EFFECT OF SOME INDUSTRIAL WASTES OF 10th OF RAMADAN CITY ON SOIL AND PLANT

Abstract

The objective of this work was to study the effect of using solid and liquid industrial wastes on soil and plant composition under greenhouse experiments. In two experiments faba bean or com grown on lOth ofRamadan and Ras Sudr soils were treated with soil and liquid dying, ceramic, paper and starch industrial effiuent wastes. Also their dilution or mixture were studied.

Results showed. that . the irrigation with industrial waste increased soil ECpH_and O.M. The highest increases of pH and EC were found with applying liquid ceramic waste and the lowest values were with starch eftluent waste, while the highest increase of soil 0.M. was found with starch waste.

Soil total and available macro-micro and heavy­ elements and their contents in pOiatns increased differently with industrial wastes application. The highest increases of N, P, K Ca and Mg were found with starch effiuent irrigation. Paper effluent waste irrigation treatments resulted in remarkable increases of Fe, Mn, Zn, Cu, Pb, Cd, Co and Ni in soils and plants. Particularly chemically available Cd and Co in the soil increased about 50 folds and their concentrations in plant increased about 4 folds.
