Atributos físicos de latossolo vermelho sob pousio ou cultivado com forrageiras tropicais sob pastejo
(2012-04-26)
The objective was to study the physical attributes of an Oxisol under fallow or planted with tropical grasses under grazing. The experiment was conducted under the experimental design of randomized blocks in split-plot 2 ...
Safflower root and shoot growth affected by soil compaction
(Inst Agronomico, 2018-04-01)
Safflower (Carthamus tinctorius L.1 is a commercial seed crop grown for its good yield of high-quality oil, It is tolerant to water stress but may be sensitive to soil compaction. The aim of this study was to assess safflower ...
Safflower root and shoot growth affected by soil compaction
(Instituto Agronômico de Campinas, 2018-04-23)
Safflower (Carthamus tinctorius L.) is a commercial seed crop grown for its good yield of high-quality oil. It is tolerant to water stress but may be sensitive to soil compaction. The aim of this study was to assess safflower ...
Qualidade física de um latossolo vermelho, sob sistema de semeadura direta e cultivo convencional
(2014-01-01)
The understanding and quantification of the impact of tillage systems in their physical quality are fundamental in the development of sustainable agricultural systems. This study aimed to evaluate the quality of an Oxisol ...
PHYSICAL QUALITY OF AN OXISOL UNDER NO-TILLAGE AND CONVENTIONAL TILLAGE
(Univ Federal Uberlandia, 2014-09-01)
The understanding and quantification of the impact of tillage systems in their physical quality are fundamental in the development of sustainable agricultural systems. This study aimed to evaluate the quality of an Oxisol ...
PHYSICAL QUALITY OF AN OXISOL UNDER NO-TILLAGE AND CONVENTIONAL TILLAGE
(Univ Federal Uberlandia, 2015)
Method to estimate soil macroporosity and microporosity based on sand content and bulk density
(Sociedade Brasileira de Ciência do Solo, 2011)
Macroporosity is often used in the determination of soil compaction. Reduced macroporosity can lead to poor drainage, low root aeration and soil degradation. The aim of this study was to develop and test different models ...
SOIL PROPERTIES AND CARBON ACUMULATION IN AN INTEGRATED CROP-LIVESTOCK SYSTEM UNDER NO-TILLAGE
(Soc Brasileira De Ciencia Do Solo, 2015-05-01)
In production systems such as the integrated crop-livestock system (ICL) under no-tillage, improvements have been observed in chemical, physical, and biological soil properties. Therefore, we aimed to evaluate the changes ...
Influence of sand gradation on compaction of loess soils
(Elsevier Science, 2020-02)
Assessing the interaction among soil organic carbon (OC), Atterberg limits and soil texture, especially sand gradation, in maximum bulk density (BDMAX) can improve prediction of soil compactibility. Our objectives were a) ...
Physical quality indicators and mechanical behavior of agricultural soils of Argentina
(Public Library of Science, 2016-04)
Mollisols of Santa Fe have different tilth and load support capacity. Despite the importance of these attributes to achieve a sustainable crop production, few information is available. The objectives of this study are i) ...
