Soil CO(2) emission estimated by different interpolation techniques
(SPRINGER, 2011)
Soil CO(2) emissions are highly variable, both spatially and across time, with significant changes even during a one-day period. The objective of this study was to compare predictions of the diurnal soil CO(2) emissions ...
Soil CO2 emission estimated by different interpolation techniques
(Springer, 2011-08-01)
Soil CO2 emissions are highly variable, both spatially and across time, with significant changes even during a one-day period. The objective of this study was to compare predictions of the diurnal soil CO2 emissions in an ...
HOMOGENEOUS ZONES OF SOIL PROPERTIES FOR IRRIGATION MANAGEMENT IN A VINEYARD
(Soc Brasileira De Ciencia Do Solo, 2014-07-01)
In analysis of the spatial and temporal variability of the factors inherent to agricultural production, geostatistics is the basis for the application of the concepts of precision agriculture. Thus, this study was developed ...
Cokrigagem na estimativa da evapotranspiração em Campinas, SP
(2010)
The quantification of evapotranspiration is great importance for the crops irrigation. This paper aims to map evapotranspiration cokriging through the relative humidity and solar radiation as a variable used to estimate ...
Métodos de interpolação para estimar o ph em solo sob dois manejos de café Arábica
(2010-08-01)
There are many methods used to estimate values in places no sampled for construction of contours maps. The aim of this study was to use the methods of interpolation kriging, inverse of the square of the distance and ...
The use of scaled semivariograms to plan soil sampling in sugarcane fields
(Springer, 2012-10-01)
Spatial sampling designs used to characterize the spatial variability of soil attributes are crucial for science studies. Sample planning for the interpolation of a regionalized variable may use several criteria, which ...
Variabilidade espacial do fósforo e das frações granulométricas de um Latossolo Vermelho Amarelo1
(Universidade Federal do Ceará, 2010)
This study was conducted to study the spatial variability of phosphorus, estimating it through cokriging taking as covariables the size fractions of soil. The study was conducted at the experimental farm INCAPER-ES. The ...
Self-energies for interacting fields with a compactified spatial dimension
(Sociedade Brasileira de Física, 2008-06-01)
We study the self-energy of a model with a tri-linear coupling among spinless fields on a manifold with one spatial dimension compactified. The model is considered to be composed by a quantized scalar field interacting ...
