• Different protozoa taxa present in soil aggregates were counted by a modification of the ring method described by Singh (1946), and the number of positive rings was simulated by the following model : N_t=N_∞[1-e^<-k(t-tr)>] (t>t_r) where N_t is the cumulative number of positive rings at time t, N_∞ is the expected total number of positive rings at infinite time, k is the rate of appearance of positive rings, and t_r is the retardation time. Data sets from short time observations of the aggregates closely fitted with the calculated curves of the model. N_t of mixed population of flagellates or small ciliates increased according to a stepwise curve, in which each step may correspond to a different species group.
