The objective was to identify landscape areas with different patterns of variability using a statistic protocol with data of magnetic susceptibility (MS) and soil color that are covariate attributes of soil formation factors and processes. The studied area, of 380ha, is located in Northeast of São Paulo State, Brazil. An amount of 86 samples was collected using 30m intervals on the transect. At the...
Establishing a soil sampling plan is one of the most important stages for providing the detailed information required for sustainable land management. This study aims to investigate the most appropriate sampling density and proportion for the characterization of Oxisol attributes on different materials, using the magnetic susceptibility (MS). The studied area is located in São Paulo State, Brazil,...
There is a growing demand for detailed information on soil properties. This information can be used as a guideline for sustainable production. The objective of this work was to assess the use of magnetic susceptibility (MS) and diffuse reflectance spectroscopy (DRS) for characterizing the spatial variability of soil physical and chemical properties, as well as sites with different potentials for sugarcane...
Relief may be considered an integrating factor that expresses the interaction of various soil and plant attributes. This work aimed to analyze the potential use of landforms to predict the variability of soil and orange attributes. The study area is located in the state of São Paulo, Brazil. The following soil attributes were analyzed: clay content, organic matter content, water content, aggregate...
