e2“to irrigate winter wheat and summer maize with annual double cropping system in the North China Plain (NCP)”
e1“The electrical conductivity of the saturated soil extract (ECe), soil pH, sodium adsorption ratio, and bulk density within the top soil layer of 030 cm increased with the increase in ECiw, whereas the soil organic carbon, porosity, macroaggregates (> 0.25 mm) content, and activities of catalase, urease and alkaline phosphatase decreased”

Other claims from this paper (10)
- Intervention effect Saline water with ECiw at 3.4 dS·m−1 gave no significant difference in grain yields compared with the CK treatment.
- Intervention effect Soil salinity in the 0-100 cm layer could be kept at a low level with saline water at ECiw 3.4 dS·m−1.
- Observation Soil salt accumulated in winter wheat seasons could be leached from the main root zone in the following summer maize seasons.
- Intervention effect The difference in soil properties between ECiw 3.4 dS·m−1 and the CK treatment was not apparent.
- Association Electrical conductivity of the saturated soil extract, soil pH and sodium adsorption ratio in the top 0-30 cm layer increased with ECiw.
- Association Bulk density in the top 0-30 cm layer increased with ECiw.
- Association Soil organic carbon, porosity and macroaggregates content in the top 0-30 cm layer decreased with ECiw.
- Intervention effect Relative grain yields were reduced by below 5% with ECiw lower than 3.17 dS·m−1 compared with CK.
- Intervention effect Soil quality index was reduced by below 5% with ECiw lower than 3.10 dS·m−1 compared with CK.
- Recommendation ECiw of 3.10 dS·m−1 is recommended as the safe utilization threshold for long-term saline water irrigation in the NCP.
