Effect of water and fertilization management on Cd immobilization and bioavailability in Cd-polluted paddy soil

The field trial was conducted to investigate remediation effects of two alkaline fertilizers and three water management techniques on Cd contaminated paddy soil. The results revealed downward trend of soil pH and EC during growth period of rice. The treatment of organic fertilizer has indicated high pH and organic matter than treatment of calcium magnesium phosphate fertilizer. The integrated effect of organic fertilizer and continuous flooding (COF) has significantly (p
