title: Study of MCPA and MCPP herbicides mobility in soils from North-West Croatia as affected by presence of fertilizers.
abstract: The mobility of acid herbicide (4-chloro-2-methylphenoxy)acetic acid [MCPA] and 2-(4-chloro-2-methylphenoxy)propionic acid [MCPA] in soils of North-West Croatia has been studied by soil thin-layer chromatography (STLC). Mobility of MPCA and MCPP was influenced by the change in concentration of soluble salts and the effect of mineral composition of the system studied, i.e. content of kaolin and sand in soil thin layer. The objective of this work was also to investigate how the mobility of phenoxy herbicides MCPA and MCPP is altered by the presence of fertilizers when both coexist in soil as a result of human activity. It has been found that mobility of acidic herbicides increases with application of fertilizers especially on soil with low clay and low organic matter content.
