Quality indices in degraded pasture in hilly relief
Semina: Ciências Agrárias, 2015 Due to the influence of relief on soil variability, homogenous pedogenetic conditions have been recommended for developing soil quality indices based on their chemical, physical and biological attributes. This limits the development and application of an

Physical and chemical attributes of soils of Paraguay River margins [PDF]
Ambiente e Agua - An Interdisciplinary Journal of Applied Science, 2013 This work aimed to analyze chemical and physical attributes of soil of the Paraguay River margins. Four profiles of soil of the margins were selected: passage of Julião (profiles 1 and 2), Chimbuva farm (profile 3) and Barra of Cabaçal (profile 4). Samples for chemical and physical analyses were collected from each of the layers in the margins analyzed.

Soil Physical Attributes in Long-Term Soil Management Systems (Tillage and No-till)
Journal of Agricultural Science, 2020 The period of implantation of the no-tillage system (NTS) is a fundamental factor to the dimension of the changes that occur to the soil's physical, chemical and biological attributes. Thus, the objective of this study was to evaluate the soil changes to the physical attributes and correlate the results to the soil organic matter in areas of ...
