  • Compacted urban soils improved with composts have long-term benefits for tree growth

    Composting to compacted urban soils can provide a lasting effect that aids tree growth, new research indicates. Urban soils improved with added organic material are less compacted after five years compared with soils that have not been treated with organic composts, the study suggests. Urban soils are often compacted from the construction and repair of buildings, roads and pavements. Compacted ...

  • Precompression stress in soils

    The precompression stress as a factor to assess the mechanical stability of soils is predictable by using pedotransfer functions. Over the past decades arable soils have been deteriorated because of the heavy machinery on the farm. Increase loads enhance subsoil compaction which is mostly irreversible. As a consequence of this deformation, the soil productivity decreases while the erodibility ...


  • Soil sealing in Europe

    The covering of the soil surface with impervious materials as a result of urban development and infrastructure construction is known as soil sealing. The term is also used to describe a change in the nature of the soil leading to impermeability (e.g. compaction by agricultural machinery). Sealed areas are lost to uses such as agriculture or forestry while the ecological soil functions are ...

  • Polluted urban soil damages lime trees

    The impact of polluted urban soil on trees is highlighted in a recent study from Latvia. The researchers found that high salt levels from de-icing chemicals and nutrient imbalance in soil damaged lime trees growing in the city of Riga. Trees planted in cities are an important part of the urban landscape, providing a range of benefits, from enhancing biodiversity to promoting a feeling of ...

  • Soil protection critical for Europe`s economy and ecosystems

    Soil is one of the planet's invaluable resources but continues to be degraded in Europe. Together, the mineral particles, water, air, organic matter, and living organisms that constitute soil perform key functions which underpin our society. Soil is a vital, non-renewable resource for ecosystems, playing an essential role in services such as water purification and food production. It is ...

  • Euro MPs move forward on soil protection directive

    The European Parliament yesterday adopted its first-reading report on the first EU directive on soil protection. Among the key points adopted by MEPs is the setting up of public inventories of contaminated sites within the EU and the need for Member States to draw up remediation strategies. MEPs reinstate a list of potentially soil polluting activities. Member States will be allowed some ...

  • Soil nailing is ideal for tight spaces or areas

    According to OSHA, excavation is one of the most hazardous construction operations. The greatest risk for worker fatalities is from cave-ins. But excavation is a necessary part of many construction projects. There are several different options for earth retention during excavation. The decision is typically made by the Project Team based on project logistics – how deep ...
