Proteomics:A New Diagnostic Horizon In Periodontics.

Abstract An attempt to incorporate the popular systematic of urban soils proposed by Marina Stroganova with colleagues into the new Russian soil classification system is presented. It was facilitated by the coincidence of approaches in both systems: priority of diagnostic horizons and their combinations as criteria to identify soil types being the main units in all Russian classifications. The central image of urban soils . urbanozem . in Stroganova.s system found its due place in the order of stratozems (urbostratozem type) owing to its diagnostic horizon . urbic, which combines artificial and natural properties, and to its simultaneous formation with the parent material.

Na região amazônica é comum a conversão de ambiente natural para o de cultivo, com isso o solo permanece em constantes modificações. As atividades agrícolas podem incrementar a heterogeneidade do solo provocando alterações nos atributos químicos do solo, decorrente principalmente das atividades de manejo e cultivo. Essas mudanças são mensuráveis e contribuem para caracterizar, avaliar e acompanhar as alterações ocorrida utilizando ferramentas estatísticas. Assim o estudo da variabilidade espacial dos atributos químicos dos solos é particularmente importante especialmente em áreas onde o solo está submetido a diferentes manejos, visando reduzir os efeitos da variabilidade na produção das culturas em função de determinadas práticas de manejo. Dessa forma, este trabalho tem por objetivo avaliar a variabilidade espacial dos atributos químicos em área de floresta natural e com cultivo de laranja em Colorado do Oeste, Rondônia. Foram selecionadas duas áreas de estudo, a primeira sendo a área de floresta nativa e a segunda sob cultivo de laranja em de Colorado do Oeste, Rondônia. Em cada área foi delimitada uma malha com 1.260 m² (42 x 30 m), com 48 pontos e espaçamento regular entre pontos de 6 m. Nos pontos de cruzamento da malha foram coletadas amostras em três profundidades (0,00-0,05; 0,05-0,10 e 0,10-0,20 m), correspondente ao horizonte diagnóstico do solo, perfazendo uma somatória de 144 amostras por área, logo, um total de 288. Serão determinados dos atributos químicos de pH em água, acidez potencial, alumínio trocável, fósforo e potássio disponível, e carbono orgânico. Com a obtenção dos dados, estes foram avaliados por meio de estatística descrita com teste de médias e a realização da análise multivariada. Houve diferença entre as duas áreas, a substituição da vegetação nativa por sistema de cultivo, ocasionou alterações nos atributos químicos do solo. O uso das técnicas multivariadas mostrou-se eficiente na distinção dos ambientes estudados. Interaction of the chemical attributes of the soil in an area with natural forest and with planting of orange (Citrus sinensis L. Osb.) A B S T R A C TIn the Amazon region it is common to convert from a natural environment to that of cultivation, with this the soil remains in constant modifications. Agricultural activities can increase the heterogeneity of the soil causing changes in the chemical attributes of the soil, mainly due to management and cultivation activities. These changes are measurable and contribute to characterize, evaluate and monitor the changes that have occurred using statistical tools. Thus, the study of the spatial variability of the chemical attributes of soils is particularly important, especially in areas where the soil is subjected to different managements, in order to reduce the effects of variability in the production of crops due to certain management practices. Thus, this work aims to evaluate the spatial variability of chemical attributes in an area of natural forest and with orange cultivation in Colorado do Oeste, Rondônia. Two study areas were selected, the first being the native forest area and the second under orange cultivation in Colorado do Oeste, Rondônia. In each area, a mesh of 1,260 m² (42 x 30 m) was delimited, with 48 points and regular spacing between points of 6 m. At the crossing points of the grid, samples were collected at three depths (0.00-0.05; 0.05-0.10 and 0.10-0.20 m), corresponding to the soil diagnostic horizon, making a sum of 144 samples per area, therefore, a total of 288. The chemical attributes of pH in water, potential acidity, exchangeable aluminum, available phosphorus and potassium, and organic carbon will be determined. Once the data were obtained, they were evaluated using statistics described with the means test and the multivariate analysis. There was a difference between the two areas, the replacement of native vegetation by a cultivation system, caused changes in the chemical attributes of the soil. The use of multivariate techniques proved to be efficient in distinguishing the studied environments.Keywords: Amazon soils, Use and management, Soil occupation.

There is a variation in the depth of subsurface horizon of Planosols in semi-arid region, which may influence the agricultural potential and affect food production. The general aim of this study was to identify potentialities and limitations of two Planosols as a function of subsurface horizon depth. The adjacent profiles P1 and P2 were studied in Pentecoste (Ceará, Brazil). Morphological, physical, and chemical analyses were done aiming at soil characterization. Soil bulk density (BD), porosity, and penetration resistance (PR) were analyzed in a completely randomized split-plot design with four replicates to compare P1 and P2 and the horizons Ap and Btf. Btf was found at 62cm depth in P1 and at 18 cm depth in P2. Indicatives of water saturation were more evident in P2. The profile P1 showed lower hardness and higher friability, as well as higher acidity in subsurface (pHH2O from 4.4 to 4.7) and higher aluminum content (1.2cmolc kg-1). Both profiles were eutrophic and showed low contents of organic carbon (1.5 to 8.5g kg-1) and phosphorus (0.9 to 3.9mg kg-1). The sodium percentage in CEC was 9.1% in P1 and 5.5% in P2. Water retention increases in Btf compared with Ap was 7.3% in P2 and 2.7% in P1. Both profiles showed increase in BD in Btf, reaching 1.7g cm-3, while PR was higher in P2 (1.5 MPa). There are potentialities and limitations common to both soil profiles, but P1 has more physical potentialities and more chemical limitations than P2.

Areas under greyic phaeozems of Romania corresponding geographical areas as compared lithostratigraphic are made of clay and marly clay with frequent intercalations of sands and sandstones in a thick package, belonging Sarmatian, respectively, Volhinian and Basarabian, which directly influences the characteristics of the parent material of the soil.In this way, due to differences in altitude, these soils were formed and evolved deposits vary in granulometric composition, it is represented by loess, loess-like deposit, loam and loess, marly clay.Thus, we believe that the presence greyic phaeozems of our country in eastern, the genesis and evolution of the important role they have parental materials rich in fine sand fraction (31-41%). Specific these soils is the formation of humic acids and precipitate in place, under the influence of calcium ions, contributing to the development and the individualization of the horizon Am.Fulvic acids from the breakdown of litter cvercinee does not precipitate in the upper horizon, but migrate to the base, they favoring the migration is known as the iron and aluminum hydroxides and enriching the waste in the lower part of the quartz diagnostic horizon for greyic phaeozems, and a clay horizon B argic migrated upper horizon.

The “Systematics of Polish Soils” (SgP, 2011) is very close to WRB and “Soil Taxonomy”. The morphological characteristics of the soils, investigated in the field, rather than soil genesis are diagnostic criteria. The main provisions of the new “Systematics”, properties of soils of higher taxonomic levels have been reviewed. Some diagnostic horizons, which were not borrowed from other classifications, have been described. We tried to find equivalents in the Ukrainian classification for some soils names. The correlation of Poland soils and WRB has been analyzed. Key words: Systematics of Polish Soils, classification, order, soil type, diagnostic horizon, WRB.

Diagnostic Horizon

Anthropogenic pressure on our agricultural land is culminating last hundred years, especially after 1948, not only because of only massive application of mineral fertilizers but also because of land consolidation and subsequent accelerated water and wind erosion and use of mechanization. This article focuses on main demonstration of feedbacks especially with oxidizable carbon which can negatively affect soil as a homeostatic system. Oxidizable carbon, as the basis of soil humus, is crucial for maintaining soil fertility and for its resistance to further degradation factors affecting the soil. 35 chernozem sites were selected in South Moravia region. These soils had been probably used for their fertility and availability before the turn of the AD. Unfortunately, their long-term agricultural use has resulted in adverse impact on their quality.This way, shallower forms of erosion were often formed. These erosion forms are omitted for the purposes of our study there. For this work, locations with preserved chernic (i.e. diagnostic) horizon, as the horizon with less anthropogenic influence, were selected. Relations between a grain size (clay, silt and sand particles), exchange reaction in soil, sorption capacity, oxidizable carbon content, total nitrogen content and content of selected potentially acceptable elements (Ca, Mg) were monitored.
