<b>Precision agriculture for sugarcane management: a strategy applied for brazilian conditions</b> doi: 10.4025/actasciagron.v36i1.17664

Abstract: ABSTRACT. The region of Areiópolis in São Paulo State is one of the major sugarcane producers in the world, and chemical management is the basis of the system making its production viable. Thus, the proposed methods for precision agriculture can be evaluated as an alternative for environment protection and can aid the search for greater productivity at the same time. The main objective of the present work was to compare the precision agriculture (PA) and traditional agriculture (TA) management systems and to h… Show more

“…The applications of these inputs at differentiated rates occurred according to the division of the area into three application zones or three classes, following the variability of the average input need in these zones. The chemical characterization of the soil in the field under PA techniques was carried out by a georeferenced sample in a quadratic grid with a point sample composed by ten subsamples every 5 ha (Baio & Leal, 2012;Demattê et al, 2014).The manipulation and interpolation of the data by the inverse of the distance in the elaboration of the maps were carried out with the aid of the SSToolbox Geographical Information Systems software, developed by SST Software (Stillwater, USA). The prescription maps have been inserted into field machines in applications at differentiated rates.…”

“…Los autores definen en su metodología la obtención de datos del cultivo que caracterizan las condiciones del mismo, la gestión y el análisis en bases de datos centralizadas y la facilidad en la accesibilidad de dicha información a los encargados del cultivo, para que tomen mejores decisiones relacionadas con el mismo. Demattê et al [11] informan acerca de comparaciones entre procesos de muestreo, producción, daño en cultivo y costos al utilizar procedimientos y tecnologías de AP y al cultivar comúnmente caña de azúcar en Brasil, por lo que presentan recomendaciones y soporte a decisiones, basados en requerimientos puntuales del sitio de estudio. Por otra parte, López et al [12] presentan resultados de desempeño de un sistema de recomendación de cinco fases para el uso de fertilizantes en cultivos de caña de azúcar, de donde indican los valores de nutrientes requeridos en cada dosis de fertilización aplicada.…”

“…La aproximación a un modelo de gestión, monitorización, simulación y comunicación se muestra en la figura 3, en donde se observa un conjunto de procesos divididos en dos partes para facilitar la toma de decisiones, gestión y monitorización. Fuente: [28] 1 Farmer's problem unstructured & situation under-specified 4 Flexible simulator 3 Problem situation better specified via on-farm monitoring and experimentation 2 Cooperative learning by farmers, advisers, and researchers with different world views 6 Researcher/Adviser simulating production system 5 Characterisation of soils 12 Soil and wather databases 11 Improve simulator 9 Management to improve the situation 8 En [29] se describe un análisis de datos para experimentos en AP, incluyendo aplicaciones para el caso de uso de la caña de azúcar. Este análisis se basa en la representación de técnicas de adquisición de datos, la estimación de ruido en cada medición, el análisis de autocorrelación espacial para cada atributo y el aná-lisis de componentes principales (PCA: Principal Component Analysis) de los mismos.…”

“…a história do Brasil se encontra tão intimamente ligada ao cultivo da cana-de-açúcar que se faz impossível uma dissociação". Nesse sentido, a tradição de mais de cinco séculos de seu cultivo somada às inovações tecnológicas intrínsecas ao setor sucroenergético, para alguns autores foram determinantes para o status de maior produtor e exportador de açúcar e etanol do mundo (Moraes & Michellon, 2010;Dunham, Bomtempo, & Fleck, 2011;Shikida, 2014;FAO, 2015 (Demattê, Demattê, Alves, Barbosa, & Morelli, 2014).…”

“…Porém, ao longo de sua história, o setor sucroenergético passou por períodos de contração e expansão, reflexos de flutuações de mercado e inconstância de incentivos governamentais, além do que, as estratégias de inovação não se estruturaram de forma coordenada e organizada em médio e longo prazo, em que pese êxitos pontuais (Carvalho & Furtado, 2013;Demattê et al, 2014;Shikida, 2014).…”
