Prospecção de zonas potenciais para manejo diferenciado em agricultura de precisão utilizando-se padrões de solo-planta-clima

Abstract: A agricultura de precisão contempla a aplicação da informação tecnológica aos processos produtivos. A implementação de programas nesta linha depende da integração de dados de solo, planta e clima, para a geração de informações úteis. O reconhecimento de padrões em propriedades de solo e planta, é fundamental para a viabilização de práticas nessa área, principalmente para uma abordagem de lavouras por zonas ou classes de manejo. Visando estudar aspectos do delineamento de zonas potenciais para manejo diferencia… Show more

“…The map generated for four management zones ( Figure 1C) showed behavior similar to that of the first map, with subgroups aligned in different zones. These results are similar to those reported by Santos et al (2003), who evaluated potential management zones in a 40-ha area cultivated with rainfed maize using soil-plant-climate patterns.…”

“…The recognition of patterns in attributes variability and soil and plant properties is crucial to the viability of different and localized management practices, mainly to an approach for crop management zones or classes (SANTOS et al, 2003). Understanding and classifying the variability of soil properties and landscape and its effects on crop productivity are important components for localized management of agricultural systems (JIANG & THELEN, 2004).…”

“…With the improvement of the computing machines, such techniques have increased its use. In agriculture circle, because of the complexity of soil and plants, some papers use these studies to correlate with soil quality and/or productivity of crops (XIN-ZHONG et al, 2009 andJARADAT, 2009). YE & WRIGHT (2010) correlated the soil use with changes of chemical attributes.…”
