  • Definition of management zones in coffee production fields based on apparent soil electrical conductivity
    Valente, Domingos Sárvio Magalhães; Queiroz, Daniel Marçal de; Pinto, Francisco de Assis de Carvalho; Santos, Nerilson Terra; Santos, Fábio Lúcio (Escola Superior de Agricultura "Luiz de Queiroz", 2012-05)
    Fertilizer application at variable rates requires dense sampling to determine the resulting field spatial variability. Defining management zones is a technique that facilitates the variable-rate application of agricultural ...
  • Sampling density for characterizing the physical quality of a soil under coffee cultivation in southwestern Minas Gerais
    Silvero, Nélida E. Q.; Marques Júnior, José; Siqueira, Diego S.; Gomes, Romário P.; Costa, Milene M. R. (Associação Brasileira de Engenharia Agrícola, 2018-09)
    The elaboration of maps to characterize the spatial variability of soil attributes assists in the strategic planning and decision making of agricultural managers. Precision and accuracy of maps are related to the ideal ...
  • Sampling design of soil physical properties in a conilon coffee field
    Santos, Eduardo Oliveira de Jesus; Gontijo, Ivoney; Silva, Marcelo Barreto da; Partelli, Fábio Luiz (Sociedade Brasileira de Ciência do Solo, 2017)
    Establishing the number of samples required to determine values of soil physical properties ultimately results in optimization of labor and allows better representation of such attributes. The objective of this study was ...
  • Spatial correlation between the chlorophyll index and foliar npk levels in coffee crop
    Zanella, Marco Antonio; Rodrigues Junior, Francelino Augusto; Sousa, Emanoel Di Tarso dos Santos; Martins, Rodrigo Nogueira; Calijuri, Maria Lúcia (Editora UFLA, 2020)
    Detection of spatial variability of data that can improve crop management is a key factor for precision agriculture. In agriculture, there is a need for tools to assist farmers in decision-making about proper nutrient ...
