Última Software Image J to study soil pore distribution Ciência e Agrotecnologia Passoni,Sabrina; Borges,Fernando da Silva; Pires,Luiz Fernando; Saab,Sérgio da Costa; Cooper,Miguel. In the soil science, a direct method that allows the study of soil pore distribution is the bi-dimensional (2D) digital image analysis. Such technique provides quantitative results of soil pore shape, number and size. The use of specific softwares for the treatment and processing of images allows a fast and efficient method to quantify the soil porous system. However, due to the high cost of commercial softwares, public ones can be an interesting alternative for soil structure analysis. The objective of this work was to evaluate the quality of data provided by the Image J software (public domain) used to characterize the voids of two soils, characterized as Geric Ferralsol and Rhodic Ferralsol, from the southeast region of Brazil. The pore distribution... Tipo: Info:eu-repo/semantics/article Palavras-chave: Soil structure; Image analysis; Thin section; Soil porous system; Soil pore size distribution; Ferralsols.

Solo Passoni,Sabrina; Pires,Luiz Fernando; Heck,Richard; Rosa,Jadir Aparecido. Analysis of the soil pore system represents an important way of characterizing soil structure. Properties such as the shape and number of pores can be determined through soil pore evaluations. This study presents a three-dimensional (3D) characterization of the shape and number of pores of a sub-tropical soil. To do so, a second generation X-ray microtomograph equipped with a plain type detector was employed. A voltage of 120 kV and current of 80 mA was applied to the X-ray tube. The soil samples analyzed were collected at three different depths (0-10, 10-20, and 20-30 cm). The results obtained allowed qualitative (images) and quantitative (3D) analyses of the soil structure, revealing the potential of the microtomographic technique, as well as the study...
