ABSTRACT: In Brasil, Minas Gerais is the sixth state in soybean production. Adverse climatic conditions such as short mini-droughts (?veranicos?), irregular rainfall distribution and especially high temperatures can compromise the proper development of the crop in that state, especially in relation to the production of high quality seeds. The aim of this study was to collect and analyze data in order to establish an agro-climatic zoning of the state of Minas Gerais for the production of high quality soybean seeds. These values were georeferenced in terms of the latitude and longitude coordinates and, with the use of a geographic information system, a thematic map was created, in which the best growing regions in Minas Gerais are represented. The defnition of higher or lower climate risk areas was associated with the occurrence of average temperatures during the seed maturation phase, the most sensitive stage of growth. On the basis of the data obtained on temperature and altitude of different locations, and considering the normal growth period, it was possible to outline a map with three distinct areas: Favorable - average temperature < 23,5 oC; moderately favorable - average temperature between 23,6 oC and 24,9 oC; unfavorable - average temperature > 25,0 oC. RESUMO: Minas Gerais é o sexto estado em produção de soja no Brasil. Adversidades climáticas como veranicos, distribuição irregular das chuvas no decorrer do ano e principalmente temperaturas elevadas podem comprometer o bom desenvolvimento da cultura no Estado, principalmente no que se refere à produção de sementes de elevada qualidade. Diante disso, o objetivo desse estudo foi realizar um levantamento de dados com a fnalidade de estabelecer um zoneamento agroclimático para a produção de sementes de soja de elevada qualidade física e fsiológica. Esses valores foram georeferenciados em função da latitude e longitude e, com o uso de um sistema de informações geográfcas, foi confeccionado o mapa temático no qual estão representadas as melhores regiões para semeadura da cultura no Estado. A defnição das regiões de maior ou menor risco climático foi associada à ocorrência de temperaturas médias na fase de maturação da soja, considerada a fase de máximo potencial fsiológico da semente, e da altitude dos municípios, tudo isso considerando a época normal de semeadura da cultura. Com base nos levantamentos realizados, estabeleceram-se três classes de regiões: Favorável ? temperatura média < 23,5 oC; Medianamente Favorável - temperatura média entre 23,6 oC a 24,9 oC; Pouco Favorável - temperatura média > 25,0 oC.

The effect of residual vanadyl (VO2+) on data derived from the analysis of humic acids (HAs) by means of fluorescence spectroscopy, solid-state 13C nuclear magnetic resonance spectroscopy (NMR) and UV-Vis spectroscopy was examined in order to reveal potential organic groups involved in metal complexation. The HAs were extracted from agricultural soils from an experimental station in Campinas, Brazil. Their paramagnetic ion content was determined using electron paramagnetic resonance (EPR). Because of the well-resolved EPR signal, the VO2+ ion content was used for the correlation studies. The latter clearly demonstrated that residual VO2+ affects the spectroscopic data and that, besides the intrinsic structural characteristic of HAs, the impact of paramagnetic ions must be considered for careful interpretation of such data. On the other hand, analysis of these effects can give additional structural information. With respect to the UV-Vis spectra, the positive correlation between VO2+ content and the absorption at 665 nm (E6) was attributed to the presence of VO2+ complexes. Further support for metal-humic substance binding was extracted by way of a reduction in the fluorescence intensity with increasing VO2+ concentration for both excitation and emission. A relationship between the suppression of the intensity of the O-alkyl, di-O-alkyl and carboxyl C signals in the solid-state 13C NMR spectra and the VO2+ content demonstrated the involvement of carbohydrates in metal complexation, probably in the uronic acid form. No clear correlation was observed with respect to the O-aryl C signal, which may be due to a low accessibility of the metallic ion to methyl- substituted O-aryl groups as they occur in lignin derivatives.
