These results indicated that despite differences in plant height and dry matter weight, the corn grown in lead-contaminated soil was similar to that grown in uncontaminated agricultural land. The higher production of dry matter weight by the corn grown in contaminated soil may be the result of the rich nutrients at the site (agricultural activities had been suspended for nearly 10 years). However, because of long-term agricultural production, the uncontaminated agricultural land provided poorer nutrition for crops. Visually, the corn plants appeared strong and had a bright green color because of the good growth conditions in the contaminated soil, indicating that the corn tolerated the lead concentration.
