Plant and microbial establishment in pesticide-contaminated soil amended with compost
1994

Pesticide-contaminated soil (obtained from an agrichemical retail facility) was mixed with uncontaminated soil or with compost to determine the impact of compost compared to soil on plant establishment and growth, rhizosphere populations, and development of soil microbial populations and activity. Plants were established and grew well in pesticide-containing soil when consideration was given to compatibility between plant herbicide tolerance and the specific herbicide(s) present. Rhizosphere fungal and bacterial populations developed to a range of 100,000 to several billion units get root, respectively. Soil bacterial populations were significantly higher in compost-containing mixes when compared to contaminated soil alone, while populations in soil mixes were not affected by any treatment. Fungal populations were significantly higher in planted mixes and in unplanted mixes with compost than they were in contaminated soil alone. Dehydrogenase activity was significantly higher in compost-containing mixes than in soil mixes.
