Atributos físico-químicos de solos cultivados com videira sob manejo ecológico: um estudo de caso no assentamento Nova Estrela

Abstract

The objective of this study was to characterize the soil management systems adopted by family farmers, producers of organic vine certified on Nova Estrela Settlement. Three agricultural units (UAs) were selected, accounting for 43% of organic properties certified and presenting in common the same pedogenic and geomorphological, meteorological and pluviometric characteristics. A survey was carried out of the management adopted in the past and in the present time in the UAs, associate with the current fertility soils characterization through chemical analysis and the characterization of the physical soils condition through the Visual Evaluation of Soil Structure (VESS). The management system adopted in the production of organic vines has maintained the chemical and physical quality of the soil, as a consequence of the maintenance of the high organic matter content soil, a natural feature of the soils of the Campos de Cima da Serra region. The maintenance of soil cover with the use of cover crops associated to the input of organic resources is fundamental importance for the guarantee of soil organic matter contents. The adoption of management practices with agroecological bases was a key for the promotion of these results, consolidating itself as an important tool for the development of conscious environmentally agriculture.
