“…No Brasil, esse destaque deve ser ainda maior, já que os solos, de maneira geral, são pobres em Zn. Além disso, a disponibilidade de Zn para as plantas pode ser reduzida devido a características do solo, como: pH elevado (Fornes et al, 2009;Lindsay, 1991), altos teores de argila (Shukla & Mittal, 1979), de P (Barrow, 1987;Alloway, 1990), de C orgânico (Mandal & Mandal, 1987;Stevenson, 1991;Uren, 1992), de óxidos de Fe, Al e Mn (McBride, 1989;Stahl & James, 1991) e potencial redox (Gao et al, 2010).…”

“…The positive effect of compost fertilisation can be traced back to the high chelating ability of humic acids derived from compost degradation during the crop cycle. Furthermore, the soil used in our experiment could have emphasised this effect because acidification due to microbial activity increases metal bioavailability in alkaline soil (Santibáñez et al, 2008;Fornes et al, 2009;Fagnano et al, 2011). As regards the T. harzianum A6 effect, both an active uptake by the fungus and an increase in root Cd availability could have contributed to the increase in the rhizome Cd content.…”

“…In some cases, compost fertilisation could be a useful tool to increase metal availability due to the high capacity of metal complexation by humic substances (Clemente and Bernal, 2006;Bianchi et al, 2008), soil fertility due to the soil organic matter buildup (Piccolo et al, 2004;Fagnano et al, 2011), and functional microbial groups (Pepe et al, 2013). Moreover, the effect of exogenous organic matter is pH dependent, allowing an increase in metal availability in alkaline soils (Santibáñez et al, 2008;Fagnano et al, 2011) while this is reduced in low pH soils (Alvarenga et al, 2009;Fornes et al, 2009). Interesting results could also be achieved by modifying the microbe-plant association in rhizo-soil (Cao et al, 2008), since microbes play a key role in soil element cycling.…”

Assisted phytoextraction of heavy metals: compost and Trichoderma effects on giant reed (Arundo donax L.) uptake and soil N-cycle microflora

et al. 2013

Little information is available as to the real effectiveness of the phytoextraction remediation technique, since laboratory experiments are still the most common way in which this is measured. Given this, an experiment on a cadmium-polluted soil was carried out in open field conditions in Southern Italy with the aim of assessing the growth and the phytoextraction potential of giant reed (Arundo donax L). Compost fertilisation and Trichoderma harzianum A6 inoculations were used to verify the possibility of increasing the metal uptake of the crop. Biomass yield of giant reed in the first growth season (average 12.8 Mg ha -1 ) was not affected by the Cd concentration in the soil and this increased significantly with compost fertilisation (13.8 Mg ha -1 ). Both compost fertilisation and T. harzianum inoculation increased cadmium uptake and translocation in leaves. Nitrifying bacteria was shown to be a useful tool to biomonitor soil quality. These results proved the suitability of the giant reed for assisted-phytoremedation with the use of compost fertilisation and T. harzianum. IntroductionThe extent of soil pollution by potentially toxic elements (PTE) in industrialised areas is well documented (Glass, 1998;Black, 1999) and represents an important environmental concern due to their potential accumulation in the food chain. Human activities such as industrial plants, mining, road transport and the unwise application of sewage sludges, fertilisers and pesticides to agricultural soils are recognised to be the main sources of PTE pollution (do Nascimento et al., 2006;Lado et al., 2008). A large number of methods are available to remediate soils, such as soil washing with synthetic surfactants. However, these are extremely expensive, such that a large number of sites remain contaminated (Ensley, 2000). Moreover, ex situ soil reclamation techniques lead to a big reduction in soil fertility due to the soil disturbance and to the toxicity of synthetic surfactants. Soil washing with humic substances extracted from composted organic matter or from geochemical deposits represents a reliable alternative (Conte et al., 2005) and phytoextraction is a valuable complementary technique. It is low cost and environmentally safe (Wu et al., 2006) and is able to both remove heavy metal pollutants from the soil and to offer important economic and agronomic advantages (Mattina et al., 2003). It involves the utilisation of plants to remove heavy metals from soil and concentrate them in the biomass. For years now, metal hyperaccumulating plants such as Alyssum murale, Berkheya coddii, Brassica juncea and Thlaspi caerulescens have been considered the most suitable tool to decontaminate metal-polluted soils, but the low biomass growth and scarce ability to accumulate various different metals together (Krämer, 2005) have discouraged their inclusion in commercial phytoextraction protocols (do Nascimento et al., 2006). Consequently, the current trend is to use fast-growing high biomass crops that accumulate moderate levels of metals in ...

“…Only a few studies have investigated the beneficial effects of fresh OW in restoring crop productivity in degraded soils (Brunetti et al 2005;López-Piñeiro et al 2008;Fornes et al 2009), and even fewer have investigated pesticide behaviour in OW-amended soils (e.g. Albarrán et al 2003;DelgadoMoreno and Peña 2008;Cabrera et al 2009).…”

Influence of two-phase olive mill waste application to soil on terbuthylazine behaviour and persistence under controlled and field conditions

Purpose Terbuthylazine is one of the most common herbicides used to control weeds in olive groves. Application of two-phase olive mill waste (OW) to soils may play a fundamental role in the management of leaching losses of pesticides, especially in Mediterranean areas where soils are characterized by low organic matter levels. We evaluated the impact of OW amendments on the sorption-desorption, degradation, leaching, and persistence of the herbicide terbuthylazine in a representative olive grove soil from Portugal. Materials and methods The soil was amended in the laboratory with OW at the rates of 5% and 10% (w/w), and in the field at the rates of 0.7% and 1.4% of OW for 7 years. Cumulative and residual effects were evaluated in the last year and 2 years after the last OW field application. A batch equilibration method was used to determine terbuthylazine adsorption-desorption. Leaching experiments were studied in hand-packed soil columns. Half-lives (t 1/2 ) were calculated with incubation studies. In the field study, in order to determine the persistence and distribution of terbuthylazine down the soil profiles, at selected times after the herbicide application, soil subsamples were taken from different soil depths. Results and discussion The OW amendments significantly increased the adsorption of terbuthylazine to the soil. Applications of OW to soil significantly reduced the amount of terbuthylazine leached in the field-amended soil columns, with a major residual decrease (from 19.6% to 2.9% at the greater application rate) 2 years after the last OW application. Leaching losses of the herbicide, however, were increased by up to 69.3% for the laboratory-amended soil columns, mainly promoted by an increase in watersoluble organic carbon content. Addition of OW retarded the degradation of terbuthylazine from 6.7 days for the unamended soil to 15.7 and 89 days at the greater application rate in the field-and the laboratory-amended soils, respectively. In the field study, OW addition decreased terbuthylazine's vertical movement through the amended soils with increasing OW rate.Conclusions The study has shown that OW amendment of olive grove soils may be an effective management practice for reducing the vertical movement of terbuthylazine through the soil. However, leaching loss of this pesticide could potentially increase in fresh OW-amended soils, especially if humification of the organic matter is not favoured. In addition, the use of OW could also increase the risk of surface water contamination, especially if application rates are greater than 30 tha −1 .
