“…Nevertheless, the soils of the USA have greater AW content in most textural classes, compared to the soils of SC. This difference is probably due the predominance of soils with high activity clay of the 2:1 type (Nettleton et al, 1983;Rawls et al, 2003), while in SC soils with kaolinite, 2:1 type clay minerals with hydroxyaluminum interlayers and iron oxides predominate (Almeida et al, 1997(Almeida et al, , 2003Corrêa, 2003;Paes Sobrinho et al, 2009;Bringhenti, 2010). The increase in water availability provided by the 2:1 type clay minerals has not been studied in detail (Bruand, 2004b); nevertheless, the studies of Gaiser et al (2000) and Reichert et al (2009) indicate a positive relation between these soil properties.…”

SUMMARYThe retention and availability of water in the soil vary according to the soil characteristics and determine plant growth. Thus, the aim of this study was to evaluate water retention and availability in the soils of the State of Santa Catarina, Brazil, according to the textural class, soil class and lithology. The surface and subsurface horizons of 44 profiles were sampled in different regions of the State and different cover crops to determine field capacity, permanent wilting point, available water content, particle size, and organic matter content. Water retention and availability between the horizons were compared in a mixed model, considering the textural classes, the soil classes and lithology as fixed factors and profiles as random factors. It may be concluded that water retention is greater in silty or clayey soils and that the organic matter content is higher, especially in Humic Cambisols, Nitisols and Ferralsol developed from igneous or sedimentary rocks. Water availability is greater in loam-textured soils, with high organic matter content, especially in soils of humic character. It is lower in the sandy texture class, especially in Arenosols formed from recent alluvial deposits or in gravelly soils derived from granite. The greater water availability in the surface horizons, with more organic matter than in the subsurface layers, illustrates the importance of organic matter for water retention and availability.Index terms: field capacity, permanent wilting point, available water capacity, particle size, mixed models.( EFEITO DAS CLASSES TEXTURAIS, CLASSES DE SOLO E LITOLOGIASA retenção e a disponibilidade de água variam com os atributos do solo e determinam o crescimento das plantas. Nesse sentido, este estudo objetivou avaliar a retenção e a disponibilidade de água nos solos de Santa Catarina, em razão da classe textural, classe de solo e litologia. Foram amostrados os horizontes superficiais e subsuperficiais de 44 perfis de solo, em áreas de diferentes regiões do Estado e coberturas vegetais, para a determinação da capacidade de campo, ponto de murcha permanente, água disponível, granulometria e teor de matéria orgânica. A retenção e a disponibilidade de água foram comparadas entre os horizontes por meio de um modelo misto, considerando as classes texturais, classes de solo e litologias, como fatores fixos, e os perfis, como fatores aleatórios. A retenção de água foi maior em solos argilosos ou siltosos e com maior teor de matéria orgânica, especialmente nos Cambissolos Húmicos, Nitossolos e Latossolos desenvolvidos de rochas ígneas afaníticas ou sedimentares, como folhelhos, argilitos e siltitos. A disponibilidade de água foi maior em solos de textura franca, com elevados teores de matéria orgânica, principalmente nos com caráter húmico; e menor em solos da classe textural areia, principalmente nos Neossolos Quartzarênicos, formados a partir de depósitos aluvionares recentes ou em solos cascalhentos, derivados de granito. A maior disponibilidade de água nos horizontes superficiais, com m...

“…Particle‐size analysis was determined by sieve and pipette (3A1), following pretreatments to remove organic matter and soluble salts, and chemical dispersion with sodium hexametaphosphate. For statistical data evaluation, clay was estimated for samples with poor dispersion (1500 kPa water retention; clay percentage of >0.6) (Nettleton and Brasher, 1983; Soil Survey Staff, 1999a):

Major and Trace Elements of Selected Pedons in the USA

Few studies of soil geochemistry over large geographic areas exist, especially studies encompassing data from major pedogenic horizons that evaluate both native concentrations of elements and anthropogenically contaminated soils. In this study, pedons (n = 486) were analyzed for trace (Cd, Co, Cr, Cu, Hg, Mn, Ni, Pb, Zn) and major (Al, Ca, Fe, K, Mg, Na, P, Si, Ti, Zr) elements, as well as other soil properties. The objectives were to (i) determine the concentration range of selected elements in a variety of U.S. soils with and without known anthropogenic additions, (ii) illustrate the association of elemental source and content by assessing trace elemental content for several selected pedons, and (iii) evaluate relationships among and between elements and other soil properties. Trace element concentrations in the non-anthropogenic dataset (NAD) were in the order Mn > (Zn, Cr, Ni, Cu) > (Pb, Co) > (Cd, Hg), with greatest mean total concentrations for the Andisol order. Geometric means by horizon indicate that trace elements are concentrated in surface and/or B horizons over C horizons. Median values for trace elements are significantly higher in surface horizons of the anthropogenic dataset (AD) over the NAD. Total Al, Fe, cation exchange capacity (CEC), organic C, pH, and clay exhibit significant correlations (0.56, 0.74, 0.50, 0.31, 0.16, and 0.30, respectively) with total trace element concentrations of all horizons of the NAD. Manganese shows the best inter-element correlation (0.33) with these associated total concentrations. Total Fe has one of the strongest relationships, explaining 55 and 30% of the variation in total trace element concentrations for all horizons in the NAD and AD, respectively.
