Changes in soil chemical properties as affected by application of wastewater spiked with heavy metals

Wastewater was spiked with cadmium (Cd), chromium (Cr), nickel (Ni) and lead (Pb) at various concentrations applied in soil under gladiolus crop research farm of Water Technology Center, ICAR-IARI, New Delhi during 2017. Changes parameters were determined as per the standard methods. Results indicated that properties in-terms pH, organic carbon, phosphorous, potassium micronutrients (Cu, Fe, Mn, Zn) not changed significantly, whereas significantly higher salt (EC 0.41 dS/m), nitrogen (161.50 kg/ha) well Ni (0.75 mg/kg), Cr (1.64 Cd (0.17 mg/kg) Pb (2.75 T5 treated soils recorded, where highest concentration metals, i.e. (0.5 mg/L), (5.0 mg/ L), (10 (50 mg/L) wastewater. It may be concluded application metals wastewater irrigation alter functioning by way elevated levels metal pot experiment.
