“…The ultimate aim is to abandon the inflexibility associated with the idea of a parcel as the minimum territorial unit, and to move on to work with subparcels or zones which are delineated and treated differentially in accordance with their particular productive and/or qualitative characteristics. In short, Site-Specific Crop Management (SSCM) refers to crop management at a lower spatial scale than that of the parcel (Plant, 2001). …”

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...

RESUMOExiste carência de estudos enfocando o comportamento espacial de atributos químicos no Amazonas. Neste sentido, o objetivo deste trabalho foi utilizar técnicas geoestatísticas na avaliação de atributos químicos em solo de agrofloresta e cana-deaçúcar em Humaitá, Amazonas. O estudo foi realizado em uma propriedade rural em Humaitá, Amazonas. Nestas áreas foram estabelecidas malhas de 70,00 m x 70,00 m, com espaçamento regular de 10,00 m totalizando 64 pontos e em seguida, coletadas amostras de solos na profundidade de 0,0-0,20 e 0,40 -0,60 m. Foram determinados os atributos químicos (pH, MO, P, K, Ca, Mg, SB, CTC, V% e H+Al). Utilizaram-se técnicas de estatística descritiva e geoestatística de onde ajustaram semivariogramas individuais e escalonados, e em seguida, estimou a densidade amostral com base no alcance dos semivariogramas. Os atributos do solo apresentaram estrutura de dependência espacial na sua maioria, com predominância de grau de dependência espacial moderado, nos semivariogramas individuais e escalonado. A densidade amostral e espaçamento do semivariograma escalonado indicaram menor número de pontos e maior espaçamento para representar as áreas de agrofloresta e cana-de-açúcar. Palavras-chave: atributos do solo, sul do Amazonas, variabilidade espacial Geostatistical techniques in the evaluation of chemical attributes in Cambisol with agroforestry and sugarcane in Humaita, Amazonas, Brazil ABSTRACTThere is a lack of studies focusing on the spatial behavior of chemical attributes in the Amazon. In this sense, the objective of this study was to use geostatistical techniques in the evaluation of chemical attributes in agroforestry soil and sugarcane in Humaitá, Amazonas. The study was conducted in a rural property in Humaitá, Amazonas. These areas were established knitwear 70.00 mx 70.00 m, with regular spacing of 10.00 m totaling 64 points and then collected soil samples at a depth of 0.0 to 0.20 and 0.40 to 0.60 m. We determined the chemical attributes (pH, OM, P, K, Ca, Mg, SB, CTC, V% and H + Al). They used descriptive statistics and geostatistics which set individual and scaled semivariogram, and then estimated the sample density based on the achievement of semivariograms. The soil attributes presented spatial dependence structure mostly, predominantly moderate degree of spatial dependence, individual and staggered semivariograms. The sample density and spacing of the stepped semivariogram indicated fewer points and increased spacing to represent the areas of agroforestry and sugarcane.
