As for ionic strength, the soil extracts obtained with 0.0005 M CaCl 2 were similar to the surface 199 AGRICULTURAL AND FOOD SCIENCE IN FINLAND Yli-Halla, M. & Hartikainen, H.: Phosphorus desorption to runoff water runoff waters of the Jokioinen and Aurajoki fields (Yli-Halla et al. 1995), and those obtained with 0.005 M CaCl2 corresponded to soil solu- tion (Wiklander and Andersson 1974).As for the solution-to-soil ratio, it was observed in an ear- lier study that the average DRP concentration in the surface runoff in these particular fields was the same as that of soil extracts obtained at the solution-to-soil ratio between 250 and 500 1 kg 1 (Yli-Halla et al. 1995)	cache/afs-72735.pdf	txt/afs-72735.txt
