“…Acacia , furthermore, occurred less frequently, and Hammada and Pelicosepalus acaciae showed a similar tendency. It is unlikely that faster growth is causing this increased size since other scholars have found decreased plant growth resulting from contamination with hydrocarbons (Alkio et al, 2005; Besalatpour et al, 2008; Langer et al, 2010; Pérez‐Hernández et al, 2013). A likely explanation for lower abundance and larger average size is decreased recruitment due to crude oil pollution.…”

Deserts are the most frequent locations of terrestrial crude oil contaminations. Nevertheless, the long-term effects of petroleum hydrocarbons on desert ecosystems are still unknown, which makes risk assessment and decision making concerning remediation difficult. This study examined the long-term effects of petroleum hydrocarbons on perennial desert vegetation. The study site was a hyper-arid area in the south of Israel, which was contaminated by a crude oil spill in 1975. The contaminated area was compared to uncontaminated reference areas. The composition of perennial plants 40 yr after the oil spill was not significantly affected by the contamination. However, the size distribution of the two most dominant shrub species, Baker and (Moq.) Iljin., and the only tree species, Savi and (Forssk.) Hayne, were different from the reference. These differences can be explained by decreased recruitment. The estimated recruitment of in the last 40 yr post oil spill was 74% less than recruitment in the reference area. Low recruitment of may in the future lead to the loss of tree cover, which would change the entire ecosystem, as are keystone species on which a number of microorganisms, plants, and animals rely. Remediation of oil spills and preventative measures are recommended.

“…Roots while growing, release organic material into soil, stabilizing aggregates (Gurska et al, 2009 andTejeda et al, 2013) but salinity by dispersing the aggregates that cause soil structural deterioration (Rengasamy and Olsson, 1991). Soil heterogeneity as an index of texture and structural status that alter mycorrhizal colonization and pollutant distribution in soil so, these can substantially change the plant response and functionality for phytoremediation (Langer et al, 2010;Liu et al 2016). According to Liu et al (2016) sedimentary heterogeneity has a significant effect on hydrocarbon accumulation, which in turn might have similar influences on release and remediation of these compounds.…”

Petroleum and petrochemical hydrocarbons for some places are serious sources of environmental pollutants. To remediate these contaminants, phytoremediation, a relatively low cost and an environmental friendly technique is recommended more widely, now more than ever. Successful and effective applying of hydrocarbons phytoremediation depends mainly on the soil and plant types and conditions and microbial activities and the interactions between these three factors. Although for the last several decades, various plant and organism's species for the phytoremediation processes have been extensively studied, evaluating and characterizing soil properties, as an important objective for sustainable remediation and land use management, which had negligible considerations. An ideal soil for phytoremediation should have proper physical, chemical and biological characteristics to let the plant grow well and produce biomass as high as possible. It also should provide favorable conditions for microbial activities to perform efficient remediation. Soil physical characteristics such as texture, structure, water status and aeration are important factors affecting the microbial activities and consequently the degree of remediation potential. A better understanding of soil physical properties in conjunction with proper soil-plant-microbe management could be exploited to enhance the remediation of hydrocarbon contaminated soils and thus sustainable healthy environment.

The suppressive influence of compost towards the soil-borne fungus Fusarium oxysporum f. sp. lycopersici on tomatoes with special emphasis on root morphological modifications was examined. Roots of inoculated and non-inoculated tomato plants, grown in three different substrates (control, 20 % compost and 40 % compost), were scanned and analyzed in order to identify their morphological traits. To examine a potential systemic effect of compost, the plants were placed in individual pots or in split-root systems. Obtained results showed that F. oxysporum f. sp. lycopersici caused decreased root lengths and reduced root weight, root surface area and root volume. Furthermore, an increase in fine root fraction and specific root length was observed in inoculated plants. Substrate containing 20 % compost had a clear stabilizing effect towards pathogenrelated changes of the root morphology and was best able to mitigate below-ground symptoms on plants cultivated in individual pots. The morphology of roots grown in split-root systems was not directly affected by the presence of F. oxysporum f. sp. lycopersici, but complex interactions between the pathogen and the substrate were observed, strongly depending on which substrate was inoculated. These results indicated that soil amendment with compost in moderate amounts contributes to plant health and could provide an alternative to peat based substrates in sustainable production systems.
