A model analysis on nitrate leaching under different soil and climate conditions and use of catch crops [PDF]
, 2005 The use of crops and catch crops with deep rooting can strongly improve the possibility of retaining nitrate-N that will otherwise be leached to the deeper soil layers and end up in the surrounding environment.

Fate of the organophosphate herbicide glyphosate in arable soils and its relationship to soil phosphorus status [PDF]
, 2009 Glyphosate is one of the world's most widely used herbicides. This study was undertaken to unravel the factors affecting its movement, sorption, persistence and leachability in different Finnish soils to create a sound basis for risk assessment. Field

Soil vapor extraction in sandy soils: Influence of airflow rate
Chemosphere, 2008 Airflow rate is one of the most important parameters for the soil vapor extraction of contaminated sites, due to its direct influence on the mass transfer occurring during the remediation process. This work reports the study of airflow rate influence on soil vapor extractions, performed in sandy soils contaminated with benzene, toluene, ethylbenzene ...

Physical properties of tropical sandy soils: A large range of behaviours
, 2005 Sandy soils are often considered as soils with physical properties that are easily defined, however they are far from being simple. This is particularly the case for sandy soils in the tropics where they are subjected to a cycle of wetting and drying ...
