Abstract
(I) The present work aimed to evaluate the effect of lead and traffic exhausts pollution on growth of some economic plants beside the effect of rhizobial inoculation and some soil amendments as protective agents against lead pollution were studied. The following variances were dete~mined; plant growth, yield components, chemical composition and the population of beneficial microorganisms living in the nonrhzosphere soil of these plants. (2) To acheve the objectives of this study, three separate experiments were
conducted. The first experiment was conducted along two different motorways, the fxst one is Cairo-Alexandria agricultural road at Berket El-Sabaa location, and the other one is Tanta-Kafi El-Sheikh road at Smella location. The plant species studied in this experiment were faba bean, clover, maize and wheat. Both roads are characterized by traffic densities averaged 37000 and 13000 cadday, respectively. The experimental soil and plant samples were collected at harvesting in three spots i.e. 10, 70 and 150 m far from the road and the latter was considered as control. (3) The second experiment was canied out in pots in a wire proof green house at Sakha Agricultural Research Station to evaluate the possible role of phosphoms (calcium super phosphate); calcium (agricultural gypsum); organic matter (farmyard manure); and their combinations as different soil amendments, for decreasing lead absorption by faba bean. Faba bean plants variety Giza 3 were grown in soil treated individually or in combinations with the above-mentioned soil amendments at the following levels: (1) 200, 300 and 400 Kglfed, super phosphate; (2) 5, 10.0, and 20 todfed farmyard manure; (3) 3, 4.5 and 6.0 ton / fed. agricultural gypsum and (4) the dual and trio combinations of these amendments. The experimental plant and soil samples were collected at the corresponding harvest time.
