Atributos físicos de um Latossolo Vermelho-Amarelo distrófico sob diferentes usos do solo e floresta nativa
The physical attributes of a soil are important for the sustainability of agricultural and forestry systems, making it necessary to monitor its quality. In recent years, the deterioration of soil quality has been a subject of paramount importance in soil science, as the removal of vegetation cover and the intensive use of mechanization in all cultivation operations can result in a decrease in soil quality productive capacity. In this sense, the aim of this work was to analyze the physical attributes of a dystrophic Red-Yellow Oxisol subjected to different land use alternatives and under native forest. Sample collection and field trials were made up of undisturbed and deformed samples from eucalyptus plantation (PE), cerrado (CE), integrated crop, livestock and forest (ILPF), conventional corn plantation (PCM), extensive pasture (PEX) and native forest (FN). Normal Proctor tests were carried out to evaluate the maximum density and optimum compaction moisture, soil resistance to penetration and basic infiltration velocity (VIB). The
期刊介绍:
Scientia Forestalis is a scientific publication of the IPEF – Institute of Forest Research and Studies, founded in 1968, as a nonprofit institution, in agreement with the LCF – Department of Forest Sciences of the ESALQ – Luiz de Queiroz College of Agriculture of the USP – São Paulo University. Scientia Forestalis, affiliated to the ABEC – Brazilian Association of Scientific Publishers, publishes four issues per year of original papers related to the several fields of the Forest Sciences.
The Editorial Board is composed by the Editor, the Scientific Editors (evaluating the manuscript), and the Associated Editors (helping on the decision of acceptation or not of the manuscript, analyzed by the Peer-Reviewers.
