Environmental Fate TERRESTRIAL FATE: The study was conducted with 4 soils (red, alluvial, black, and peat) in the laboratory. Regression equations for the Freundlich adsorption isotherms are given. Peat soil showed the highest degree of adsorption. The Rf values of phosphamidon movement in soil, as shown by TLC (Helling, CS and Turner, 1968) showed significant correlations with the adsorption coefficients. Under dry conditions, the fastest degradation was observed during the 1st 5 days in all soils. Under waterlogged conditions, most of the phosphamidon passed into the water phase in the red, alluvial, and black soils.
