Many fungi will rot seeds; the prevalence of a particular fungal group as
seed-rotting pathogens depends in part on the plant species, age of
seed, soil type, temperature and moisture. There are many references
on this subject; I would suggest Bruehl's text as a start:
Bruehl, GW 1987. Soilborne Plant Pathogens. Macmillan Pub Co.
For measuring fungal activity in the soil, there are also many techniques
available. I suggest this review of techniques and approaches:
Parkinson, D; Coleman, DC. 1991. Microbial Communities, Activity and
Biomass. Ecosyst. Environ. 34:3-33.
