“…In Australia, for example, Lamb et al (2008) emphasise as possible causes of the slight impact of PA (or PV), the cost of the technologies involved and the general reluctance of farmers to adopt technological changes. Cook and Bramley (1998) and Lamb et al (2008) coincide when pointing out that the void that exists between researcher and farmer has to some extent brought about the distancing (distrust) of the productive sector. If we add the fact that commissioning these new technologies and providing professional advice requires knowledge and skills that very few agents and/or consultants are currently able to offer, then the present stalemate is easy to understand.…”

Precision Viticulture (PV) is a concept that is beginning to have an impact on the wine-growing sector. Its practical implementation is dependant on various technological developments: crop sensors and yield monitors, local and remote sensors, Global Positioning Systems (GPS), VRA (Variable-Rate Application) equipment and machinery, Geographic Information Systems (GIS) and systems for data analysis and interpretation. This paper reviews a number of research lines related to PV. These areas of research have focused on four very specific fields: 1) quantification and evaluation of within-field variability, 2) delineation of zones of differential treatment at parcel level, based on the analysis and interpretation of this variability, 3) development of Variable-Rate Technologies (VRT) and, finally, 4) evaluation of the opportunities for site-specific vineyard management. Research in these fields should allow winegrowers and enologists to know and understand why yield variability exists within the same parcel, what the causes of this variability are, how the yield and its quality are interrelated and, if spatial variability exists, whether site-specific vineyard management is justifiable on a technical and economic basis.Additional key words: grape yield maps, local and remote sensors, selective vintage, within-field variability, yield monitor, zonal management. ResumenRevisión. Viticultura de precisión. Líneas de investigación, retos y oportunidades del manejo sitio-específico en viña La Viticultura de Precisión (VP) es un concepto que empieza a tener un cierto impacto en el sector vitivinícola. Su implementación práctica está ligada al desarrollo de cierta tecnología: sensores y monitores de cosecha, sensores locales y remotos, Sistemas de Posicionamiento Global (SPG), equipos y maquinaria de aplicación variable, Sistemas de Información Geográfica (SIG) y sistemas para el análisis y la interpretación de la información. En este trabajo se ha llevado a cabo una revisión de las diferentes líneas de investigación relacionadas con la VP. Dichas áreas de investigación se han centrado en cuatro ámbitos muy concretos: 1) cuantificación y evaluación de la variabilidad intraparcelaria, 2) delimitación a nivel de parcela de zonas de tratamiento diferencial, en base al análisis y la interpretación de dicha variabilidad, 3) desarrollo de tecnologías para la actuación variable en campo (variable-rate technologies, VRT) y, finalmente, 4) evaluación de la oportunidad del manejo sitio-específico en viticultura. La investigación en estos ám-bitos debe permitir a viticultores y enólogos conocer y comprender por qué la cosecha varía dentro de una misma parcela, cúales son las causas de dicha variación, cómo están interrelacionadas la cosecha y su calidad y, ante la existencia de variabilidad espacial, si está justificado técnica y económicamente el manejo diferencial de los viñedos.Palabras clave adicionales: manejo zonal, mapas de vendimia, monitor de cosecha, sensores locales y remotos, variabilidad intraparcelaria, vendimia...

ABSTRACT-The current high competition on Citrus industry demands from growers new management technologies for superior efficiency and sustainability. In this context, precision agriculture (PA) has developed techniques based on yield mapping and management systems that recognize field spatial variability, which contribute to increase profitability of commercial crops. Because spatial variability is often not perceived the orange orchards are still managed as uniform and adoption of PA technology on citrus farms is low. Thus, the objective of the present study was to characterize the spatial variability of three factors: fruit yield, soil fertility and occurrence of plant gaps caused by either citrus blight or huanglongbing (HLB) in a commercial Valencia orchard in Brotas, São Paulo State, Brazil. Data from volume, geographic coordinates and representative area of the bags used on harvest were recorded to generate yield points that were then interpolated to produce the yield map. Soil chemical characteristics were studied by analyzing samples collected along planting rows and inter-rows in 24 points distributed in the field. A map of density of tree gaps was produced by georeferencing individual gaps and later by counting the number of gaps within 500 m² cells. Data were submitted to statistical and geostatistical analyses. A t test was used to compare means of soil chemical characteristics between sampling regions. High variation on yield and density of tree gaps was observed from the maps. It was also demonstrated overlapping regions of high density of plant absence and low fruit yield. Soil fertility varied depending on the sampling region in the orchard. The spatial variability found on yield, soil fertility and on disease occurrence demonstrated the importance to adopt site specific nutrient management and disease control as tools to guarantee efficiency of fruit production. Index terms: Precision agriculture, spatial variability, citrus blight, huanglongbing (HLB). MAPEAMENTO DA PRODUTIVIDADE, FERTILIDADE DO SOLO E FALHAS DE PLANTAS EM POMAR DE LARANJEIRASRESUMO -A atual competitividade existente no setor citrícola demanda dos produtores novas estratégias de manejo para aumento de eficiência e sustentabilidade. Nesse sentido, a agricultura de precisão (AP) tem desenvolvido técnicas baseadas no mapeamento de produtividade e sistemas de manejos que reconheçam a variabilidade espacial existente no campo, o que contribui para aumentar a lucratividade de pomares comerciais. Como a variabilidade espacial normalmente não é visualizada, os pomares ainda são manejados como uniformes, e a adoção das tecnologias de AP nas fazendas citrícolas é baixa. Dessa forma, o objetivo do trabalho foi carcaterizar a variabilidade espacial de três fatores: produtividade de frutos, fertilidade do solo e ocorrência de falhas de plantas causadas pelo declínio dos citros e pelo (HLB), em um talhão comercial de citros em Brotas-SP.

“…Site-specific agriculture is sometimes associated with the need for high technological equipment such as sensorenabled devices, Global Positioning Systems (GPS) and Geographical Information Systems (GIS). Technology providers and developers are pushing stakeholders to continuously adopt the latest technologies (Lamb et al 2008). Nevertheless, precision agriculture (PA) should not be understood only as a high-tech discipline by definition (Molin 1997), but it has its roots in an 'observe-interpret-evaluate-implementation' methodology regardless of the means and tools used (Cook and Bramley 1998).…”

“…For example, the application of high positional accuracy involves implementation costs (Booltink et al 2001) and training time. This issue affects developing and developed countries alike since, in developed countries, the use of the latest technology in PA is not as widespread as believed (Lamb et al 2008). Indeed, in Southern Europe the use of sitespecific agriculture 'has been delayed because of small farm size' (Fountas et al 2010) among other reasons.…”

Participative site-specific agriculture analysis for smallholders

et al. 2012

Site-specific agriculture has been adopted in a high-tech context using, for instance, in situ sensors, satellite images for remote sensing analysis, and some other technological devices. However, farmers and smallholders without the economic resources and required knowledge to use and to access the latest technology seem to find an impediment to precision agricultural practices. This article discusses the possibility of adopting precision agriculture (PA) principles for site-specific management but in a low technology context for such farmers. The proposed methodology to support PA combines low technology dependency and a participatory approach by involving smallholders, farmers and experts. The case studies demonstrate how the interplay of low technology and a participative approach may be suitable for smallholders for site-specific agriculture analysis.
