Influence of olive mill wastes and thyme oil on some metal sequential extractions in greeenhouse soils

Abstract

The huge amounts of synthetic herbicides are used to control and manage weeds in agricultural soils order to increase the production and efficiency in agriculture. However, the using widespread of synthetic herbicide has been shown to be having potential damages on human health and environment besides resulting in the emergence of herbicide resistant weed biotypes. Besides, the disuse of chemical herbicides in agricultural soils makes the struggle with weeds even harder. It is an urgent need to search for novel compounds, with environmental friendly counterparts in weed control. It is used of essential oils representing allelopathic effects obtained from medicinal and aromatic plants in the fight against weeds and olive mill wastes; with have the phytotoxic and antimicrobial properties as the alternative methods. But the influence of these methods on metal sequential extractions has not been extensively any study so far [1; 2]
