ROCHA, Davi M. et al. Correlation and Spatial Dependence of Soil Attributes, Index Chlorophyll and Corn Yield. Rev. cienc. tecnol. [online]. 2016, n.25, pp.62-69. ISSN 1851-7587.

This study aimed to quantify the spatial dependence of soil chemical properties, chlorophyll index in stages V3, V6 and R1 and corn yield, and analyze the spatial correlation between them. Soil properties were evaluated in 2010 and 2011 and the rate of chlorophyll (with clorofilometro) and productivity in the years 2011 and 2012. The studied attributes presented spatial dependence structure, allowing the site-specific management. It also observed the existence of spatial correlation between attributes, demonstrating the importance of studies in this area, identifying which attributes influence the development of culture.
