Resumo: | The objective of this research was to evaluate the physical and hydric attributes of an Argissolo (Ultisol) in the peach orchard. The experiment was installed in a four-year-old peach orchard, in plots with and without irrigation, with soil sampling in two layers (0.00 to 0.05 m and 0.10 to 0.15 m), in the position of the orchard wheel line, interline planting, line planting and near the peach plant. Undisturbed soil samples were collected to evaluate the bulk density, porosity, diameter of aggregates, hydraulic conductivity, and water retention. It was observed that irrigation localized in the plants did not influence the physical and hydric attributes of the soil. However, the line and near the peach plant sampling positions showed greater macroporosity and hydraulic conductivity, and smaller bulk density, possibly due to the ridge made in the planting line and because there is no machine traffic in that positions. The traffic of machines increased bulk density in the interline, decreasing macroporosity mainly in the soil surface layer in the wheel position. The volume of available water was not very sensitive in identifying differences in relation to the effects of irrigation, soil layer and sampling position and of the variables related to soil structure. |

O experimento foi instalado em um pomar com quatro anos, em parcelas com e sem irrigação, onde foram coletadas amostras de solo em duas camadas (0,00 a 0,05 m e 0,10 a 0,15 m), nas posições de entrelinhas no rodado e entre o rodado das máquinas, e na linha entre e sob a copa das plantas. Amostras de solo com estrutura preservada foram coletadas para avaliação da densidade, porosidade, diâmetro de agregados, condutividade hidráulica e retenção de água. Observou-se que a irrigação localizada não influenciou os atributos físicos e hídricos do solo. Porém, as posições na linha e copa apresentaram maior macroporosidade e condutividade hidráulica, e menor densidade do solo, possivelmente pela construção do camalhão na linha de plantio e por não haver trânsito de máquinas nessas posições. O trânsito de máquinas fez aumentar a densidade do solo nas entrelinhas, ocorrendo diminuição da macroporosidade, particularmente, na camada superficial na posição do rodado. O volume de água disponível foi pouco sensível em identificar diferenças em relação aos efeitos da irrigação, camada de solo e posição no pomar e das variáveis relacionadas à estrutura do solo.Departamento de Diagnóstico e Pesquisa Agropecuária.
