Assessment of heavy metals in soils of a vineyard region with the use of principal component analysis. Author(s): CARVALHO, J. R. P. de Agricultural management with chemicals may contaminate the soil with heavy metals. The objective of this study was to apply Principal Component Analysis and geoprocessing techniques to identify the or... ... Repository: BDPA Publication year: 2009
Soil organic carbon determination using NIRS: evaluation of dichromate oxidation and dry combustion analysis as reference methods in multivariate calibration. Author(s): SOUZA, A. M. de; COELHO, M. R. Dichromate oxidation and dry combustion analysis were evaluated as reference methods to determine organic carbon in Brazilian soils using near infrared spectroscopy (NIRS) as an alternative. The main... ... Repository: BDPA Publication year: 2016
Applications of laser-induced breakdown spectroscopy for soil characterization, part II: Review of elemental analysis and soil classification. Author(s): VILLAS BOAS, P. R.; MARTIN NETO, L.; MILORI, D. M. B. P. In-field soil health assessments, including plant nutrients and toxic elements, are needed and could improve the sustainability of agriculture production. Among the available analytical techniques for... ... Repository: BDPA Publication year: 2019
Analysis of Macronutrients in Soil Using Impedimetric Multisensor Arrays. Author(s): CORREA, D. S. ABSTRACT: The need to increase food production to address the world population growth can only be fulfilled with precision agriculture strategies to increase crop yield with minimal expansion of the c... ...

Functional analysis of soil chemical attributes using Geographic Information Systems to assess nutrient deficiencies. Information on soil fertility is essential to determine the need for correcting measures. However, the use of appropriate techniques to provide information on the specific potential of each soil in ma... ... Repository: BDPA Publication year: 2022
Sensitivity analysis of soils parameters and their influences on streamflow simulation in a small watershed, Northwest RJ, Brazil. Author(s): BHERING, S. The physical and hydraulic properties of soils in the watershed vary temporally and spatially, having a direct relationship with the amount of water that infiltrates, flows and reaches to the river ch... ... Repository: BDPA Publication year: 2014
Legacy data: exploratory analysis to digital soil class mapping. Author(s): CARVALHO JUNIOR, W. de; BHERING, S. B.; PEREIRA, N. R.; CHAGAS, C. da S. The use of legacy data improve the value of these data and promote the input of new data on the database. Also, reduces the primary data collection and analytical procedures. In MS State, the legacy d... ... Repository: BDPA Publication year: 2022
Multivariate analysis of images in spectrophotometric methods: quantification of soil organic matter. Author(s): MADARI, B. E. Soil organic matter (SOM) is usually quantified by Walkley-Black titration method or using a spectrophotometric method. This study proposes an alternative method for quantification of SOM using digita... ... Repository: BDPA Publication year: 2021
