Absorption and degradation of 0.2% Celangulin EC in soil

Abstract:

Absorption,leaching and degradation of 0.2% Celangulin EC in soil were studied.The result showed that Celangulin was absorbed mainly by soil phase when it reached equilibrium in soil-water system.The half-lifes in soils of wheat,vegetable and paddy fields were 199.75,167.43 and 165.43 hours respectively.
