“…While lead and cadmium contents in soils K2 and P2 were comparable, zinc in soil K2 exceeded its content in soil P2 about three times. Zinc is considered as one of the most toxic elements to microbial biomass (Chander and Brookes 1993, 1995, Brookes 1995, Leita et al 1995, Nannipieri et al 1997, Ledin et al 1999) whereas low toxicity is reported for lead, the main polluting element in Příbram soils (Bajaras-Aceves et al 1999). The higher content of microbial biomass in contaminated soil P2 obtained during incubation with glucose could result from lower carbon consumption by the microbial pool in the more contaminated soil.…”

A laboratory incubation experiment with zeolite and glucose was performed to evaluate the effects of zeolite amendment in heavy metal contaminated soils from two smelter areas on some microbial characteristics [Kremikovtzi (K1, K2) in Bulgaria and Příbram (P1, P2) in the Czech Republic]. The content of microbial biomass showed a tendency to decrease in Kremikovtzi soils whereas in Příbram soils no significant effects were found after zeolite amendment. Respiratory activity and metabolic quotient (qCO 2 ) decreased on the second and third day in Kremikovtzi soils amended with zeolite, no effects were observed in Příbram soils. Heavy metals decreased the content of microbial biomass in Kremikovtzi soils whereas the contaminated soil from Příbram area had the highest microbial biomass compared to non-contaminated soil during incubation, probably due to lower mineralization of carbon. The respiratory activity did not show any significant effects of zeolites on the evolution of CO 2 and qCO 2 in heavy metal contaminated Příbram soil. The respiratory activity in non-contaminated Příbram soil remained during the experiment lower in comparison to contaminated one, however the addition of zeolite increased qCO 2 .

“…For the reason specified, the research that has been conducted ranges from the impact of heavy-metal contamination on microbial biomass and activity (Angle et al, 1993;Brendecke et al, 1993;Chander & Brookes, 1993;Yeates et al, 1994;Speir et al, 1995;Valsecchi et al, 1995;Frostegård et al, 1996) to the responses of soil microbial organisms to pesticides (Harden et al, 1993) and industrially contaminated soils (Rowell & Florence, 1993). Key processes and components are used mainly to formulate measures that are symptomatic of disease.…”

Soil is a non-renewable resource and supports all land-based forms of life. The sustainable production of crops is becoming progressively more critical as human populations increase and viable agricultural land decreases. Soil health plays an indispensable part in the sustainability of soil as a resource for future generations. For this very reason it is important to have suitable tools to measure the improvement or deterioration of soil health in vineyards and orchards. In this review, the use of different bio-indicators to indicate soil health will be discussed, with special emphasis on the use of nematode population structure and function as indicators of soil health. The use of nematodes as a bio-indicator of soil health can play a crucial role in the establishment of future sustainable production of grapes and fruit in the Western Cape. This paper provides a comprehensive review of soil health, the use of different biological indicators, and the potential of nematodes as suitable indicators thereof, aimed at vineyards and deciduous fruit orchards.

“…Treatments A to D resulted in some decrease in C mic when compared with Treatment E (no mine tailings). Chander and Brookes (1993) reported that high concentrations of heavy metals decreased the functional diversity of the soil microbial community, affected the soil microbial population, and weakened the microbial activities. The soil microorganisms reacted to heavy metal pollution by losing their original ecological function, resulting in a reduction in soil environmental quality.…”

Tolerance of Grasses to Heavy Metals and Microbial Functional Diversity in Soils Contaminated with Copper Mine Tailings

et al. 2008

Copper (Cu) mine tailings, because of their high content of heavy metals, are usually hostile to plant colonization. A pot experiment was conducted to determine the tolerance of four forage grasses to heavy metals in Cu mine tailings and to examine the variation in the microbial functional diversity of soils from the tailing sites in southern China. All the four grass species survived on Cu mine tailings and Cu mine tailing-soil mixture. However, on pure mine tailings, the growth was minimal, whereas the growth was maximum for the control without mine tailings. The tolerance of grasses to heavy metals followed the sequence: Paspalum notatum > Festuca arundinacea > Lolium perenne > Cynodon dactylon. The planting of forage grasses enhanced the soil microbial biomass. The Biolog data indicated that the soil microbial metabolic profile values (average well color development, community richness, and Shannon index) of the four forage grasses also followed the sequence: P. notatum > F. arundinacea > L. perenne > C. dactylon. Thus, P. notatum, under the experimental conditions of this study, may be considered as the preferred plant species for revegetation of Cu mine tailing areas.
