Quality of different water sources for the experiment.
Water Source | EC | pH | Na+ | K+ | HCO3− | Cl− | Ca2+ | Mg2+ | SO42− | SAR | TN | TP | Pb | Cu | Zn | Cd |
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
FW | 0.321 | 8.31 | 0.4 | 0.04 | 1.96 | 0.85 | 0.98 | 0.61 | 1.08 | 0.34 | 1.17 | 0.02 | ND | ND | ND | ND |
RW | 2.120 | 8.17 | 13.5 | 0.36 | 4.56 | 8.85 | 2.28 | 3.10 | 5.28 | 5.81 | 0.52 | 0.05 | ND | ND | ND | ND |
BW | 6.100 | 8.41 | 57.8 | 0.05 | 2.32 | 54.20 | 1.08 | 0.71 | 0.96 | 43.21 | 1.31 | 0.02 | ND | ND | ND | ND |
Note: EC represents electrical conductivity, dS m−1; SAR represents sodium adsorption ratio, (mmol L−1)0.5; TN represents total nitrogen content, mg L−1; TP represents total phosphorus content, mg L−1; Pb, Cu, Zn, Cd, the unit is mg L−1; Na+, K+, HCO3−, Cl−, Ca2+, Mg2+, SO42−, the unit is mmol L−1; ND indicates no detected: concentration were below the instrumental detection limit.
