The Optimal Root Length for Vetiveria zizanioides When Transplanted to Cd Polluted Soil.

Evaluation of Mobility, Bioavailability and Toxicity of Pb and Cd in Contaminated Soil Using TCLP, BCR and Earthworms

The objective of the present study was to investigate the reduction of mobility, availability and toxicity found in soil contaminated with lead (Pb) and cadmium (Cd) from Santo Amaro Municipality, Bahia, Brazil using two combined methods, commonly tested separately according to the literature: metal mobilization with phosphates and phytoextraction. The strategy applied was the treatment with tw...

Highly volatile constituents of Vetiveria zizanioides roots grown under different cultivation conditions.

Roots of Vetiveria zizanioides Nash (Mae Hae; Thai ecotype) planted in three different cultivation systems (normal soil, normal soil with added microbes and semi- hydroponically) were extracted using a simultaneous steam distillation and solvent extraction (SDE) apparatus. Yields of the essential oils obtained were 0.27, 0.18 and 0.06%, respectively. The separation profiles obtained by comprehe...

بررسی گیاه پالائی خاک های آلوده به سیانید با استفاده از گیاه وتیوریا زیزانیاوایدس (Vetiveria zizanioides)

Background and Objective: In the field of environmental risk assessment, Cyanide is one of the most important pollutants of water, soil and air that has an important impact on the ecosystem and environment of the contaminated area. Therefore, the present study aimed to prove the biological effectiveness of Vetiveria zizanioides in phytoremediation of soils contaminated with cyanide. Materials ...

Investigation on the Effects of Eco-cover on Unwanted Plant Control, Vetiver Grass (Vetiveria zizanioides) Growth and Soil Properties

Eco-cover is ecological mulch and its application is an eco-friendly and low-cost method to improve soil environment and prevention of unwanted plants. The aim of this study was to investigate the effects of eco-cover on unwanted plants, Vetiver grass (Chrysopogon zizanioides) growth and soil Properties. For this purpose, two series of rectangular plot (with and without eco-cover), in three rep...
