Transfer function-noise modeling and spatial interpolation to evaluate the risk of extreme (shallow) water-table levels in the Brazilian Cerrados
(Springer, 2010-12-01)
Water regimes in the Brazilian Cerrados are sensitive to climatological disturbances and human intervention. The risk that critical water-table levels are exceeded over long periods of time can be estimated by applying ...
Meloidogyne exigua (Meloidogynidae) in rubber tree clones during two periods of the year
(2018-12-01)
Meloidogyne exigua Goeldi, race 3 (Nematoda: Tylenchida: Meloidogynidae), has become an important pest for rubber tree plantations. Thus, the objective of this work was to monitor its infestation in rubber tree plantations ...
Variabilidade espacial do fósforo e das frações granulométricas de um Latossolo Vermelho Amarelo
(Univ Federal Ceara, Dept Geol, 2010-01-01)
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 ...

The objective of this work was to evaluate the groundwater contamination risk by tebuthiuron in a sugarcane area, through spatial modeling, in the municipality of Sao Manuel, in the state of Sao Paulo, Brazil. The Araqua ...
Geostatistics applied in soil compaction determination in sugar cane cropping
(Univ Estadual Mato Grosso Sul, 2017-04-01)
The tools of precision agriculture increasingly diversify to facilitate decision making in the field in order to increase crop yields to feed a population that only grows. The responsibility of professional in agronomic ...
Spatial Variability of Soil Organic Matter and Cation Exchange Capacity in an Oxisol under Different Land Uses
(2016-12-30)
Soil properties may exhibit large spatial variability. Frequently this variability is auto-correlated at a certain scale. In addition to soil-forming factors, soil management, land cover, and agricultural system may affect ...
