Electrical conductivity followed a similar pattern as pH. EC value decreased in the contaminated soil on introduction of compost by 6% in ‘compost-only’ treated soil and 15% in ‘compost + Kenaf ’ treatment. This revealed the positive impact of compost on contaminated soil EC. High EC can affect the microbial activities in soil[34]. Smith and Doran [35] demonstrated that the yield of certain crops (barley, cotton, sugar beet and wheat) decreased as EC value of soil increased beyond the threshold limit. EC of the compost is lower than the threshold limit of 4000 S cm−1, which may be toxic to plant [36].
