Modelagem e quantificação da incerteza espacial do potássio disponível no solo por simulações estocásticas

Abstract: Resumo -O objetivo deste trabalho foi avaliar o desempenho da simulação sequencial gaussiana (SSG) e da simulação sequencial indicatriz (SSI) na modelagem da incerteza das predições do K disponível em área de cana-de-açúcar, e comparar as simulações com o método já consagrado de krigagem ordinária (KO). Uma malha amostral com 626 pontos foi instalada em área de 200 ha, no Município de Tabapuã, em São Paulo. As simulações reproduziram a variabilidade dos dados amostrais de K disponível, enquanto a KO superestim… Show more

“…Under these conditions, simulations can help create scenarios for reproducing experimental data (Tagar et al, 2015), which formalize and analyze some error propagation methods for modeling; among them, the Monte Carlo method has general applicability and can be used in models with mathematical formulations (Ortiz et al, 2004). This procedure was used by Ortiz et al (2004), and simulations based on other methods were used by Oliveira et al (2013Oliveira et al ( , 2014 for soil data in Brazil.…”
