ABSTRACT Organic carbon introduced in soils, mainly through organic matter, has a relevant role in various soil properties and is particularly important in sandy soils. In these soils, the input of organic material is necessary to ensure the sustainability of production systems. This study aimed to investigate the changes in total organic carbon content and its effect on physical properties in areas under different harvest management systems (HMS) after the harvest of eucalyptus. The study was performed in December 2017 […]

The broad soil and ecosystem diversity of the state of Roraima is gradually being replaced by pasture and, depending on the management system adopted, this can be associated with soil physical degradation. Within this context, the aim of the present study was to evaluate and compare the soil physical attributes of an Argissolo Amarelo (Ultisol) under savanna and forest natural ecosystems, and their conversion into a cattle pasture system. The primary treatments were natural savanna (NS), savanna converted to pasture […]
