Determination of management zones from normalized and standardized equivalent produtivity maps in the soybean culture

Abstract: Through the site-specific management, the precision agriculture brings new techniques for the agricultural sector, as well as a larger detailing of the used methods and increase of the global efficiency of the system. The objective of this work was to analyze two techniques for definition of management zones using soybean yield maps, in a productive area handled with localized fertilization and other with conventional fertilization. The sampling area has 1.74 ha, with 128 plots with site-specific fertilization… Show more

“…These questions are the focus of much research worldwide, aiming not only at answering them, but developing techniques and procedures that make affirmative answers to these questions. Thus, new forms of research on how to apply this technology study on lower sampling costs associated with sample size and the definition of management zones (TAYLOR et al, 2007;ROUDIER et al, 2008;RODRIGUES JR. et al, 2011;SUSZEK et al, 2012) emerges for making practical and economic PA.…”

“…Para Molin (2002) é necessário haver consistência temporal para a definição correta de unidades de manejo diferenciadas; portanto, a análise individual de mapas é restritiva e pode não representar, com autoridade, tais zonas. Desta forma, o uso de vários mapas de produtividade para a definição e consolidação de zonas com distintos potenciais produtivos parece ser a maneira mais eficiente para caracterizar a variabilidade das lavouras (Molin, 2002;Milani et al, 2006;Suszek et al, 2011).…”
