“…O valor médio da porosidade total encontrado nas amostras de solo avaliadas foi de 51,36%. De acordo com Kiehl (1979), para a produção agrícola, é considerado ideal que o solo apresente uma porosidade total próxima a 0,50 m³ m -³, juntamente com uma distribuição percentual de 34% para macroporos e 66% para microporos, sendo o limite crítico para a porcentagem de macroporosidade de 10% (SILVA et al, 2022), valores inferiores a este afetam severamente todo o desenvolvimento da cultura, pois a distribuição dos poros está diretamente relacionada a capacidade de drenagem, retenção de água do solo e aeração.…”

“…A distribuição do tamanho das partículas do solo é o parâmetro mais utilizados nas Funções de Pedotransferência, uma vez que parcialmente determina a área superficial das partículas sólidas responsável pela retenção de água, o arranjo das partículas e, consequentemente, a distribuição do tamanho dos poros e a organização estrutural (MICHELON et al, 2010;AMORIM et al, 2022). Todos esses fatores estão diretamente relacionados à capacidade de retenção de água no solo.…”

“…A maioria dos solos encontrados em Mato Grosso são conhecidos como Latossolos. Esses solos possuem um elevado teor de argila e apresentam uma estrutura bem organizada, o que resulta em uma alta condutividade hidráulica (VELOSO et al, 2023), no entanto essa classe de solos geralmente apresentam uma transição abrupta entre poros muito grande e muito pequeno, denominados de distribuição bimodal de poros (CARDUCCI et al, 2011;AMORIM et al, 2022), sendo esse um dos motivos pelos quais funções de pedotransferência desenvolvidas em solos temperados não possuírem bons ajustes quando aplicadas em solos de clima tropical (OTTONI et al, 2018).…”

Foram selecionadas 7 áreas localizadas em Mato Grosso, das quais foram coletadas amostras deformadas e indeformadas, com vistas à análise de um conjunto de atributos físicos e físico-hídricos. A partir das análises das amostras foram avaliadas quatro funções de pedotransferência e um software, obtidos em publicações. Para a validação do desempenho das funções utilizou-se o coeficiente de Pearson, raiz quadrada do erro médio, índice de concordância e o índice de desempenho. O conteúdo de água disponível correlaciona-se com a microporosidade e a granulometria do solo, funções geradas a partir dessas variáveis preditoras apresentam bons coeficientes de determinação. Parte das funções testadas apresentaram baixa acurácia na estimativa do conteúdo de água, com exceção das funções de Rosseti et al. (2022) na tensão de 0,033 MPa e Nascimento et al. (2010) na tensão de 1,5 MPa, podendo ser utilizadas para predição do conteúdo de água nos respectivos potenciais. Funções de pedotransferência podem ser empregadas para estimar o limite superior e inferior de retenção de água no solo quando não extrapoladas para além do local de origem. Palavras-chave: Relação solo-água, atributos físico-hídrico, disponibilidade hídrica, função de pedotransferência. SANTOS, D. A. T.; SILVA, T. J. A. S.; FELETTI, R.C. G.; BONFIM-SILVA, E. M.; MORAES, M. F.; AZEVEDO, E. C. UPPER AND LOWER LIMIT OF WATER RETENTION IN SOIL: LABORATORY METHOD AND ESTIMATION 2 ABSTRACT This study aimed to compare the values estimated by pedotransfer fuctions with the data from soil water retention limits, observed in the laboratory. We selected 7 areas located in Mato Grosso, from which deformed and deformed samples were collected, with a view to the analysis of a set of physical and physical-hydric attributes. From the analysis of the samples, four pedotransfer functions and one software obtained in publications were evaluated. To validate the performance of the functions, Pearson coefficient, square root of the mean error, agreement index and performance index were used. The available water content correlates with the microporosity and granulometry of the soil, functions generated from these predictor variables presente good coefficients of determination. Part of the tested functions showed low accuracy in estimating water content, with the exception of the functions of Rosseti et al. (2022) at the tension of 0.033 MPa and Nascimento et al. (2010) at the tension of 1.5 MPa, which can be used to predict the water contente in the respective potentials. Pedotransfer functions can be employed to estimate the upper and lower limit of soil water retention when not extrapolated beyond the place of origin. Keywords: Soil-water relationship, physical-water attributes, water availability, pedotransfer function.

“…Furthermore, the sandy soil texture explains the observed low water retention and availability [74][75][76][77][78][79][80], requiring soil coverage to reduce water evaporation and augment organic matter to improve water retention. Greater retention capacity in the soil surface of biodynamic orchards (Co and Cs) for all water tensions (matric potentials), followed by F200, shows the importance of soil organic matter and structure in water retention and availability to plants [81,82].…”

Citrus crop management has evolved to improve the quality of orchards and production, encompassing agroforestry and agroecological management practices. We sought to analyze different management systems in different seasons of the year, evaluating the quality of the soil physical, chemicals and biological properties, and the herbaceous vegetation occurring in citrus orchards. Five sites were studied: citrus in agroforestry and biodynamic systems (Cs), citrus in biodynamic systems (Co), citrus in conventional systems (Cc), and two forest sites, one with 40 (F40) and another with 200 years of regeneration (F200). Soil properties were evaluated in three layers (0–5, 5–20, and 20–40 cm) in four seasons, while the herbaceous survey was carried out in two of these seasons. The results showed that the Co and Cs orchards had better indicators in terms of chemical (pH, phosphorus, cation exchange capacity, and soil organic carbon (SOC)), physical (soil density, total porosity, and macro- and microporosity), and biological properties (global enzymatic activity) than the Cc management. The agroforestry management was even superior in soil quality, with improved pH levels, microporosity, and feeding behavior of the soil fauna. The most evident temporal variations were for pH, SOC, global enzymatic activity, and feeding activity of the soil fauna. The Cs and Co orchards showed greater richness and abundance of herbaceous species. Organic management favors a timely coverage of multiple benefits, with the presence of the Commoliaceae and Fabaceae families, and offering an ecological effect and green manure of high ecosystem value. In conclusion, agroforestry and biodynamic management systems are the best options to maintain soil quality and functioning for citrus production.

“…These models use easily measurable soil properties (soil texture and soil organic matter) to predict complex soil properties. Several PTFs were developed to estimate different soil properties such as bulk density (Brahim et al, 2012;Sevastas et al, 2018), soil erodibility (Zhu et al, 2022), cation exchange capacity (Enang et al, 2022), and soil hydraulic properties (Rudiyanto et al, 2021;Amorim et al, 2022;Acevedo et al, 2023).…”

Soil hydraulic properties are an important factor to optimize and adapt water management for a given crop. Pedotransfer functions (PTFs) present a solution to predict soil variables such as hydraulic properties, using fundamental soil properties. In this research, we compared two sources of soil information: iSDAsoil data and field data, in four regions in Morocco. We then used this data to evaluate published data and developed new PTFs using soil information to estimate soil gravimetric moisture content at saturation (w0), field capacity (w330) and permanent wilting point (w15000). A total of 331 samples were collected from four regions: Doukkala, Gharb-Loukous, Moulouya and Tadla. The data was divided into calibration and validation datasets. For development of different PTFs, we used simple linear regression, multiple linear regression, regression tree, Cubist algorithm, and random forest approaches. PTFs developed by Dijkerman (Geoderma, 1988, 42, 29–49) presented the best performance, showing lower RMSE, Bias and MAE compared to other PTFs. Using multiple linear regression to develop PTFs, models based on clay, silt and soil organic matter as input variables showed the best performance after calibration (R2 of 0.590, 0.785, 0.786 for w0, w330, and w15000, respectively). Regarding the techniques based on machine learning, random forest showed the best performance after calibration compared with other algorithms (R2 of 0.930, 0.955, 0.954 for w0, w330, and w15000, respectively). PTFs represent a low cost and easy technique to estimate soil hydraulic properties, to improve water management efficiency for the farmers.
