“…These soils are developed in the Guamá and Tapajós river basins. The oxidation-reduction process and the deposition of sediment explain the high concentration of these elements in the floodplain soils when compared to the soils that are developed in the upland regions and on sedimentary rocks (Carvalho Filho et al, 2011). Mn oxide concentration in the floodplain areas was up to 25 times higher than the Mn oxide concentration found in the soils that were developed in well-drained conditions that suffer little influence from a hydrological regime and that naturally have low concentrations of Mn oxides (Thanachit et al, 2006).…”

Abstract. Amazonian soils are heterogeneous. However, few studies have been carried out in the Amazon, mainly because of its considerable size, which complicates the collection of data and the ability to plan for the sustainable use of natural resources. In this study, the physical, chemical, and mineralogical attributes of soils in the state of Pará, Brazil, were characterized by examining the particle size, fertility, silicon extracted by sodium hydroxide, iron, and aluminum, and manganese extracted by sulfuric acid, sodium citrate-bicarbonate-dithionite, and ammonium oxalate + oxalic acid. A descriptive analysis, multivariate principal component analysis, and cluster analysis were performed. The soils had low concentrations of bioavailable P, Ca2+, Mg2+, and K and had high concentrations of Al3+, Si, and Al oxide in the Cambisols. Concentrations of Fe and Mn oxides were higher in both the Cambisols and Nitosols, which are rich in oxidic minerals. The multivariate analysis indicated an association between the organic carbon content and pH, P, Ca, Mg, and K concentrations. An additional association was observed between clay, potential acidity, and the Fe and Al oxide concentrations.

“…On a large scale, there are some national element dispersion maps, such as those covering Spain (IGME 2012), USA (Shacklette and Boerngen 1984), India (Chandrasekaran and Ravisankar 2015), Serbia (Mihailovic et al 2015), England and Wales (Rawlins et al 2012), Lithuania (Marcinkonis et al 2011), Ireland (Fay et al 2007), and northern Europe (Reimann et al 2003). However, the large scales of the national maps are not appropriate for regional areas, where the unique nature of the parent materials may produce natural enrichments or the absence of elements that are not taken into account on a general scale.…”

Castilla-La Mancha (central Spain) is a region characterized by significant agricultural production aimed at high-quality food products such as wine and olive oil. The quality of agricultural products depends directly on the soil quality. Soil geochemistry, including dispersion maps and the recognition of baselines and anomalies of various origins, is the most important tool to assess soil quality. With this objective, 200 soil samples were taken from agricultural areas distributed among the different geological domains present in the region. Analysis of these samples included evaluation of edaphological parameters (reactivity, electrical conductivity, organic matter content) and the geochemistry of major and trace elements by X-ray fluorescence. The dataset obtained was statistically analyzed for major elements and, in the case of trace elements, was normalized with respect to Al and analyzed using the relative cumulative frequency (RCF) distribution method. Furthermore, the geographic distribution of analytical data was characterized and analyzed using the kriging technique, with a correspondence found between major and trace elements in the different geologic domains of the region as well as with the most important mining areas. The results show an influence of the clay fraction present in the soil, which acts as a repository for trace elements. On the basis of the results, of the possible elements related with clay that could be used for normalization, Al was selected as the most suitable, followed by Fe, Mn, and Ti. Reference values estimated using this methodology were lower than those estimated in previous studies.

ABSTRACT In present study, an ideal bivalent extraction system was selected and optimized for phenolic extraction of pomegranate peel .Study reported ethanol: ether bivalent solvent system with phenolic content having potent antioxidant activity. Selected bivalent system was optimized for extraction using response surface methodology (RSM). A Box–Behnken design was employed to analyze the effects of variables (temperature, time and peel concentration) on the extraction of total phenolic content, and antioxidant capacity (FRAP). The optimization study suggested extraction with 2.9% pomegranate peel for 8 hours at 40 OC was found the best for extraction of phenolic compound with potent antioxidant activity. RSM was shown to be an adequate approach for modeling the extraction of phenolic compounds from pomegranate peel.The pomegranate peel was extracted using optimized parameters and extract was concentrated in rotary vacuum evaporator at 45 oC for 6 hours. The concentrated extract was used to formulate antioxidant enriched ice cream product. The ice–cream formulation containing 1% of peel extract was found to be more acceptable in terms of sensory parameters. Proximate analysis of acceptable formulation reveals 3.54% protein, 3.51% fat, 22.24% carbohydrate, 0.83% ash, and 69.88% moisture, however62.871 DPPH % inhibition and 84.96 mg/100ml of AAE, FRAP activity and 363.266 mg/100 ml of GAE phenolic content was also reported with ice cream enriched with 1%peel extract Results shown the antioxidant enriched ice cream could be formulated using extract of pomegranate peel powder with good sensory properties.
