Accelerated land use changes have been observed in Brazil. In Northeast, the Caatinga (native vegetation) has been replaced by fruit production, especially by mango and grapevine cultivation. Land use changes, tied to management techniques, can change the soil chemical and physical attribute...

Continuous observations from remote sensors provide high temporal and spatial resolution imagery, and better remote sensing image segmentation techniques are mandatory for efficient analysis. Among them, one of the most applied segmentation techniques is the region growing algorithm. Within this ...

O presente trabalho teve por objetivo verificar o desempenho do modelo HYDRUS-1D na simulação do deslocamento do potássio em colunas de solo segmentadas, preenchidas com Latossolo Vermelho Amarelo (S1) e Nitossolo Vermelho (S2), em condições não saturadas. Para tal, os parâmetros de tra...

The Amazon rain forest was, before the Europeans came, as cultivated as forests anywhere else in the world. It was not 'virgin'. The native people still living within the forest are remnants descended from highly structured societies with suitably developed agriculture and food&...

A substituição da floresta primária por atividades agrícolas, no Latossolo Amarelo, textura média, solo predominante no nordeste paraense, pode ocasionar alterações na estrutura do solo e nos fluxos hídricos. A hipótese em estudo foi que devido ao desmatamento e utilização agrícola desses&#x...
