EFFECT OF TILLAGE SYSTEMS AND SOIL MICROBES ON CONCENTRATION OF SOME AVAILABLE SOIL HEAVY METALS AND CROP YIELD
The main object of this study is to investigate the influence of adding different soil microorganisms under different tillage systems on concentration of some heavy metals and productivity of crop yield. The experiments were carried out in clay soil during four successive seasons in private farm at Abo-Dawood village, Dakahlia governorate. The experimental field located far from contamination sources such as roads, factories or large cities.
The obtained results indicated that the conservation tillage system increased the crop yield about 50%, 37.5% in second season and 44.4%, 39.3% in fourth season in comparison with conventional and intensive tillage systems respectively. addition of Bucills megaterium led to an increase in the wheat crop yield in all tillage treatments with an increase by 20.4%, 18.6% and 19.8% as well as adding Cyan bacteria led to an increase in the productivity of the wheat crop with an increase by 12.3%, 10.9% and 7.8% in conventional, intensive and conservation tillage treatment respectively.
