Abstract
The effect of chemical effluents discharged from a chemical and fertilizer factory on physicochemical properties of soil and germination and mineral composition of wheat was studied at Varanasi, India. Forty times higher concentration of Na was observed in the effluent than that of the nearby well water. It showed a positive (significant) correlation with Na and a negative (significant) with K and Ca of the soil. Cation exchange capacity (CEC), porosity and water holding capacity were reduced by effluent affected soil. the germination percentage of wheat was negatively correlated with the Na of effluent and Na+Mg/Ca of the soil. A significant (positive) correlation existed between Na of effluent and Na content of the plants. Calcium percentage on the other hand, exhibited a reverse trend.
