Mapeamento das Terras para Mecanização Agrícola - Estado da Paraíba

Abstract

Revista Brasileira de Geografia Física 02 (2012) Mapping of Land for Agricultural Mechanization -State of Paraíba A B S T R A C TThis study aimed to identify, quantify and map the lands of the State of Paraíba to agricultural mechanization and present a spatialized analysis of the limiting factors on the basis of suitability to the operations of tillage. The map of slope was generated from altimetry data file SRTM, using SPRING. The maps of the other attributes were di-agnostic interpretation of data obtained from soil survey of the Exploratory Soil-Recognition of the State of Paraíba. The map of classes and subclasses of land for mechanization was generated by crossing the map of the partial interpretation map of soil slope using the LEGAL. The results show that 82.85% of land in Paraíba are Class IV, V and VI of suitability to mechanization, which have respectively degree of limitation strong, very strong and extremely strong, and are located predominantly in the inner regions of semi-arid climate. The lands most suitable for mechanization are located on the coast, and to a lesser extent, in areas flatter interior dividers watersheds and flat tops of hills.

Zoneamento Agroclimático Do Melão Na Região Sudoeste De Mato Grosso

“…Na região investigada 93,47% de sua extensão territorial apresenta relevo plano à suave ondulado, sendo que a análise das fases de relevo de acordo com o IBGE (2007) prove informações sobre possibilidade do emprego de equipamentos agrícolas, normalmente os mecanizados, além de facilitar as inferências sobre suscetibilidade à erosão dos vários ambientes, o que possibilita ao agricultor produzir em consonância com a conservação ambiental. Sobre o assunto, Francisco et al (2012) expuseram que terras com valores maiores de que 40% de declividade (relevo forte ondulado) apresentam graus de impedimento à mecanização extremamente forte, por constituírem em superfície de topografia movimentada, com desníveis fortes, formadas por conjunto de outeiros ou morros, ou por superfície entrecortada por vales profundos (IBGE, 2007). Nessa lógica verificou que 2,09% das terras da região sudoeste matogrossense estão contempladas nessa categoria (Figura 6).…”

MAPPING OF PEDOLOGICAL POTENTIAL OF SOILS FOR CULTIVATION OF THE SUGAR CANE (Saccharum spp) IN PARAÍBA STATE USING GEOTECHNOLOGIES

“…According to Francisco et al (2012), with the advancement of information technology, the provision of satellite images at high resolutions and computer programs for environmental analysis, there has been a great progress in studies related to the management of natural resources. In this context, geoprocessing emerges as a discipline that uses a set of mathematical and computational techniques, in the form of programs, the geographic information system, which enables combinations of information from different technological procedures, generating new information that helps decision making, in different contexts (Duarte and Barbosa, 2009).…”

Agricultural mechanization in small rural properties in the State of Piau, Brazil

“…The planning and rational use of natural resources requires efficient and effective management, since efficient management will promote the preservation and conservation of the environment, benefiting sustainable development, and assisting farmers in decision making (Francisco et al, 2012). Based on this, the industrial revolution favored the advancement of technology in agriculture, using the necessary tools to expand the acreage, thus inserting agricultural mechanization as a strategic form of rural development and consequently increasing productivity (Francisco, 2010).…”
