Abstract
|
|
|
The adsorption of 2-Chloro-4-(ethylamino)-6-(isopropylamino)-s-trazine (Atrazine) and 2-Chloro-2´ 6´ diethyl-N(methoxymethyl)acetanilide(fllachlor) by 21 Korean surface soils is studied and discussed in relation to some properties of soils.
1. Adsorption of Atrazine was correlated posisively with content of clay and organic matter, but negatively with extractable potassium content and sand content.
2. Adsorption of Alachlor was correlated positively with organic matter, caly content and CEC, but negatively with sand content
3. Isothermal adsorpsion of Alachlur was confirmed to the Freundlich eguation.
