“…is is inferred from what was found in regions with similar texture in "Maria da Conceição," probably due to the presence of native vegetation. Studying Haplic Cambisols, Oliveira et al [27] found that preserved forest areas presented the best water retention conditions, which is significantly correlated with S [35], thus endorsing the conjecture in the present work. Moreover, as illustrated in Dexter [11], the S index is mostly determined by soil organic carbon, being positively correlated [36], since organic carbon can increase water retention and improve pore distribution [37].…”

Land use and soil physical quality are related. In this work, the S index was used to evaluate the physical quality of the soils of three rural settlement units located in the Brazilian Cerrado, with areas ranging from 700 to more than 4000 hectares, based on a novel method. To map the S index, a set of pedotransfer functions for water retention curves was adapted according to a broad range of clay content for Cambisols, in three depth layers. Some rural units presented associations with classes of land use. In general, deeper layers presented higher values of S. In areas with less than 370 g/kg of clay, land uses that provide low soil cover should be avoided to prevent physical degradation.

“…ey were retrieved from a set of pedotransfer functions fitted by Oliveira et al [27] for Haplic Cambisols, as that was the dominant class found in the study areas. Estimates were clustered according to a broad range of clay content, as suggested by Souza et al [7] and Severiano et al [10].…”

“…Essas diferenças possivelmente decorrem de um maior teor matéria orgânica na subárea 1, cujo valor é 40% maior que na subárea 2. A respeito da importância da matéria orgânica do solo, ela exerce melhorias dos atributos químicos com o aumento da capacidade de troca catiônica (CTC), melhorias nos atributos biológicos e, também, nos atributos físicos, como por exemplo aumento da retenção hídrica do solo (Soares et al, 2019;Salomão et al, 2020;Oliveira et al, 2021).

Objetivou-se avaliar o índice de sobrevivência de espécies nativas do cerrado em função da calagem. O experimento foi realizado em uma microbacia do rio Pandeiros. A área experimental apresentava solo com baixo pH, baixa saturação por bases e fortes sinais de degradação antrópica. Na área de empréstimo à montante de terraços construídos com a finalidade de conter a erosão foi realizado o plantio de espécies florestais nativas pioneiras e não pioneiras, testando a ausência e a presença de calcário dolomítico nas covas de plantio. O plantio foi realizado em duas subáreas dentro da microbacia. Para a subárea 1, as espécies pioneiras testadas foram o Angico Vermelho (Anadenanthera macrocarpa), Aroeira (Lithraea molleoides) e Pau Ferro (Caesalpinia ferrea); já para a subárea 2 as espécies testadas foram: Gonçalo Alves (Astronium fraxinifolium), Carne de Vaca (Clethra scabra) e Farinha Seca (Albizia hasslerii). As espécies secundárias inicial e não-pioneira plantadas entre as espécies pioneiras foram respectivamente o Ipê Amarelo (Tabebuia ocharea) e o Jatobá (Hymenaea courbaril), sendo utilizadas essas espécies para as subáreas. Após 449 dias foi a avaliado o índice de sobrevivência das espécies pioneiras e não pioneiras para as subáreas 1 e 2. De maneira geral não se verificou efeito da calagem na sobrevivência de plantas. Para a subárea 1, a espécie com maior índice de sobrevivência foi o Pau Ferro. Para a subárea 2, a espécie com maior índice de sobrevivência foi o Gonçalo Alves. A subárea 1 apresentou maior índice de sobrevivência de espécies não pioneiras que a subárea 2.

“…Silva Neto et al ( 2012) also attributes the variation in water retention to the soil structure in addition to the distribution and size of the particles. Another attribution of water retention was described for Oliveira et al (2021), with greater contribution of the organic total carbon contents, hydrogenionic potential in water and macroprosity.…”

Physical and hydrological characteristics and modelling of the soil water retention curve in the brazilian semi-arid region

et al. 2022

Semiarid regions are characterised by water scarcity, a limiting factor on plant growth and development. The Sertão Canal was built in the semiarid region of Brazil, more specifically in the state of Alagoas, with the aim of making year-round irrigation possible. However, for the best water management, a physical and hydrological knowledge of the soils is necessary. As such, the aim of this study was to determine the physical and hydrological characteristics of three different types of soil (Argisol, Quartzarenic Neossol and Regolithic Neossol) under native vegetation (Caatinga) and agricultural systems in the semiarid region of Alagoas, as well as to adjust the soil water retention characteristic curves. Soil samples were collected at depths of 0-10, 10-20 and 20-30 cm in the municipalities of Inhapi, Delmiro Gouveia and Pariconha, in the state of Alagoas. The points of the moisture characteristic curve were determined by the Richards method, at pressures of 33, 100, 500, 1000 and 1500 kPa. Retention curves were modelled using the exponential decay equation and compared using the van Genuchten equation, modelled with the help of the RETC computer software. Particle size varied according to the textural classification of the different soils, from Sand to a Sandy Clay Loam. The retention curve fluctuated due to the particle size of the soil, with the Red-Yellow Argisol (Inhapi) having a greater capacity for water retention. Extremely sandy soils, such as those in the Delmiro Gouveia region, had a low capacity for retaining water. For each soil sample, the exponential decay equation gave the best fit, with values for R2adjust of greater than 0.93. When the measured soil moisture levels were compared with the levels estimated by the RETC model, some of the treatments were unable to estimate accurately the moisture levels obtained with the soil water retention curves.
