2. "Horizontes cimentados em Argissolos e Espodossolos dos tabuleiros costeiros e em Neossolos Regolíticos e Planossolos da depressão sertaneja no Nordeste do Brasil" / "Cemented Horizons in ultisol and spodosols from the coastal tablelands and in inceptisols and alfisols from the "sertaneja" depression of Northeast Brazil"
The present study was carried out in cemented horizons in Ultisols and Spodosols from the coastal tablelands, and in Inceptisols and Alfisols from the sertaneja depression of Northeast Brazil. The emphasis was concentrated on the cemented horizons developed in smooth depressions in the coastal tablelands. The main objective was to identify the cementing agen
