Abstract english

The agar-film and membrane filter methods were used to measure total hyphal length in ten

different soils. The former method resulted in values 1.1 to 3.9 times those of the latter.

Choice of magnification strongly influenced the results. The value for fungal length found at a

magnification of 1250 x was 2 times that found at 800 x or 500 x . The measured mean hyphal diameter was significantly smaller at 1250 x and 800 x compared to 500 x.
