Mobility and leaching of heavy metal through soil layers as affected by the application of different levels of Cd, Ni and Pb on corn plants [electronic resource].

Includes reference.

A laboratory experiment was designed to study the mobility of heavy metals through soil layers by corn plants. This experiment were conducted at the National Research Center (NRC) in order to satisfy the objectives of the current investigation. The obtained results can be summarized as follows: 1. The application ofNPK fertilizers increased the fresh and dry weight of corn plants as compared with the application of heavy metals. 2. The small additions of heavy metals (H.M) with NPK fertilizers resulted in an increase in the dry matter production of corn shoots. By increasing the added amounts of Cd, Ni and Pb, the dry matter production decreased, and it was the lowest in the heavy metal treatment as the recorded reductions were obtained with 150 ppm, 100 ppm and 50 ppm, respectively.
