Web software to create thematic maps for precision agriculture PAB
Borges,Ligia Francielle; Bazzi,Claudio Leones; Souza,Eduardo Godoy de; Magalhães,Paulo Sergio Graziano; Michelon,Gabriela Karoline.
Abstract: The objective of this work was to develop and provide a free web application able to generate thematic maps. The initiative aims to incorporate the functionalities of the “Software para Definição de Unidades de Manejo” (SDUM) desktop application, which has proven to be suitable for working with thematic maps and management zones, but that was only available for desktop computers. The developed web application was tested with real data from two agricultural fields located in the state of Paraná, Brazil. Thematic maps of soil and plant characteristics relevant to precision agriculture were created through the following interpolation methods: inverse distance, moving average, and nearest neighbor. The obtained results show that the usage of this web...

Camicia,Rafaela Greici da Motta; Maggi,Marcio Furlan; Souza,Eduardo Godoy de; Bazzi,Claudio Leones; Konopatzki,Evandro André; Michelon,Gabriela Karoline; Pinheiro,José Bruno Santos.
ABSTRACT: The present study aimed to assess the efficiency of sowing at variable rates for soybean cultivation in two management zones (MZs) which were defined based on stable attributes and correlated with productivity using the Fuzzy C-means clustering algorithm and the kriging interpolation.Seeding was carried out in the 2015/2016 and 2017/2018 crops with a variation of 20% of seeds and crop row spacing of 0.70m. In each MZ, 8 plots with higher and lower seed density were established. Productivity was measured using a harvest monitor connected to a harvester. Data were filtered and submitted to descriptive analysis. Productivity maps were generated using the inverse square distance interpolation for each seeding density. In the MZ with the highest...
