Spatial variability of soil fertility and its relationship with seed physiological potential in a soybean production area

The correlation of soil fertility x seed physiological potential is very important in the area of seed technology but results published with that theme are contradictory. For this reason, this study to evaluate the correlations between soil chemical properties and physiological potential of soybean seeds. On georeferenced points, both soil and seeds were sampled for analysis of soil fertility and seed physiological potential. Data were assessed by the following analyses: descriptive statistics; Pearson's linear correlation; and geostatistics. The adjusted parameters of the semivariograms were used to produce maps of spatial distribution for each variable. Organic matter content, Mn and Cu showed significant effects on seed germination. Most variables studied presented moderate to high spatial dependence. Germination and accelerated aging of seeds, and P, Ca, Mg, Mn, Cu and Zn showed a better fit to spherical semivariogram: organic matter, pH and K had a better fit to Gaussian model; and V% and Fe showed a better fit to the linear model. The values for range of spatial dependence varied from 89.9 m for P until 651.4 m for Fe. These values should be considered when new samples are collected for assessing soil fertility in this production area.

Nietzsche como destino da filosofia e da humanidade? interpretação contextual do § 1 do capítulo "por que sou um destino", de ecce homo

The following translation is a reduced and revised version of the paper Schicksal Nietzsche? Zu Nietzsches Selbsteinschätzung als Schicksal der Philosophie und der Menschheit (Ecce Homo, Warum ich ein Schicksal bin §1)" - originally published in Nietzsche-Studien 37 (2008) - which was specially prepared to be presented in lecture organized by the Grupo de Pesquisa Spinoza & Nietzsche (Spinoza & Nietzsche research group - SpiN), in the Universidade Federal do Rio de Janeiro (Rio de Janeiro's Federal University), on September 14, 2009. In the text, the autor employs his own philological-hermeneutical methodology, which is called contextual interpretation, in the purpose to clarify the concepts of the first aphorism from "Why I am a destiny", from Ecce Homo, in its own context, in the context of Ecce Homo and in the context of the entire work from Nietzsche.

Nietzsche como destino da filosofia e da humanidade? interpretação contextual do § 1 do capítulo "por que sou um destino", de ecce homo

A tradução que se segue é uma versão resumida e revisada do artigo "Schicksal Nietzsche? Zu Nietzsches Selbsteinschätzung als Schicksal der Philosophie und der Menschheit (Ecce Homo, Warum ich ein Schicksal bin §1)" - publicado originalmente em Nietzsche-Studien 37 (2008) - que foi especialmente preparada para ser apresentada em palestra organizada pelo Grupo de Pesquisa Spinoza & Nietzsche (SpiN), na Universidade Federal do Rio de Janeiro, em 14/09/2009. No texto, o autor faz uso de sua própria metodologia filológico-hermenêutica, denominada interpretação contextual, com vistas a esclarecer os conceitos do primeiro aforismo de "por que sou um destino", de Ecce Homo no seu contexto próprio, no contexto de Ecce Homo e no contexto da obra de Nietzsche como um todo.
