Author(s): VALLADARES, G. S.; CAMARGO, O. A. de; CARVALHO, J. R. P. de; SILVA, A. M. C. 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... ... |
Author(s): BELTRAME, K. K.; SOUZA, A. M. de; COELHO, M. R.; WINKLER, T. C. B.; SOUZA, W. E.; VALDERRAMA, P. 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... ... |
Author(s): VILLAS BOAS, P. R.; FRANCO, M. A. M.; MARTIN NETO, L.; GOLLANY, H. T.; 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... ... |

In this work, an analytical method for the determination of residues was optimized for the focus pesticides: Azoxystrobin, Boscalid, Carbendazim, Chlorantraniliprole, Clothianidin, Diafenthiuron, Dife... ... |
Author(s): BARBOSA NETO, M. V.; ARAÚJO, M. do S. B. de; ARAUJO FILHO, J. C. de; SILVA, C. B. da; SAMPAIO, E. V. de S. B. 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... ... |
Author(s): BRAZÃO, C.; SILVA, A.; FERNANDES, N.; 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... ... |
Author(s): CARVALHO JUNIOR, W. de; BHERING, S. B.; PEREIRA, N. R.; CHAGAS, C. da S.; LOPES, C. H. L. 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... ... |
Author(s): MORAIS, P. A. de O.; SOUZA, D. M. de; 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... ... |
