Critical Limits for Soybean and Black Bean Root Growth, Based on Macroporosity and Penetrability, for Soils with Distinct Texture and Management Systems
(2022-03-01)
Soil compaction is a worldwide problem in agricultural areas, and it is important to define soil properties and reference values that allow knowledge of the compaction level for decision making. The objective of this study ...
Estimation of soil penetration resistance with standardized moisture using modeling by artificial neural networks
(2020-06-01)
One of the most used evaluations to monitor soil compaction is based on soil penetration resistance (SPR). However, since SPR is influenced by soil moisture, this evaluation performed in the field may often lead to incorrect ...
Least limiting water as a soil indicator in an integrated crop-livestock systems of the Cerrado, Brazil
(2019-11-01)
The least limiting water range (LLWR) is widely used as an agronomic indicator of soil physical quality, however few studies have reported its spatial variability, mainly in integrated crop-livestock systems (ICL). This ...
Assessing the soil physical characteristics of the gallery woods area at the hydrographic Mariana sub-catchment for environmental conservation
(2013-01-01)
The objective of this work was to characterize soil physical properties of the gallery woods area at the hydrographic Mariana sub-catchment. The physical attributes evaluated were: bulk density, gravimetric humidity, soil ...
Organic matter and physical attributes of Latosols 30 months after uses in the sugarcane fallow-period
(Univ Federal Rural Pernambuco, 2018-01-01)
The objective this work was to evaluate the organic matter content and the physical attributes of two Red Latosols 30 months after use in the sugarcane fallow-period. The long-term experiment was conducted on two Red ...
MANAGEMENT SYSTEMS: SOIL COVER AND COMPACTION, LONGITUDINAL DISTRIBUTION, AND YIELD OF SOYBEAN CROP
(Soc Brasil Engenharia Agricola, 2019-07-01)
The way the soil is managed can influence its structuring and, consequently, crop yield. Thus, this study aimed to evaluate the effect caused by the management systems plowing followed by two intermediate harrowing operations, ...
Compactação do solo e intervalo hídrico ótimo no crescimento da parte aérea e produtividade da cultura do milho
(2008-04-01)
The aim of this work was to evaluate the effect of soil compaction caused by tractor wheel traffic on the limiting water range (LLWR), shoot growth and levels of compaction and four replications in a completely randomized ...
