“…2). This was observed by Van Herwijnen et al [29] , attributing these results to the degradation in the time of organic matter contained into compost; reason why trace elements adsorbed in it was released to bioavailability forms. In our study we could realize the same reasoning due to the increase in microbial activity.…”

Problem Statement:The anthropogenic activities can cause adverse effects in soils, increasing in some situations trace elements contents, impacting negatively both the microbial biomass and activity. Among the practices used for the recovery of soil quality we can find the application of organic amendments or the product of their composting. These can adsorb trace elements decreasing their availability and increasing the soil microbial biomass. The microorganisms of the soil use to be considered as sensitive biological indicators of the changes produced in the soil quality. Approach: One processes to quantify soil biological activity is the respiration. The aim was to evaluate the effects of two organic amendments application on soil microbial activity, in a soil contaminated with copper (Cu), zinc (Zn) and chromium (Cr). To prove the raised aim we quantified CO 2 -C release. Results:The results showed that at the end of the incubation period, as much in contaminated soils as in soils without contamination, the total activity of microorganisms was significantly increased by the application of organic amendments (p = 0.0062 and p = 0.0005, respectively). The application of both composts to slightly acid soils increased the initial and final values of pH. There was no evidence of modification in Electrical Conductivity (EC) because of compost application. At the end of the incubation period a negative relationship was observed between EC and CO 2 -C (R 2 = 0.74, p = 0.0028). Conclusions: The obtained results in this study suggested that it was possible to increase the total activity of soil microorganisms and to reduce the bioavailability of Cu, Cr and Zn in a contaminated soil. As a result, CO 2 -C release is a sensitive index of the soil quality, at least in the experimental conditions of this essay.

“…Clay minerals are reported to decrease metal mobility in contaminated soil by changing soil properties such as soil pH (van Hervijnen et al 2007). In this study, sepiolite contained a significant percentage of calcium carbonate (CaCO 3 ) and had a high pH of 10.1. pH-dependent exchange sites on organic matter and oxide clay minerals can be ionized with increasing soil pH, which can increase the adsorption of Cd to soil colloids or soil clay particles (Tapia et al 2010).…”

Purpose The aim of this study was to evaluate the effectiveness of soil amendments and foliar fertilizer on Cd and Pb immobilization in contaminated soils. Materials and methods A field experiment was conducted in contaminated soils, wherein four amendments (sepiolite (SE), single superphosphate (SSP), triple super phosphate (TSP), calcium magnesium phosphate (CMP)) in combination with one foliar fertilizer (ZnSO 4 ) were investigated to reduce Cd and Pb bioavailability in calcareous soils. Total Cd and Pb concentrations in wheat, soil, and amendments were determined using inductively coupled plasma mass spectrometry. Available concentrations of Cd and Pb in soils were extracted using diethylenetriamine pentaacetic acid. Results and discussion The results indicated that application of these amendments and foliar fertilizer significantly decreased Cd availability in soils and Cd accumulation in wheat (P < 0.05); however, the soil amendments plus Zn fertilizer did not significantly decrease Cd and Pb concentrations in wheat. Compared with the control, application of soil amendments effectively reduced the available Cd and Pb in soils by 25.69~54.13% and 9.86~42.14%, respectively. Accordingly, the reduction of Cd and Pb concentrations in wheat grain by the soil amendments was 20.68~41.38% and 23.68~55.26%, respectively.Conclusions Among all the treatments, the addition of SE + SSP and SE + CMP exhibited the most efficiency in reducing Cd and Pb availability, respectively, in the soil.

“…These minerals have been increasingly used for soil remediation (Herwijnen et al 2007), land erodibility control (Andry et al 2009), soil properties improvement (Filcheva & Tsadilas 2002), and nitrogen use efficiency (Tarkalson & Ippolito 2011;Aghaalikhani et al 2012) in recent decades. Vermicomposts are also organic soil amendments that have been successfully used for improvement of soil physical, chemical and biological properties and thereby increasing crop yield (Kamali et al 2010;Kalantari et al 2011;Nada et al 2011).…”

Najafi-Ghiri M. (2014): Effects of zeolite and vermicompost applications on potassium release from calcareous soils. Soil & Water Res., 9: 31-37.Zeolite and vermicompost applications to soil may improve K fertility of soils. For this purpose, these materials were added to five representative calcareous soils collected from southern Iran. The treatments included (1) control, (2) 20 g/kg zeolite, (3) 20 g/kg vermicompost, and (4) 20 g/kg vermicompost + zeolite (1:1). The samples were incubated for 90 days, and the concentrations of soluble, exchangeable, and non-exchangeable K and K release rate to 0.01M CaCl 2 during 240 min (16 successive 15 min extractions of soil samples with CaCl 2 solution) were determined. Results indicated that zeolite application increased significantly the concentration of soluble and exchangeable K. Vermicompost application had a positive effect on all forms of K. Cumulative K release was also affected by vermicompost application. Comparison of experimental data to different kinetic models indicated that Elovich, power function, and parabolic diffusion models described well kinetics of K release from all soil samples to 0.01M CaCl 2 . The b values of Elovich equation had significant relationships with NH 4 OAc-and HNO 3 -extractable K. It is recommended that for K fertility management of calcareous soils, organic and inorganic amendments application to soils should be taken into consideration.
