Chemical of soils with histic horizon of lakes and riparian of the Savanna, Northern Amazonia, Brazil. The savanna of the northern Amazon of Brazil is an ecosystem that presents lakes and riparian of buriti (Mauritia flexuosa L.) in its landscape. Although these ecosystems are protected by law, they ar... ... Repository: BDPA Publication year: 2019
Comparison of total nitrogen methods applied for histosols and soil horizons with high organic matter content. Author(s): BENITES, V. de M. This study was carried out to correlate total nitrogen analyzed by two different methods: Kjeldahl (wet oxidation) and Perkin-Elmer 2.400 Series II?CHN Mode (dry oxidation or combustion) in Histosols... ...

Comparing methods for extracting heavy metals from Histosols for establishing quality reference values. The diversity of methods for heavy metal extraction from soils complicates comparison of results used by environmental agencies to establish quality reference values. The aim of this study was to eval... ... Repository: BDPA Publication year: 2016
Participação da matéria orgânica na capacidade de troca catiônica em solos antrópicos no Brasil: avaliação de dados secundários. O presente trabalho apresenta uma avaliação de dados secundários, oriundos de diversas pesquisas com as TPI no Brasil, partindo da análise de dados quantitativos com vista a discussões qualitativas no... ...

Resposta de vetiver à aplicação de calcário e fósforo em três classes de solo. O vetiver tem sido bastante utilizado para controle de erosão, principalmente em áreas degradadas em que o horizonte superficial do solo foi removido. O manejo do solo pode influenciar a eficiência de... ... Repository: BDPA Publication year: 2015
The late holocene upper montane cloud forest and high altitude grassland mosaic in the Serra da Igreja, Southern Brazil. Author(s): CURCIO, G. R. Many soils of the highlands of Serra do Mar, as in other mountain ranges, have thick histic horizons that preserve high amounts of carbon. However, the age and constitution of the organic matter of th... ... Repository: BDPA Publication year: 2013
Identifying soil horizons transitions for ground-truthing and interpreting ground penetrating radar (GPR) imagery of Planosols. The Ground Penetrating Radar (GPR) has potential to characterize soils both vertically and horizontally. The effectiveness of using GPR relies on the interpretation of soil targets in the radargrams.... ... Repository: BDPA Publication year: 2023
