In recent years the increase in no-tillage agriculture has resulted in the increase of total herbicide Glyphosate. This is the consequences of breeding of Glyphosate resistant plant. Glyphosate (a P-containing compound) behaves like other P-components in the soil and therefore it is bound to soil Fe-hydroxides. This will result in the formation of bound residues and enrichment in the soil is very likely. The use of Bt toxin (a toxin directed mostly against the European Corn Borer) produced by genetically modified plants will lead to a change in composition of soil organic matter. The Bt toxins are proteins and bound to the outer surface of soil mineral aggregates. They compete with the soil humic substances for binding sites. This results in a complex binding behaviour and the formation of bound residues as all other proteinaceous materials.
