number of agents. Informal information contributes to more intensive conversion until the
proportion of conventional farms is low and informal communication loses its power. As
one could observe, the farms that are unchanged are on the outskirt of the system due to
remoteness and lover intensity of communication with other farms. Such farms are
consequently not given the same amount of informal promotion.

Figure 7 shows second scenario SCA2, where informal information flows are considered,
here it is put to minimum. Increase of the model is almost linear; here the promotion of
organic farming dominates in its influence. Here the importance of informal communication
could be observed as well as impact of certain promotion actions, which is tied to particular
number of organic farms. The proper influence of promotion is also confirmed. In the real
world, such situation would occur in the case of very isolated farms, which have no proper
contacts with other farms and limited access to support resources despite the fact, that the
support level might be high.
