Cover crop rotations in no-till system: Short-term CO2 emissions and soybean yield
In addition to improving sustainability in cropping systems, the use of a spring and winter crop rotation system may be a viable option for mitigating soil CO2 emissions (ECO2). This study aimed to determine short-term ...
Soil organic matter and physical attributes affected by crop rotation under no-till
Growing cover crops in systems under no tillage affects different pools of soil organic matter, and eventually soil physical attributes are modified. The objective of this study was to evaluate changes in soil organic ...
Least limiting water range in soil under crop rotations and chiseling
(Sociedade Brasileira de Ciência do Solo, 2011-05-01)
Soil water availability to plants is affected by soil compaction and other variables. The Least Limiting Water Range (LLWR) comprises soil physical variables affecting root growth and soil water availability, and can be ...
Infiltração de água no solo condicionadas pelo uso de plantas de cobertura
(Universidade Federal de Santa MariaBrasilAgronomiaUFSMPrograma de Pós-Graduação em Ciência do SoloCentro de Ciências Rurais, 2017-03-02)
The inclusion of cover crops in agricultural production systems has received attention for the ability to improve the multifunctionality of the soil. In order to improve soil structure and soil physical-hydric properties, ...
Crop rotation and seasonal effects on fatty acid profiles of neutral and phospholipids extracted from no-till agricultural soils
(Wiley Blackwell Publishing, Inc, 2015-03)
Analysis of phospholipids (PLFA) and neutral lipids fatty acids (NLFA) was used to characterize no-till productive agricultural soils associated with different crop rotation levels, replicated across a 400 km transect in ...
