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