ABSTRACT Mining is a significant driver of soil mobilization, which impacts its physical, chemical, and biological properties. Changes in land-use affect the distribution of organic matter fractions in stable aggregates, a process that is still poorly understood, especially in drastically altered areas. Recovering and monitoring soil quality to ensure the sustainable development of agricultural crops in these areas after mining is challenging. This study aimed to evaluate the influence of agronomic practices in soil rehabilitation in a bauxite-mined area after […]

ABSTRACT Brazilian soil scientists have increased the use of the term “soil quality” in their scientific publications in the last decade. However, it remains unclear if those publications only mention “soil quality” in a broad context, or the studies are focused on soil quality assessments, integrating soil chemical, physical and biological indicators. The objective of this systematic review was to carry out a critical analysis of the conception in using the term “soil quality” in recent publications derived from studies […]

No sul de Minas Gerais faz-se a substituição de florestas de araucária por pastagens ou extensos plantios de eucalipto. No entanto, poucos estudos relacionam, de forma ampla, os impactos nos atributos físicos, químicos, microbianos e visuais do solo causados por esta substituição. Com esse objetivo, selecionaram-se áreas com eucalipto, araucária implantada, mata nativa e pasto implantado em Delfim Moreira, MG, no verão de 2006, de onde se retiraram amostras deformadas e indeformadas de solo para análises químicas (pH, P, K, […]
