The present study aimed to investigate the spatial variability of soil penetration resistance (SPR) in cultivation areas ‘BRS Princesa’ banana, evaluate its effects on chemical and physical attributes indicate localized management. experiment was carried out an area which 60 georeferenced points were recorded. SPR measured from cone index 0.40 m depth using impact penetrometer. Disturbed sample...

Soil compaction can occur due to trafficking by heavy equipment and be exacerbated unfavourable conditions such as wet weather. Compaction restrict crop growth increase waterlogging, which the production of greenhouse gas nitrous oxide. Cultivation used alleviate compaction, but this have negative impacts on earthworm abundance carbon dioxide. In study, a field was purposefully compacted using ...

Abstract We report for the first time effects of vehicle traffic and beachgoer trampling on macrobenthic communities Amazonian sandy beaches. Sampling was performed during four consecutive months with different beach use intensity in 2017 (before, vacation, two after vacation period) three contrasting beaches regard to disturbance (Urban: Atalaia; Intermediate: Farol-Velho; Protected: Corvinas)...

Road design is a complex, time-consuming, and very responsible process. To develop high-quality viable road project, it important to start with an accurate geological survey in order define the best layout. Moreover, geotechnical characterisation of foundation soils construction materials as well analysis assessment works are mandatory. Laboratory situ investigations complementary should be car...
