Estimating sample size of soil cone index profiles by bootstrapping
(Sociedade Brasileira de Ciência do Solo, 2017-11)
Measurements of the soil cone index are widely used to assess soil resistanceto root penetration (SR) and to monitor the soil compaction status of agricultural fields. However, soil sampling for SR estimation is a rather ...
Nested sampling: an improved visual-census technique for studying reef fish assemblages
(2008)
Our aim was to devise visual sampling protocols to estimate densities in a morphologically and behaviorally diverse assemblage of reef fishes. The focus was on a design that is cost-effective and produces relatively accurate ...
Prediction of topsoil properties at field-scale by using C-band SAR data
(Elsevier, 2020-07-10)
Designing and validating digital soil mapping (DSM) techniques can facilitate precision agriculture implementation. This study generates and validates a technique for the spatial prediction of soil properties based on ...
Eficiência de grades amostrais e zonas de manejo na acertividade da correção e fertilização em área de agricultura de precisão consolidada
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Agronomia - Agricultura e Ambiente, 2016-02-17)
Soil samples from sampling grids is currently the leading precision farming tool used in Brazil. But it still has doubts about the economic feasibility of using grids with high density points. New technologies such as the ...
Variabilidade espacial das perdas na colheita mecanizada do algodoeiro com diferentes armações de coleta
(2013-07-01)
In any mechanized operation is the common occurrence of losses, and in the case of the harvest is important that these be quantified in order to minimize them. The work aimed was evaluated the influence of spatial quantitative ...
Evaluation of the Computer-based Battery for Oral Language (BILOv3) through the Rasch model for a Brazilian Sample
(Pontifica Univ Javeriana, Fac Psych, 2014-10-01)
There are few tests in Brazil to assess the comprehension of oral language, especially the ones that are computer-based. Thus, this study aimed at investigating psychometric characteristics for a computer-based battery for ...
