is an important problem to discuss. In this regard, we quantified the combined effects of meteorological conditions and irrigation levels during different growth stages on city-level maize yields in the Jing-Jin-Ji region from 1993 to 2019. The results show that the sowing period was affected by the minimum temperature, while the other growth stages were affected by the maximum temperature. At the ear stage of summer maize, when the effective irrigation rate reached the average level (52%), the inflection point of the total precipitation was 401.42 mm in the Jing-Jin-Ji region. When the total precipitation was higher than 401.42 mm, the summer maize yield decreased with the increasing total precipitation. Furthermore, the summer maize growth was significantly affected by drought at the seedling stage. At high effective irrigation rates and over long dry spells, as the mean daily temperature during dry spells increased, the maize yield easily increased. The increase in the effective irrigation rate can reverse the decrease in the summer maize yield. Moreover, the effective irrigation rate increased the maize yield with the increase rise in the temperature during longer dry spells, but the maize yield decreased with warmer temperatures during shorter dry spells. As such, our evaluation results will be useful for assessing food security and moving gradually toward achieving a water–energy–food nexus.

“…Irrigation with treated wastewater provides higher yield, especially in arid and semi-arid regions, and also provides the opportunity to grow crops with high economic value (Qadir et al, 2015). Wastewaters are separated from other waters due to their rich organic matter, nitrogen, phosphorus, and potassium contents, and with these aspects, they increase soil and crop productivity with their use in irrigation (Becerra-Castro et al, 2015;Rivas et al, 2017;Yerli et al, 2022). In addition, considering the heavy metal and pathogen risks in the use of wastewater in irrigation, it is of great importance to carry out irrigations (Dogan Demir and Sahin, 2017;Demir, 2021).…”

Increasing pressure on water resources in the world has revealed the necessity of using marginal water resources in irrigation. With the use of wastewater, which is one of the marginal water resources, the pressure on freshwater resources is alleviated, the discharge problems of wastewater are solved, and soil and crop productivity increase with the high nutritive effect of wastewater. However, salinity, heavy metals, some harmful chemicals, and the pathogen risks of wastewater should not be ignored. In this context, in this study, the effluent of the wastewater treatment plant located in the central Edremit district of Van province was evaluated in terms of usability in irrigation. Samples were taken from treated wastewater during the vegetation period in 2020 and 2021 and pH, EC, cation and anions, micro elements and heavy metal, total nitrogen and phosphorus, total suspended solids, chemical oxygen demand, biological oxygen demand, fecal coliform, percent sodium, sodium adsorption rate, residual sodium carbonate and Langelier saturation index were determined by analysis and calculations. As a result of the study, the treated wastewater does not pose a risk in terms of pH, EC, cation and anions, micro elements and heavy metal, total suspended solids, percent sodium, sodium adsorption rate, residual sodium carbonate, langelier saturation index and fecal coliform, but attention should be paid to the total nitrogen and phosphorus, chemical and biological oxygen demand contents. It was concluded that the treated wastewater is in compliance with national and international standards, and there is no harm in its use in irrigation and thus treated wastewater can be recommended as a reliable water source for irrigation in the semi-arid province of Van/Edremit. However, in order to ensure safe and sustainable management in irrigation with wastewater, it is necessary to monitor water quality and make necessary inspections of soil, crop and irrigation systems.
