Subsoil compaction caused by heavy sugarbeet harvesters in southern Sweden; III. risk assessment using a soil water model

, 2003
Due to its persistence, subsoil compaction should be avoided, which can be done by setting stress limits depending on the strength of the soil. Such limits must take into account soil moisture status at the time of traffic.

Evaluation des risques de compaction des sols en Région Wallonne (Belgique) [PDF]

, 2010
The proposed Soil Framework Directive COM(2006)232 requires Member States to identify areas at risk of erosion, decline in organic matter, salinisation, compaction, sealing and landslides, as well as to set up an inventory of contaminated sites.

Seasonal change of soil precompression stress in coffee olantation under sub-humid tropical condition

, 2014
Objetivou-se, neste trabalho, avaliar o comportamento da pressão de pré-consolidação, no decorrer de um ano, em um Latossolo Vermelho-Amarelo cultivado com cafeeiros de diferentes tempos de implantação em diversas declividades do terreno. Este estudo foi conduzido em plantações cafeeiras localizadas em Três Pontas, sul de Minas Gerais.

Characterisation of Luvisol compaction under two different tillage systems and field traffic zones by assessing soil mechanical properties

, 2017
Compaction of arable soils is a consequence of tillage systems and agricultural machinery traffic year after year. Its negative effects on crop production and on the environment have been put into evidence by several studies.
