Geostatistical analysis of crop yield maps in a long term no tillage system. Author(s): GUEDES FILHO, O.; VIEIRA, S. R.; CHIBA, M. K.; GREGO, C. R. It is known, for a long time, that crop yields are not uniform at the field. In some places, it is possible to distinguish sites with both low and high yields even within the same area. This work aime... ... Repository: BDPA Publication year: 2010
Evaluation of statistical and geostatistical models of difgital soil properties mapping in tropical mountain regions. Author(s): CARVALHO JUNIOR, W. de; CHAGAS, C. da S.; LAGACHERIE, P.; CALDERANO FILHO, B.; BHERING, S. B. As propriedades dos solos têm grande impacto sobre aspectos econômicos e ambientais da produção agropecuária. As relações quantitativas entre as propriedades dos solos e os fatores que condicionam sua... ... Repository: BDPA Publication year: 2014
Dissimilarity of parameterized maps generated in geostatistics and the assumption of an automatic software model in precision agriculture. Author(s): MALVEZI, K. E. D.; SIBALDELLI, R. N. R.; PEREIRA NETO, O. C.; MORAES, L. A. C.; SAAB, O. J. G. A.; MOREIRA, A. Repository: BDPA Publication year: 2020
Estimating soil loss by laminar erosion using precision agriculture computational tools. Author(s): KRUG, E. T. S.; GOMES, G. J.; SOUZA, E. G. de; GEBLER, L.; SOBJAK, R.; BAZZI, C. L. ABSTRACT: The study aimed to identify and evaluate the spatial variability in laminar erosion in areas using precision agriculture tools. Soil data from three properties in the western region of Paran... ... Repository: BDPA Publication year: 2022
Geostatistical Analysis of NDVI in rotational and continuous grazing pastures. Author(s): GREGO, C. R.; MANJOLIN, R. C.; NOGUEIRA, S. F.; RODRIGUES, C. A. G.; SILVA, G. B. S. da; CONCEIÇÃO, M. P. C.; HERLING, V. R. Livestock rearing is an important economical activity in Brazil, and its production is affected by pasture management methods. In this context, the use of geostatistics to analyze the spatial variabil... ... Repository: BDPA Publication year: 2016
Spatial variability of some biometric attributes of sugarcane plants (variety IACSP93-3046) and its relation to physical and chemical soil attributes. Author(s): GREGO, C. R.; VIEIRA, S. R.; XAVIER, M. A. Tests to evaluate competition between plants, in general do not consider the soil spatial variability, nevertheless, the uniformity rarely is present and can not be assumed without verification. The a... ... Repository: BDPA Publication year: 2010
Aspects of the silvopastoral system correlated with properties of a Typic Quartzipsamment (ENTISOL) in Mato Grosso do Sul, Brazil. Author(s): CORRÊA, A. R.; MONTANARI, R.; LAURA, V. A.; MELOTTO, A. M.; SILVA, E. N. S. da; PELLIN, D. M. P.; SANTOS, A. S. dos In Brazil, grazing mismanagement may lead to soil and pasture degradation. To impede this process, integrated cropping systems such as silvopasture have been an effective alternative, allied with prec... ... Repository: BDPA Publication year: 2015

Variabilidade espacial dos agregados e carbono orgânico total em Neossolo Litólico Eutrófico no município de Gilbués, PI. Author(s): CORADO NETO, F. da C.; SAMPAIO, F. de M. T.; VELOSO, M. E. da C.; MATIAS, S. S. R.; ANDRADE, F. R.; LOBATO, M. G. R. O constante uso do solo, geralmente provoca uma redução no teor de carbono orgânico do solo. Este atributo exerce importante função na agregação do solo. Objetivou-se avaliar a variabilidade espacial... ... Repository: BDPA Publication year: 2015
