Abstrakt: This article discusses how organic amendments change soil microbial biomass and improve soil health in an agricultural soil contaminated by zinc and lead. Two organic amendments were added to the soil (cow manure and olive husk) to reduce heavy metal solubility and improve fertility. Two successive crops of Beta species (Beta vulgaris and Beta maritime) were grown on treated and untreated plots. According to the authors, results indicated that heavy metal stress on the microbial population was reduced by the amendments, showing a beneficial effect on fertility and soil quality.
