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

Magnetic susceptibility in the prediction of soil attributes in two sugarcane harvesting management systems [PDF]
Engenharia Agrícola, 2013 This study aimed to investigate the potential use of magnetic susceptibility (MS) as pedotransfer function to predict soil attributes under two sugarcane harvesting management systems. For each area of 1 ha (one with green sugarcane mechanized harvesting

SPATIALIZATION OF SOIL CHEMICAL AND PHYSICAL ATTRIBUTES IN AN AGROFORESTRY SYSTEM, SEROPÉDICA, BRAZIL [PDF]
CERNE, 2016 ABSTRACT The purpose of this study was to spatialize the chemical and physical attributes of the soil in an agroforestry system in Seropédica, Rio de Janeiro, Brazil. Thirty-one soil samples were collected from 0-10 cm, 10-20 cm, and 20-40 cm depths, and each sampling point was georeferenced.

Soil physical attributes and corn yield as affected by soil managements and fertilization
, 2022 No-tillage system is an efficient technique in control of soil erosion, when compared with conventional tillage, however, some studies indicate higher compaction under no-tillage, mainly in the surface layer. Strategies that increase the organic matter content, as crop rotation and organic fertilization, can be used to solve the soil compaction.

Soil physical attributes and agronomic characteristics relationships of soybean in no-tillage
Revista Engenharia na Agricultura - REVENG, 2022 The objective of this work was to evaluate the soil physical attributes and their relationship to soybean productivity under no-tillage system. The study was conducted in a Oxisol, based on randomized blocks design, with the treatments: no-tillage for 10 years (0 tractor traffic) and five tractor-traffic intensities (2, 4, 6, 8, and 12 passes), with ...

Physical attributes of a pasture soil in southeast Goiás determined by geostatistics [PDF]
Engenharia Agrícola, 2016 ABSTRACT This study aimed to evaluate the spatial dependence of physical attributes in a soil cultivated with Brachiaria grass. A 12-m regular sampling grid was established within an area of 3.500 m2. Thirty-five soil samples were collected at 0-30 cm depth for particle density, bulk density, texture and total porosity analysis.

Effect of management systems in soil physical attributes
, 2007 Inadequated soil tillage can induce the formation of compacted layer near soil surface. Soil physical attributes were assessed after sixteen years of distinct soil management on a typical dystrophic red latosol located in Passo Fundo, Rio Grande do Sul State, Brazil.
