21. Eficiência agronômica de fertilizantes fosfatados em solos com diferentes capacidades de adsorção de fósforo e teores de matéria orgânica / Agronomic efficiency of phosphate fertilizers in soils with different capacity of phosphate adsorption and organic matter levels
Tropical soils highly intemperized show increased capability on phosphorus (P) adsorption. Several factors may influence P adsorption in such soils, but special attention must be paid on the organic matter level. Mechanisms involved in this process are related to the release of organic acids derived from the decomposition of the organic matter, which may eit

24. RELAÇÃO ENTRE A COMPARTIMENTAÇÃO GEOMORFOLÓGICA E A OCORRÊNCIA DE ÁGATA E AMETISTA NO MUNICÍPIO DE QUARAÍ-RS / RELATION BETWEEN COMPARTMENTATION GEOMORPHOLOGIC AND THE OCCURRENCE OF AGATE AND AMETHYST IN THE QUARAÍ-RS BRAZIL.
The study of geomorphology takes place in the geographical science with the aid of other sciences such as geology. In these studies, the relief is a key element in the understanding of the relationship between the physical aspects (lithology, soil, vegetation, hydrography, climate, etc.) and the activities of human beings. Thus, to understand the interfaces
