Soil sampling is decisive in determining its physical or chemical quality. In determining soil physical quality, methods for sampling undisturbed soil samples are not efficient from qualitative, financial, and ergonomic point of view, and it is necessary for the development of new collection methods. In this study, we developed a soil hydraulic sampler coupled to a tractor to collect undisturbed soil samples in different production systems. To validate the soil 'Hydraulic' sampler, an experiment was conducted in completely randomized design in 3 × 3 factorial arrangement with four replications. 'Uhland', 'Castle' and 'Hydraulic' samplers were used to collect soil undisturbed soil samples in three managements: no-tillage system, minimum cultivation and crop livestock integration system. Undisturbed soil samples were processed to determine soil bulk density, macroporosity, microporosity and total porosity. 'Uhland' sampler was not able to characterize the soil bulk density for different management systems, as there was a large variation coefficient in samples collected. 'Castle' sampler showed similar behavior for 'Hydraulic' sampler, differentiating studied agricultural systems. 'Hydraulic' sampler was efficient in collecting undisturbed soil samples, characterizing soil physical properties under different soil management systems. [ABSTRACT FROM AUTHOR] |
