Scientists across the globe face a large challenge during representative soil sample collection when having to carefully retain the physical-chemical structure of the soil. The goal was to validate the performance of a mechanical collector of soil monoliths of adjustable formats and to establish suitable mechanical indicators of the operational equipment. The collector's operating ability, efficiency, and precision were confirmed in terms of the aspects listed: definition of the optimal rotation of work; maintenance of a uniform diameter and height of the monoliths in cylindrical and conical formats; collection efficiency under unfavorable conditions (roots and gravel presence); specification of the ideal soil moisture levels for collection from the various types of soil classes; collection from terrain characterized by uneven topography and evaluation of the wearing out of cutting tool edges (drill).
Qualidade físico-hídrica de monolitos de solo de volumes variados coletados em solos de diferentes granulometrias Physical-hydric quality of soil monoliths of varying volumes collected in soils of different particle sizes
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
