It was observed in the three soils used in this study that shoots, roots and whole plant dry weight of Zea mays significantly increased as a result of compost application compared to without compost application. With the three soils used in the study, results showed that plants grown in soils amended with compost and supplied with rock phosphate (RP) at the highest phosphate level recorded the highest shoots, roots and whole plant dry weight compared to those supplied with single super phosphate (SSP). Cadmium, lead and zinc contents of shoots & roots of zea mays plants were significantly reduced as a result of compost application compared to without compost application. Rock phosphate addition significantly reduced Cd, Pb and Zn contents of shoots and roots of zea mays plants compared to single supper phosphate for the three soils used Issued also as CD Compost and phosphate application Contaminated soil Heavy metals Mona Fawzy Abdeghany , Supervisor Youssief Ali Abdelaal, Supervisor http://172.23.153.220/th.pdf Nazla Revisor Shimaa Cataloger ddc TH 73814 73814 ddc 0 CUCL cl210 2024-02-11 Cai01.07.18.M.Sc.2019.He.E 01010110079207000 2023-09-22 00:00:00 TH ddc 0 CUCL cl2u8 2024-02-11 Cai01.07.18.M.Sc.2019.He.E 01020110079207000 2023-09-22 00:00:00 79207.CD CD
