“…In a previous work conducted by Benintende et al (2008), they pointed out that MBC, MBN, and PNM-AI behaved as good soil quality indicators. Variability found in our study for MBC, MBN, and PNM-AI variables was greater for spring sampling time compared to autumn.…”

“…2), based on results reported by Benintende et al (2008), who found these were sensitive to measure crop rotation effects on soils as well as other management practices (Bending et al, 2004;Marinari et al, 2006;Monokrousos et al, 2006).…”

“…Soil biological indicators are often assumed to be good soil quality indicators due to their high sensitivity and ability to reflect soil management effects (Marinari et al, 2006;Benintende et al, 2008;Kaschuk et al, 2011). However, biological properties frequently show high temporal variability (Tscherko and Kandeler, 1999;PazFerreiro et al, 2013).…”

“…A brief description of the above-mentioned indices is necessary: diversity and the activities of microbial communities are key factors in the evaluation of the quality of soil and in many cases may be used to alter the composition of microbial communities, as well as being an easily accessible, and sensitive indicator, of anthropogenic effects on soil ecology (Benintende et al 2008;Wang et al 2007). Soil respiration remains one of the most recognized and still most commonly used parameters for the quantification of soil microbial activity (Jesußek et al 2013;Kieft and Rosacker 1991;Yang et al 2014).…”

Compositional and metabolic quotient analysis of heavy metal contaminated soil after electroremediation

Heavy metal soil contamination provides a danger both to human and environmental ecosystem health and is still on the rise in many developing countries. Electroremediation provides an innovative method to remedy contamination of soils by heavy metals. Fundamental to the acceptance of any soil remedial technique is proof that positive benefits outweigh the negative impacts, in terms of soil health. The environmental effect of electroremediation of heavy metals contaminated soil by some biological indicators was evaluated. A soil contaminated with Zn, Pb, Ni, and Cd was used in a laboratory experiment. Treatment was imposed with a constant voltage gradient of 0.83 V/cm for 20 days. Results indicated that the physicochemical changes caused by the electroremidiation process on the soil microbial population (actinomycetes and gram-positive and negative bacteria), soil respiration and microbial biomass were significant (p \ 0.01). At the commencement of the study, soil microbial activity was reduced, due to physicochemical changes in pH, amount of moisture and the changes in the levels of heavy metals in the soil. The greatest reduction on the microbial activity was close to the cathode where high levels of heavy metal concentrations and high pH were demonstrated. The metabolic quotient index [qCO 2 ] was used to achieve a more refined evaluation, compared to analysis of soil respiration and microbial biomass alone. Accordingly, high amounts of qCO 2 near the cathode show the unfavorable living conditions of such microorganisms in these sections.

“…Soil quality is defined as the potential of a soil to function within ecosystem boundaries to maintain biological productivity, sustain environmental quality and promote plant health (Doran & Parkin 1994). Both chemical and microbiological parameters could be used as soil quality indicators (Benintende et al 2008). In general, most soil chemical parameters respond slowly to changes in land use, and long years are required to obtain a significant difference between treatments (Lagomarsino et al 2009 changes in soil management (Kennedy & Smith 1995).…”

Soil chemical and microbial parameters are commonly used as soil quality indicators to evaluate sustainable land management in agroecosystems. The objective of this research was to evaluate the impact of organic and conventional management strategies on biological, chemical and yield parameters in vineyards (Vitis vinifera cv. Sultani seedless). Organic plots received a mixture of barley, vetch and broad bean (25 þ 35 þ 75 kg seed ha 21) as green manure, and farmyard manure (15 t ha 21 ) every year. Inorganic fertilizers (NPK) and pesticides were used in the conventional managed vineyards. Conventional and mulch tillage methods were used in conventional and organic plots, respectively. Microbiological and chemical soil properties were determined in the soil samples which were taken four times in 2004, 2005, 2006 and 2007. In addition, the yield and some quality parameters of vineyards were also determined. Soil microbial biomass, and dehydrogenase, b-glucosidase and alkaline phosphatase activity were significantly higher in organic management than in conventional management. Higher C mic /C org and lower qCO 2 values were found with the organic management. The response of the chemical indicators (C org , N t and available nutrient content) of the soils to different management systems appeared after a longer time than with the biological indicators. In the transition zone between continental and Mediterranean climates of West Turkey, soil quality of organically managed vineyards improved after 2 years of the transition period prescribed for organic certification. However, soil quality improvements in organic plots did not result in higher yield.
